|

|
* In addition to the normal scheme of including header files like
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* #include <freetype/freetype.h>
|

|
* #include <freetype/ftglyph.h>
|

|
* ```
|
||||||
|
*
|
||||||
|
* it is possible to used named macros instead. They can be used
|
||||||
|
* directly in `#include` statements as in
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* #include FT_FREETYPE_H
|
||||||
|
* #include FT_MULTIPLE_MASTERS_H
|
||||||
|
* #include FT_GLYPH_H
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* These macros were introduced to overcome the infamous 8.3~naming rule
|
||||||
|
* required by DOS (and `FT_MULTIPLE_MASTERS_H` is a lot more meaningful
|
||||||
|
* than `ftmm.h`).

|
* USER-SELECTABLE CONFIGURATION MACROS
|
||||||
|
*
|
||||||
|
* This file contains the default configuration macro definitions for a
|
||||||
|
* standard build of the FreeType library. There are three ways to use
|
||||||
|
* this file to build project-specific versions of the library:
|
||||||
|
*
|
||||||
|
* - You can modify this file by hand, but this is not recommended in
|
||||||
|
* cases where you would like to build several versions of the library
|
||||||
|
* from a single source directory.
|
||||||
|
*
|
||||||
|
* - You can put a copy of this file in your build directory, more
|
||||||
|
* precisely in `$BUILD/freetype/config/ftoption.h`, where `$BUILD` is
|
||||||
|
* the name of a directory that is included _before_ the FreeType include
|
||||||
|
* path during compilation.
|
||||||
|
*
|
||||||
|
* The default FreeType Makefiles use the build directory
|
||||||
|
* `builds/<system>` by default, but you can easily change that for your
|
||||||
|
* own projects.
|
||||||
|
*
|
||||||
|
* - Copy the file <ft2build.h> to `$BUILD/ft2build.h` and modify it
|
||||||
|
* slightly to pre-define the macro `FT_CONFIG_OPTIONS_H` used to locate
|
||||||
|
* this file during the build. For example,
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* #define FT_CONFIG_OPTIONS_H <myftoptions.h>
|
||||||
|
* #include <freetype/config/ftheader.h>
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* will use `$BUILD/myftoptions.h` instead of this file for macro
|
||||||
|
* definitions.
|
||||||
|
*
|
||||||
|
* Note also that you can similarly pre-define the macro
|
||||||
|
* `FT_CONFIG_MODULES_H` used to locate the file listing of the modules
|
||||||
|
* that are statically linked to the library at compile time. By
|
||||||
|
* default, this file is `<freetype/config/ftmodule.h>`.
|
||||||
|
*
|
||||||
|
* We highly recommend using the third method whenever possible.

* This value is associated with the 'Infinality' moniker, contributed by

||||||
|
* an individual nicknamed Infinality with the goal of making TrueType
|
||||||
|
* fonts render better than on Windows. A high amount of configurability
|
||||||
|
* and flexibility, down to rules for single glyphs in fonts, but also
|
||||||
|
* very slow. Its experimental and slow nature and the original
|
||||||
|
* developer losing interest meant that this option was never enabled in
|
||||||
|
* default builds.
|
||||||
|
*
|
||||||
|
* The corresponding interpreter version is v38.
|
||||||
|
*
|
||||||
|
* Value 2:
|
||||||
|
* The new default mode for the TrueType driver. The Infinality code
|
||||||
|
* base was stripped to the bare minimum and all configurability removed
|
||||||
|
* in the name of speed and simplicity. The configurability was mainly
|
||||||
|
* aimed at legacy fonts like 'Arial', 'Times New Roman', or 'Courier'.
|
||||||
|
* Legacy fonts are fonts that modify vertical stems to achieve clean
|
||||||
|
* black-and-white bitmaps. The new mode focuses on applying a minimal
|
||||||
|
* set of rules to all fonts indiscriminately so that modern and web
|
||||||
|
* fonts render well while legacy fonts render okay.
|
||||||
|
*
|
||||||
|
* The corresponding interpreter version is v40.
|
||||||
|
*
|
||||||
|
* Value 3:
|
||||||
|
* Compile both, making both v38 and v40 available (the latter is the
|
||||||
|
* default).
|
||||||
|
*
|
||||||
|
* By undefining these, you get rendering behavior like on Windows without
|
||||||
|
* ClearType, i.e., Windows XP without ClearType enabled and Win9x
|
||||||
|
* (interpreter version v35). Or not, depending on how much hinting blood
|
||||||
|
* and testing tears the font designer put into a given font. If you
|
||||||
|
* define one or both subpixel hinting options, you can switch between
|
||||||
|
* between v35 and the ones you define (using `FT_Property_Set`).
|
||||||
|
*
|
||||||
|
* This option requires `TT_CONFIG_OPTION_BYTECODE_INTERPRETER` to be

|
* function returns a read-write array, which means that a calling
|
||||||
|
* application can modify the palette entries on demand.
|
||||||
|
*
|
||||||
|
* A corollary of (2) is that calling the function, then modifying some
|
||||||
|
* values, then calling the function again with the same arguments resets
|
||||||
|
* all color entries to the original 'CPAL' values; all user modifications
|

* are lost.

* having `num_palette_entries` elements (as found in the
|
||||||
|
* `FT_Palette_Data` structure). If `apalette` is set to `NULL`, no

|
||||||
|
* `FT_ERROR_DEF_` macro is the error label; by default, the prefix
|
||||||
|
* `FT_Err_` gets added so that you get error names like
|

|
* `FT_Err_Cannot_Open_Resource`. The second argument is the error code,
|
||||||
|
* and the last argument an error string, which is not used by FreeType.
|
||||||
|
*
|
||||||
|
* Within your application you should **only** use error names and
|
||||||
|
* **never** its numeric values! The latter might (and actually do)
|
||||||
|
* change in forthcoming FreeType versions.
|
||||||
|
*
|
||||||
|
* Macro `FT_NOERRORDEF_` defines `FT_Err_Ok`, which is always zero. See
|

|
* the 'Error Enumerations' subsection how to automatically generate a

|
||||||
|
* Error Enumerations
|
||||||
|
*
|
||||||
|
* @abstract:
|
||||||
|
* How to handle errors and error strings.
|
||||||
|
*
|
||||||
|
* @description:
|
||||||
|
* The header file `fterrors.h` (which is automatically included by
|
||||||
|
* `freetype.h` defines the handling of FreeType's enumeration
|
||||||
|
* constants. It can also be used to generate error message strings
|
||||||
|
* with a small macro trick explained below.
|
||||||
|
*
|
||||||
|
* **Error Formats**
|
||||||
|
*
|
||||||
|
* The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be
|
||||||
|
* defined in `ftoption.h` in order to make the higher byte indicate the
|
||||||
|
* module where the error has happened (this is not compatible with
|
||||||
|
* standard builds of FreeType~2, however). See the file `ftmoderr.h`
|
||||||
|
* for more details.
|
||||||
|
*
|
||||||
|
* **Error Message Strings**
|
||||||
|
*
|
||||||
|
* Error definitions are set up with special macros that allow client
|
||||||
|
* applications to build a table of error message strings. The strings
|
||||||
|
* are not included in a normal build of FreeType~2 to save space (most
|
||||||
|
* client applications do not use them).
|
||||||
|
*
|
||||||
|
* To do so, you have to define the following macros before including
|
||||||
|
* this file.
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* FT_ERROR_START_LIST
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* This macro is called before anything else to define the start of the
|
||||||
|
* error list. It is followed by several `FT_ERROR_DEF` calls.
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* FT_ERROR_DEF( e, v, s )
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* This macro is called to define one single error. 'e' is the error
|
||||||
|
* code identifier (e.g., `Invalid_Argument`), 'v' is the error's
|
||||||
|
* numerical value, and 's' is the corresponding error string.
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* FT_ERROR_END_LIST
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* This macro ends the list.
|
||||||
|
*
|
||||||
|
* Additionally, you have to undefine `FTERRORS_H_` before #including
|
||||||
|
* this file.
|
||||||
|
*
|
||||||
|
* Here is a simple example.
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* #undef FTERRORS_H_
|
||||||
|
* #define FT_ERRORDEF( e, v, s ) { e, s },
|
||||||
|
* #define FT_ERROR_START_LIST {
|
||||||
|
* #define FT_ERROR_END_LIST { 0, NULL } };
|
||||||
|
*
|
||||||
|
* const struct
|
||||||
|
* {
|
||||||
|
* int err_code;
|
||||||
|
* const char* err_msg;
|
||||||
|
* } ft_errors[] =
|
||||||
|
*
|
||||||
|
* #include <freetype/fterrors.h>
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* An alternative to using an array is a switch statement.
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* #undef FTERRORS_H_
|
||||||
|
* #define FT_ERROR_START_LIST switch ( error_code ) {
|
||||||
|
* #define FT_ERRORDEF( e, v, s ) case v: return s;
|
||||||
|
* #define FT_ERROR_END_LIST }
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should
|
||||||
|
* be replaced with `FT_ERROR_BASE(error_code)` in the last example.

|

|
* Return a glyph's 'control box'. The control box encloses all the
|
||||||
|
* outline's points, including Bezier control points. Though it
|
||||||
|
* coincides with the exact bounding box for most glyphs, it can be
|
||||||
|
* slightly larger in some situations (like when rotating an outline that
|
||||||
|
* contains Bezier outside arcs).
|
||||||
|
*
|
||||||
|
* Computing the control box is very fast, while getting the bounding box
|
||||||
|
* can take much more time as it needs to walk over all segments and arcs
|
||||||
|
* in the outline. To get the latter, you can use the 'ftbbox'
|
||||||
|
* component, which is dedicated to this single task.
|
||||||
|
*
|
||||||
|
* @input:
|
||||||
|
* glyph ::
|
||||||
|
* A handle to the source glyph object.

|
*
|

* mode ::
|
||||||
|
* The mode that indicates how to interpret the returned bounding box
|
||||||
|
* values.
|
||||||
|
*
|
||||||
|
* @output:
|
||||||
|
* acbox ::
|
||||||
|
* The glyph coordinate bounding box. Coordinates are expressed in
|
||||||
|
* 1/64th of pixels if it is grid-fitted.
|
||||||
|
*
|
||||||
|
* @note:
|
||||||
|
* Coordinates are relative to the glyph origin, using the y~upwards
|
||||||
|
* convention.
|
||||||
|
*
|
||||||
|
* If the glyph has been loaded with @FT_LOAD_NO_SCALE, `bbox_mode` must
|
||||||
|
* be set to @FT_GLYPH_BBOX_UNSCALED to get unscaled font units in 26.6
|
||||||
|
* pixel format. The value @FT_GLYPH_BBOX_SUBPIXELS is another name for
|
||||||
|
* this constant.
|
||||||
|
*
|
||||||
|
* If the font is tricky and the glyph has been loaded with
|
||||||
|
* @FT_LOAD_NO_SCALE, the resulting CBox is meaningless. To get
|
||||||
|
* reasonable values for the CBox it is necessary to load the glyph at a
|
||||||
|
* large ppem value (so that the hinting instructions can properly shift
|
||||||
|
* and scale the subglyphs), then extracting the CBox, which can be
|
||||||
|
* eventually converted back to font units.
|
||||||
|
*
|
||||||
|
* Note that the maximum coordinates are exclusive, which means that one
|
||||||
|
* can compute the width and height of the glyph image (be it in integer
|
||||||
|
* or 26.6 pixels) as:
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* width = bbox.xMax - bbox.xMin;
|
||||||
|
* height = bbox.yMax - bbox.yMin;
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* Note also that for 26.6 coordinates, if `bbox_mode` is set to
|
||||||
|
* @FT_GLYPH_BBOX_GRIDFIT, the coordinates will also be grid-fitted,
|
||||||
|
* which corresponds to:
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* bbox.xMin = FLOOR(bbox.xMin);
|
||||||
|
* bbox.yMin = FLOOR(bbox.yMin);
|
||||||
|
* bbox.xMax = CEILING(bbox.xMax);
|
||||||
|
* bbox.yMax = CEILING(bbox.yMax);
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* To get the bbox in pixel coordinates, set `bbox_mode` to
|
||||||
|
* @FT_GLYPH_BBOX_TRUNCATE.
|
||||||
|
*
|
||||||
|

|

|
* Subpixel Rendering
|
||||||
|
*
|
||||||
|
* @abstract:
|
||||||
|
* API to control subpixel rendering.
|
||||||
|
*
|
||||||
|
* @description:
|
||||||
|
* FreeType provides two alternative subpixel rendering technologies.
|
||||||
|
* Should you define `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` in your
|
||||||
|
* `ftoption.h` file, this enables ClearType-style rendering.
|
||||||
|
* Otherwise, Harmony LCD rendering is enabled. These technologies are
|
||||||
|
* controlled differently and API described below, although always
|
||||||
|
* available, performs its function when appropriate method is enabled
|
||||||
|
* and does nothing otherwise.
|
||||||
|
*
|
||||||
|
* ClearType-style LCD rendering exploits the color-striped structure of
|
||||||
|
* LCD pixels, increasing the available resolution in the direction of
|
||||||
|
* the stripe (usually horizontal RGB) by a factor of~3. Using the
|
||||||
|
* subpixels coverages unfiltered can create severe color fringes
|
||||||
|
* especially when rendering thin features. Indeed, to produce
|
||||||
|
* black-on-white text, the nearby color subpixels must be dimmed
|
||||||
|
* equally.
|
||||||
|
*
|
||||||
|
* A good 5-tap FIR filter should be applied to subpixel coverages
|
||||||
|
* regardless of pixel boundaries and should have these properties:
|
||||||
|
*
|
||||||
|
* 1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid
|
||||||
|
* any shifts in appearance.
|
||||||
|
*
|
||||||
|
* 2. It should be color-balanced, meaning a~+ b~=~c, to reduce color
|
||||||
|
* fringes by distributing the computed coverage for one subpixel to
|
||||||
|
* all subpixels equally.
|
||||||
|
*
|
||||||
|
* 3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain
|
||||||
|
* overall brightness.
|
||||||
|
*
|
||||||
|
* Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less
|
||||||
|
* forgiving of non-ideal gamma curves of a screen (and viewing angles),
|
||||||
|
* beveled filters are fuzzier but more tolerant.
|
||||||
|
*
|
||||||
|
* Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights
|
||||||
|
* API to specify a low-pass filter, which is then applied to
|
||||||
|
* subpixel-rendered bitmaps generated through @FT_Render_Glyph.
|
||||||
|
*
|
||||||
|
* Harmony LCD rendering is suitable to panels with any regular subpixel
|
||||||
|
* structure, not just monitors with 3 color striped subpixels, as long
|
||||||
|
* as the color subpixels have fixed positions relative to the pixel
|
||||||
|
* center. In this case, each color channel is then rendered separately
|
||||||
|
* after shifting the outline opposite to the subpixel shift so that the
|
||||||
|
* coverage maps are aligned. This method is immune to color fringes
|
||||||
|
* because the shifts do not change integral coverage.
|
||||||
|
*
|
||||||
|
* The subpixel geometry must be specified by xy-coordinates for each
|
||||||
|
* subpixel. By convention they may come in the RGB order: {{-1/3, 0},
|
||||||
|
* {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},
|
||||||
|
* {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.
|
||||||
|
*
|
||||||
|
* Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.
|
||||||
|
* If one follows the RGB order convention, the same order applies to the
|
||||||
|
* resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps. Note,
|
||||||
|
* however, that the coordinate frame for the latter must be rotated
|
||||||
|
* clockwise. Harmony with default LCD geometry is equivalent to
|
||||||
|
* ClearType with light filter.
|
||||||
|
*
|
||||||
|
* As a result of ClearType filtering or Harmony rendering, the
|
||||||
|
* dimensions of LCD bitmaps can be either wider or taller than the
|
||||||
|
* dimensions of the corresponding outline with regard to the pixel grid.
|
||||||
|
* For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to
|
||||||
|
* the left, and 2~subpixels to the right. The bitmap offset values are
|
||||||
|
* adjusted accordingly, so clients shouldn't need to modify their layout
|
||||||
|
* and glyph positioning code when enabling the filter.
|
||||||
|
*
|
||||||
|
* The ClearType and Harmony rendering is applicable to glyph bitmaps
|
||||||
|
* rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and
|
||||||
|
* @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V
|
||||||
|
* is specified. This API does not control @FT_Outline_Render and
|
||||||
|
* @FT_Outline_Get_Bitmap.
|
||||||
|
*
|
||||||
|
* The described algorithms can completely remove color artefacts when
|
||||||
|
* combined with gamma-corrected alpha blending in linear space. Each of
|
||||||
|
* the 3~alpha values (subpixels) must by independently used to blend one
|
||||||
|
* color channel. That is, red alpha blends the red channel of the text
|
||||||
|
* color with the red channel of the background pixel.

|

|
* In certain builds of the library, LZW compression recognition is

|

||||||
|
* re-open the face with it.
|
||||||
|
*
|
||||||
|
* The stream implementation is very basic and resets the decompression
|
||||||
|
* process each time seeking backwards is needed within the stream,
|
||||||
|
* which significantly undermines the performance.

|
||||||
|
*
|
||||||
|
* This file is used to define the FreeType module error codes.
|
||||||
|
*
|
||||||
|
* If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
|
||||||
|
* set, the lower byte of an error value identifies the error code as
|
||||||
|
* usual. In addition, the higher byte identifies the module. For
|
||||||
|
* example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
|
||||||
|
* error `TT_Err_Invalid_File_Format` has value 0x1303, the error
|
||||||
|
* `T1_Err_Invalid_File_Format` has value 0x1403, etc.
|
||||||
|
*
|
||||||
|
* Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
|
||||||
|
* including the high byte.
|
||||||
|
*
|
||||||
|
* If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
|
||||||
|
* error value is set to zero.
|
||||||
|
*
|
||||||
|
* To hide the various `XXX_Err_` prefixes in the source code, FreeType
|
||||||
|
* provides some macros in `fttypes.h`.
|
||||||
|
*
|
||||||
|
* FT_ERR( err )
|
||||||
|
*
|
||||||
|
* Add current error module prefix (as defined with the `FT_ERR_PREFIX`
|
||||||
|
* macro) to `err`. For example, in the BDF module the line
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* error = FT_ERR( Invalid_Outline );
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* expands to
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* error = BDF_Err_Invalid_Outline;
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* For simplicity, you can always use `FT_Err_Ok` directly instead of
|
||||||
|
* `FT_ERR( Ok )`.
|
||||||
|
*
|
||||||
|
* FT_ERR_EQ( errcode, err )
|
||||||
|
* FT_ERR_NEQ( errcode, err )
|
||||||
|
*
|
||||||
|
* Compare error code `errcode` with the error `err` for equality and
|
||||||
|
* inequality, respectively. Example:
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* if ( FT_ERR_EQ( error, Invalid_Outline ) )
|
||||||
|
* ...
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* Using this macro you don't have to think about error prefixes. Of
|
||||||
|
* course, if module errors are not active, the above example is the
|
||||||
|
* same as
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* if ( error == FT_Err_Invalid_Outline )
|
||||||
|
* ...
|
||||||
|
* ```
|
||||||
|
*
|
||||||
|
* FT_ERROR_BASE( errcode )
|
||||||
|
* FT_ERROR_MODULE( errcode )
|
||||||
|
*
|
||||||
|
* Get base error and module error code, respectively.
|
||||||
|
*
|
||||||
|
* It can also be used to create a module error message table easily with
|
||||||
|
* something like
|
||||||
|
*
|
||||||
|
* ```
|
||||||
|
* #undef FTMODERR_H_

|

|

|
||||||
|
* with a straight line between the outer corners of each stroke.
|

|
* FT_STROKER_LINEJOIN_MITER_FIXED ::

|
* limit is exceeded. The outer edges of the strokes for the two
|

|
* segments are extended until they meet at an angle. A bevel join

|
* (see above) is used if the segments meet at too sharp an angle and
|
||||||
|
* the outer edges meet beyond a distance corresponding to the meter
|
||||||
|
* limit. This prevents long spikes being created.
|

|

|
* FT_WinFNT_ID_OEM ::
|
||||||
|
* From Michael Poettgen <michael@poettgen.de>:
|
||||||
|
*
|
||||||
|
* The 'Windows Font Mapping' article says that `FT_WinFNT_ID_OEM` is
|
||||||
|
* used for the charset of vector fonts, like `modern.fon`,
|
||||||
|
* `roman.fon`, and `script.fon` on Windows.
|
||||||
|
*
|
||||||
|
* The 'CreateFont' documentation says: The `FT_WinFNT_ID_OEM` value
|
||||||
|
* specifies a character set that is operating-system dependent.
|
||||||
|
*
|
||||||
|
* The 'IFIMETRICS' documentation from the 'Windows Driver Development
|
||||||
|
* Kit' says: This font supports an OEM-specific character set. The
|
||||||
|
* OEM character set is system dependent.
|
||||||
|
*
|
||||||
|
* In general OEM, as opposed to ANSI (i.e., 'cp1252'), denotes the
|
||||||
|
* second default codepage that most international versions of Windows
|
||||||
|
* have. It is one of the OEM codepages from
|
||||||
|
*
|
||||||
|
* https://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers
|
||||||
|
* ,
|
||||||
|
*
|
||||||
|
* and is used for the 'DOS boxes', to support legacy applications. A
|
||||||
|
* German Windows version for example usually uses ANSI codepage 1252
|
||||||
|
* and OEM codepage 850.

|
||||||
|
* @note:
|
||||||
|
* The values returned are not pointers into the internal structures of
|

|
* the face, but are 'fresh' copies, so that the memory containing them
|
||||||
|
* belongs to the calling application. This also enforces the
|
||||||
|
* 'read-only' nature of these values, i.e., this function cannot be
|
||||||
|
* used to manipulate the face.
|
||||||
|
*
|
||||||
|
* `value` is a void pointer because the values returned can be of
|
||||||
|
* various types.
|
||||||
|
*
|
||||||
|
* If either `value` is `NULL` or `value_len` is too small, just the
|
||||||
|
* required memory size for the requested entry is returned.
|
||||||
|
*
|
||||||
|
* The `idx` parameter is used, not only to retrieve elements of, for
|
||||||
|
* example, the FontMatrix or FontBBox, but also to retrieve name keys
|
||||||
|
* from the CharStrings dictionary, and the charstrings themselves. It

||||||
|
* is ignored for atomic values.
|

|
*
|
||||||
|
* `PS_DICT_BLUE_SCALE` returns a value that is scaled up by 1000. To
|
||||||
|
* get the value as in the font stream, you need to divide by 65536000.0
|
||||||
|
* (to remove the FT_Fixed scale, and the x1000 scale).
|
||||||
|
*
|
||||||
|
* IMPORTANT: Only key/value pairs read by the FreeType interpreter can
|
||||||
|
* be retrieved. So, for example, PostScript procedures such as NP, ND,
|
||||||
|
* and RD are not available. Arbitrary keys are, obviously, not be
|
||||||
|
* available either.
|
||||||
|
*

/*!

|

|
*
|
||||||
|
* <pre>
|
||||||
|
* 1, 2, 4, 8, 16 and 32 bit data access within an array of 32-bit words
|
||||||
|
*
|
||||||
|
* This is used primarily to access 1, 2, 4, 8, 16 and 32 bit pixels
|
||||||
|
* in a line of image data, represented as an array of 32-bit words.
|
||||||
|
*
|
||||||
|
* pdata: pointer to first 32-bit word in the array
|
||||||
|
* n: index of the pixel in the array
|
||||||
|
*
|
||||||
|
* Function calls for these accessors are defined in arrayaccess.c.
|
||||||
|
*
|
||||||
|
* However, for efficiency we use the inline macros for all accesses.
|
||||||
|
* Even though the 2 and 4 bit set* accessors are more complicated,
|
||||||
|
* they are about 10% faster than the function calls.
|
||||||
|
*
|
||||||
|
* The 32 bit access is just a cast and ptr arithmetic. We include
|
||||||
|
* it so that the input ptr can be void*.
|
||||||
|
*
|
||||||
|
* At the end of this file is code for invoking the function calls
|
||||||
|
* instead of inlining.
|
||||||
|
*
|
||||||
|
* The macro SET_DATA_BIT_VAL(pdata, n, val) is a bit slower than
|
||||||
|
* if (val == 0)
|
||||||
|
* CLEAR_DATA_BIT(pdata, n);
|
||||||
|
* else
|
||||||
|
* SET_DATA_BIT(pdata, n);
|
||||||
|
*
|
||||||
|
* Some compilers complain when the SET macros are surrounded by
|
||||||
|
* parentheses, because parens require an evaluation and it is not
|
||||||
|
* defined for SET macros. If SET_DATA_QBIT were defined as a
|
||||||
|
* compound macro, in analogy to l_setDataQbit(), it requires
|
||||||
|
* surrounding bracces:
|
||||||
|
* #define SET_DATA_QBIT(pdata, n, val) \
|
||||||
|
* {l_uint32 *_TEMP_WORD_PTR_; \
|
||||||
|
* _TEMP_WORD_PTR_ = (l_uint32 *)(pdata) + ((n) >> 3); \
|
||||||
|
* *_TEMP_WORD_PTR_ &= ~(0xf0000000 >> (4 * ((n) & 7))); \
|
||||||
|
* *_TEMP_WORD_PTR_ |= (((val) & 15) << (28 - 4 * ((n) & 7)));}
|
||||||
|
* but if used in an if/else
|
||||||
|
* if (x)
|
||||||
|
* SET_DATA_QBIT(...);
|
||||||
|
* else
|
||||||
|
* ...
|
||||||
|
* the compiler sees
|
||||||
|
* if (x)
|
||||||
|
* {......};
|
||||||
|
* else
|
||||||
|
* ...
|
||||||
|
* The semicolon comes after the brace and will not compile.
|
||||||
|
* This can be fixed in the call by either omitting the semicolon
|
||||||
|
* or requiring another set of braces around SET_DATA_QBIT(), but
|
||||||
|
* both these options break compatibility with current code, and
|
||||||
|
* require special attention by anyone using the macros.
|
||||||
|
*
|
||||||
|
* There are (at least) two ways to fix this in the macro definitions,
|
||||||
|
* suggested by Dave Bryan.
|
||||||
|
* (1) Surround the braces in the macro above with
|
||||||
|
* do {....} while(0)
|
||||||
|
* Then the semicolon just terminates the expression.
|
||||||
|
* (2) Reduce the blocks to a single expression; e.g,
|
||||||
|
* *((l_uint32 *)(pdata) + ((n) >> 3)) = \
|
||||||
|
* *((l_uint32 *)(pdata) + ((n) >> 3)) \
|
||||||
|
* & ~(0xf0000000 >> (4 * ((n) & 7))) \
|
||||||
|
* | (((val) & 15) << (28 - 4 * ((n) & 7)))
|
||||||
|
* This appears to cause redundant computation, but the compiler
|
||||||
|
* should evaluate the common subexpression only once.
|
||||||
|
* All these methods have the same performance, giving about 300M
|
||||||
|
* SET_DATA_QBIT operations per second on a fast 64 bit system.
|
||||||
|
* Using the function calls instead of the macros results in about 250M
|
||||||
|
* SET_DATA_QBIT operations per second, a performance hit of nearly 20%.

* Contains the following struct
|
||||||
|
* struct L_Bilateral
|
||||||
|
*
|
||||||
|
*
|
||||||
|
* For a tutorial introduction to bilateral filters, which apply a
|
||||||
|
* gaussian blur to smooth parts of the image while preserving edges, see
|
||||||
|
* http://people.csail.mit.edu/sparis/bf_course/slides/03_definition_bf.pdf
|
||||||
|
*
|
||||||
|
* We give an implementation of a bilateral filtering algorithm given in:
|
||||||
|
* "Real-Time O(1) Bilateral Filtering," by Yang, Tan and Ahuja, CVPR 2009
|
||||||
|
* which is at:
|
||||||
|
* http://vision.ai.uiuc.edu/~qyang6/publications/cvpr-09-qingxiong-yang.pdf
|
||||||
|
* This is based on an earlier algorithm by Sylvain Paris and Frédo Durand:
|
||||||
|
* http://people.csail.mit.edu/sparis/publi/2006/eccv/
|
||||||
|
* Paris_06_Fast_Approximation.pdf
|
||||||
|
*
|
||||||
|
* The kernel of the filter is a product of a spatial gaussian and a
|
||||||
|
* monotonically decreasing function of the difference in intensity
|
||||||
|
* between the source pixel and the neighboring pixel. The intensity
|
||||||
|
* part of the filter gives higher influence for pixels with intensities
|
||||||
|
* that are near to the source pixel, and the spatial part of the
|
||||||
|
* filter gives higher weight to pixels that are near the source pixel.
|
||||||
|
* This combination smooths in relatively uniform regions, while
|
||||||
|
* maintaining edges.
|
||||||
|
*
|
||||||
|
* The advantage of the appoach of Yang et al is that it is separable,
|
||||||
|
* so the computation time is linear in the gaussian filter size.
|
||||||
|
* Furthermore, it is possible to do much of the computation as a reduced
|
||||||
|
* scale, which gives a good approximation to the full resolution version
|
||||||
|
* but greatly speeds it up.
|
||||||
|
*
|
||||||
|
* The bilateral filtered value at x is:
|
||||||
|
*
|
||||||
|
* sum[y in N(x)]: spatial(|y - x|) * range(|I(x) - I(y)|) * I(y)
|
||||||
|
* I'(x) = --------------------------------------------------------------
|
||||||
|
* sum[y in N(x)]: spatial(|y - x|) * range(|I(x) - I(y)|)
|
||||||
|
*
|
||||||
|
* where I() is the input image, I'() is the filtered image, N(x) is the
|
||||||
|
* set of pixels around x in the filter support, and spatial() and range()
|
||||||
|
* are gaussian functions:
|
||||||
|
* spatial(x) = exp(-x^2 / (2 * s_s^2))
|
||||||
|
* range(x) = exp(-x^2 / (2 * s_r^2))
|
||||||
|
* and s_s and s_r and the standard deviations of the two gaussians.
|
||||||
|
*
|
||||||
|
* Yang et al use a separable approximation to this, by defining a set
|
||||||
|
* of related but separable functions J(k,x), that we call Principal
|
||||||
|
* Bilateral Components (PBC):
|
||||||
|
*
|
||||||
|
* sum[y in N(x)]: spatial(|y - x|) * range(|k - I(y)|) * I(y)
|
||||||
|
* J(k,x) = -----------------------------------------------------------
|
||||||
|
* sum[y in N(x)]: spatial(|y - x|) * range(|k - I(y)|)
|
||||||
|
*
|
||||||
|
* which are computed quickly for a set of n values k[p], p = 0 ... n-1.
|
||||||
|
* Then each output pixel is found using a linear interpolation:
|
||||||
|
*
|
||||||
|
* I'(x) = (1 - q) * J(k[p],x) + q * J(k[p+1],x)
|
||||||
|
*
|
||||||
|
* where J(k[p],x) and J(k[p+1],x) are PBC for which
|
||||||
|
* k[p] <= I(x) and k[p+1] >= I(x), and
|
||||||
|
* q = (I(x) - k[p]) / (k[p+1] - k[p]).
|
||||||
|
*
|
||||||
|
* We can also subsample I(x), create subsampled versions of J(k,x),
|
||||||
|
* which are then interpolated between for I'(x).
|
||||||
|
*
|
||||||
|
* We generate 'pixsc', by optionally downscaling the input image
|
||||||
|
* (using area mapping by the factor 'reduction'), and then adding
|
||||||
|
* a mirrored border to avoid boundary cases. This is then used
|
||||||
|
* to compute 'ncomps' PBCs.
|
||||||
|
*
|
||||||
|
* The 'spatial_stdev' is also downscaled by 'reduction'. The size
|
||||||
|
* of the 'spatial' array is 4 * (reduced 'spatial_stdev') + 1.
|
||||||
|
* The size of the 'range' array is 256.

|

|
*
|
||||||
|
* <pre>
|
||||||
|
* Data structure to hold arrays and results for generating
|
||||||
|
* horizontal and vertical disparity arrays based on textlines.
|
||||||
|
* Each disparity array is two-dimensional. The vertical disparity
|
||||||
|
* array gives a vertical displacement, relative to the lowest point
|
||||||
|
* in the textlines. The horizontal disparty array gives a horizontal
|
||||||
|
* displacement, relative to the minimum values (for even pages)
|
||||||
|
* or maximum values (for odd pages) of the left and right ends of
|
||||||
|
* full textlines. Horizontal alignment always involves translations
|
||||||
|
* away from the book gutter.
|
||||||
|
*
|
||||||
|
* We have intentionally separated the process of building models
|
||||||
|
* from the rendering process that uses the models. For any page,
|
||||||
|
* the building operation either creates an actual model (that is,
|
||||||
|
* a model with at least the vertical disparity being computed, and
|
||||||
|
* for which the 'success' flag is set) or fails to create a model.
|
||||||
|
* However, at rendering time, a page can have one of two different
|
||||||
|
* types of models.
|
||||||
|
* (1) A valid model is an actual model that meets the rendering
|
||||||
|
* constraints, which are limits on model curvature parameters.
|
||||||
|
* See dewarpaTestForValidModel() for details.
|
||||||
|
* Valid models are identified by dewarpaInsertRefModels(),
|
||||||
|
* which sets the 'vvalid' and 'hvalid' fields. Only valid
|
||||||
|
* models are used for rendering.
|
||||||
|
* (2) A reference model is used by a page that doesn't have
|
||||||
|
* a valid model, but has a nearby valid model of the same
|
||||||
|
* parity (even/odd page) that it can use. The range in pages
|
||||||
|
* to search for a valid model is given by the 'maxdist' field.
|
||||||
|
*
|
||||||
|
* At the rendering stage, vertical and horizontal disparities are
|
||||||
|
* treated differently. It is somewhat more robust to generate
|
||||||
|
* vertical disparity models (VDM) than horizontal disparity
|
||||||
|
* models (HDM). A valid VDM is required for any correction to
|
||||||
|
* be made; if a valid VDM is not available, just use the input
|
||||||
|
* image. Otherwise, assuming it is available, the use of the
|
||||||
|
* HDM is controlled by two fields: 'useboth' and 'check_columns'.
|
||||||
|
* (a) With useboth == 0, we use only the VDM.
|
||||||
|
* (b) With useboth == 1, we require using the VDM and, if a valid
|
||||||
|
* horizontal disparity model (HDM) is available, we also use it.
|
||||||
|
* (c) With check_columns == 1, check for multiple columns and if
|
||||||
|
* true, only use the VDM, even if a valid HDM is available.
|
||||||
|
* Note that 'check_columns' takes precedence over 'useboth'
|
||||||
|
* when there is more than 1 column of text. By default,
|
||||||
|
* check_columns == 0.
|
||||||
|
*
|
||||||
|
* The 'maxdist' parameter is input when the dewarpa is created.
|
||||||
|
* The other rendering parameters have default values given in dewarp1.c.
|
||||||
|
* All parameters used by rendering can be set (or reset) using accessors.
|
||||||
|
*
|
||||||
|
* After dewarping, use of the VDM will cause all points on each
|
||||||
|
* altered curve to have a y-value equal to the minimum. Use of
|
||||||
|
* the HDA will cause the left and right edges of the textlines
|
||||||
|
* to be vertically aligned if they had been typeset flush-left
|
||||||
|
* and flush-right, respectively.
|
||||||
|
*
|
||||||
|
* The sampled disparity arrays are expanded to full resolution,
|
||||||
|
* using linear interpolation, and this is further expanded
|
||||||
|
* by slope continuation to the right and below if the image
|
||||||
|
* is larger than the full resolution disparity arrays. Then
|
||||||
|
* the disparity correction can be applied to the input image.
|
||||||
|
* If the input pix are 2x reduced, the expansion from sampled
|
||||||
|
* to full res uses the product of (sampling) * (redfactor).
|
||||||
|
*
|
||||||
|
* The most accurate results are produced at full resolution, and
|
||||||
|
* this is generally recommended.

|
||||||
|
* *
|
||||||
|
* Messages are printed if the message severity is greater than or equal *

* The compile-time threshold determines which messages are compiled *
|

* into the library for potential printing. Messages below the *
|
||||||
|
* compile-time threshold are omitted and can never be printed. The *
|
||||||
|
* default compile-time threshold is L_SEVERITY_INFO, but this may be *
|
||||||
|
* overridden by defining MINIMUM_SEVERITY to the desired enumeration *
|
||||||
|
* identifier on the compiler command line. Defining NO_CONSOLE_IO on *
|
||||||
|
* the command line is the same as setting MINIMUM_SEVERITY to *
|
||||||
|
* L_SEVERITY_NONE. *
|
||||||
|
* *
|
||||||
|
* The run-time threshold determines which messages are printed during *
|
||||||
|
* library execution. It defaults to the compile-time threshold but *
|
||||||
|
* may be changed either statically by defining DEFAULT_SEVERITY to *
|
||||||
|
* the desired enumeration identifier on the compiler command line, or *

|

|

|
* In effect, the compile-time threshold setting says, "Generate code *

|

|
* example, setting the threshold to L_SEVERITY_WARNING eliminates all
|
||||||
|
* informational messages from the library. With that setting, both
|

|

|

|
||||||
|
* severity to L_SEVERITY_ERROR. In that case, only error messages
|

|
||||||
|
*
|
||||||
|
* This mechanism makes the library smaller and faster, by eliminating
|
||||||
|
* undesired message reporting and the associated run-time overhead for
|
||||||
|
* message threshold checking, because code for messages whose severity
|
||||||
|
* is lower than MINIMUM_SEVERITY won't be generated.
|

|
*
|

|
* A production library might typically permit ERROR messages to be

|
||||||
|
* The actual messages printed (as opposed to generated) would depend
|
||||||
|
* on the current run-time severity threshold.
|
||||||
|
*
|
||||||
|
* This is a complex mechanism and a few examples may help.
|
||||||
|
* (1) No output permitted under any circumstances.
|
||||||
|
* Use: -DNO_CONSOLE_IO or -DMINIMUM_SEVERITY=6
|
||||||
|
* (2) Suppose you want to only allow error messages, and you don't
|
||||||
|
* want to permit info or warning messages at runtime.
|
||||||
|
* Use: -DMINIMUM_SEVERITY=5
|
||||||
|
* (3) Suppose you want to only allow error messages by default,
|
||||||
|
* but you will permit this to be over-ridden at runtime.
|
||||||
|
* Use: -DDEFAULT_SEVERITY=5
|
||||||
|
* and to allow info and warning override:
|
||||||
|
* setMsgSeverity(L_SEVERITY_INFO);

* <pre>
|
||||||
|
* Usage
|
||||||
|
* =====
|
||||||
|
* Messages are of two types.
|
||||||
|
*
|
||||||
|
* (1) The messages
|
||||||
|
* ERROR_INT(a,b,c) : returns l_int32
|
||||||
|
* ERROR_FLOAT(a,b,c) : returns l_float32
|
||||||
|
* ERROR_PTR(a,b,c) : returns void*
|
||||||
|
* are used to return from functions and take a fixed set of parameters:
|
||||||
|
* a : <message string>
|
||||||
|
* b : procName
|
||||||
|
* c : <return value from function>
|
||||||
|
* where procName is the name of the local variable naming the function.
|
||||||
|
*
|
||||||
|
* (2) The purely informational L_* messages
|
||||||
|
* L_ERROR(a,...)
|
||||||
|
* L_WARNING(a,...)
|
||||||
|
* L_INFO(a,...)
|
||||||
|
* do not take a return value, but they take at least two parameters:
|
||||||
|
* a : <message string> with optional format conversions
|
||||||
|
* v1 : procName (this must be included as the first vararg)
|
||||||
|
* v2, ... : optional varargs to match format converters in the message
|
||||||
|
*
|
||||||
|
* To return an error from a function that returns void, use:
|
||||||
|
* L_ERROR(<message string>, procName, [...])
|
||||||
|
* return;
|
||||||
|
*
|
||||||
|
* Implementation details
|
||||||
|
* ======================
|
||||||
|
* Messages are defined with the IF_SEV macro. The first parameter is
|
||||||
|
* the message severity, the second is the function to call if the
|
||||||
|
* message is to be printed, and the third is the return value if the
|
||||||
|
* message is to be suppressed. For example, we might have an
|
||||||
|
* informational message defined as:
|
||||||
|
*
|
||||||
|
* IF_SEV(L_SEVERITY_INFO, fprintf(.......), 0)
|
||||||
|
*
|
||||||
|
* The macro expands into a conditional. Because the first comparison
|
||||||
|
* is between two constants, an optimizing compiler will remove either
|
||||||
|
* the comparison (if it's true) or the entire macro expansion (if it
|
||||||
|
* is false). This means that there is no run-time overhead for
|
||||||
|
* messages whose severity falls below the minimum specified at compile
|
||||||
|
* time, and for others the overhead is one (not two) comparisons.
|
||||||
|
*
|
||||||
|
* The L_nnn() macros below do not return a value, but because the
|
||||||
|
* conditional operator requires one for the false condition, we
|
||||||
|
* specify a void expression.
|
||||||
|
* </pre>

|
||||||
|
* Expandable priority queue configured as a heap for arbitrary void* data
|
||||||
|
*
|
||||||
|
* The L_Heap is used to implement a priority queue. The elements
|
||||||
|
* in the heap are ordered in either increasing or decreasing key value.
|
||||||
|
* The key is a float field 'keyval' that is required to be
|
||||||
|
* contained in the elements of the queue.
|
||||||
|
*
|
||||||
|
* The heap is a simple binary tree with the following constraints:
|
||||||
|
* - the key of each node is >= the keys of the two children
|
||||||
|
* - the tree is complete, meaning that each level (1, 2, 4, ...)
|
||||||
|
* is filled and the last level is filled from left to right
|
||||||
|
*
|
||||||
|
* The tree structure is implicit in the queue array, with the
|
||||||
|
* array elements numbered as a breadth-first search of the tree
|
||||||
|
* from left to right. It is thus guaranteed that the largest
|
||||||
|
* (or smallest) key belongs to the first element in the array.
|
||||||
|
*
|
||||||
|
* Heap sort is used to sort the array. Once an array has been
|
||||||
|
* sorted as a heap, it is convenient to use it as a priority queue,
|
||||||
|
* because the min (or max) elements are always at the root of
|
||||||
|
* the tree (element 0), and once removed, the heap can be
|
||||||
|
* resorted in not more than log[n] steps, where n is the number
|
||||||
|
* of elements on the heap. Likewise, if an arbitrary element is
|
||||||
|
* added to the end of the array A, the sorted heap can be restored
|
||||||
|
* in not more than log[n] steps.
|
||||||
|
*
|
||||||
|
* A L_Heap differs from a L_Queue in that the elements in the former
|
||||||
|
* are sorted by a key. Internally, the array is maintained
|
||||||
|
* as a queue, with a pointer to the end of the array. The
|
||||||
|
* head of the array always remains at array[0]. The array is
|
||||||
|
* maintained (sorted) as a heap. When an item is removed from
|
||||||
|
* the head, the last item takes its place (thus reducing the
|
||||||
|
* array length by 1), and this is followed by array element
|
||||||
|
* swaps to restore the heap property. When an item is added,
|
||||||
|
* it goes at the end of the array, and is swapped up to restore
|
||||||
|
* the heap. If the ptr array is full, adding another item causes
|
||||||
|
* the ptr array size to double.
|
||||||
|
*
|
||||||
|
* For further implementation details, see heap.c.

|
||||||
|
* General features of image I/O in leptonica
|
||||||
|
*
|
||||||
|
* At present, there are 9 file formats for images that can be read
|
||||||
|
* and written:
|
||||||
|
* png (requires libpng, libz)
|
||||||
|
* jpeg (requires libjpeg)
|
||||||
|
* tiff (requires libtiff, libz)
|
||||||
|
* gif (requires libgif)
|
||||||
|
* webp (requires libwebp)
|
||||||
|
* jp2 (requires libopenjp2)
|
||||||
|
* bmp (no library required)
|
||||||
|
* pnm (no library required)
|
||||||
|
* spix (no library required)
|
||||||
|
* Additionally, there are two file formats for writing (only) images:
|
||||||
|
* PostScript (requires libpng, libz, libjpeg, libtiff)
|
||||||
|
* pdf (requires libpng, libz, libjpeg, libtiff)
|
||||||
|
*
|
||||||
|
* For all 9 read/write formats, leptonica provides interconversion
|
||||||
|
* between pix (with raster data) and formatted image data:
|
||||||
|
* Conversion from pix (typically compression):
|
||||||
|
* pixWrite(): pix --> file
|
||||||
|
* pixWriteStream(): pix --> filestream (aka FILE*)
|
||||||
|
* pixWriteMem(): pix --> memory buffer
|
||||||
|
* Conversion to pix (typically decompression):
|
||||||
|
* pixRead(): file --> pix
|
||||||
|
* pixReadStream(): filestream --> pix
|
||||||
|
* pixReadMem(): memory buffer --> pix
|
||||||
|
*
|
||||||
|
* Conversions for which the image data is not compressed are:
|
||||||
|
* * uncompressed tiff (IFF_TIFF)
|
||||||
|
* * bmp
|
||||||
|
* * pnm
|
||||||
|
* * spix (fast serialization that copies the pix raster data)
|
||||||
|
*
|
||||||
|
* The image header (metadata) information can be read from either
|
||||||
|
* the compressed file or a memory buffer, for all 9 formats.

|

* Cell for double-linked lists

*
|

|
* This allows composition of a list of cells with

|

|
* structures hang on the list cell data pointers.
|
||||||
|
*
|

|
* The list is not circular because that would add much
|
||||||
|
* complexity in traversing the list under general
|
||||||
|
* conditions where list cells can be added and removed.
|
||||||
|
* The only disadvantage of not having the head point to
|
||||||
|
* the last cell is that the list must be traversed to
|
||||||
|
* find its tail. However, this traversal is fast, and
|
||||||
|
* the listRemoveFromTail() function updates the tail
|
||||||
|
* so there is no searching overhead with repeated use.
|
||||||
|
*
|
||||||
|
* The list macros are used to run through a list, and their
|
||||||
|
* use is encouraged. They are invoked, e.g., as
|
||||||
|
*

* Expandable pointer queue for arbitrary void* data.
|
||||||
|
*
|
||||||
|
* The L_Queue is a fifo that implements a queue of void* pointers.
|
||||||
|
* It can be used to hold a queue of any type of struct.
|
||||||
|
*
|
||||||
|
* Internally, it maintains two counters:
|
||||||
|
* nhead: location of head (in ptrs) from the beginning
|
||||||
|
* of the array.
|
||||||
|
* nelem: number of ptr elements stored in the queue.
|
||||||
|
*
|
||||||
|
* The element at the head of the queue, which is the next to
|
||||||
|
* be removed, is array[nhead]. The location at the tail of the
|
||||||
|
* queue to which the next element will be added is
|
||||||
|
* array[nhead + nelem].
|
||||||
|
*
|
||||||
|
* As items are added to the queue, nelem increases.
|
||||||
|
* As items are removed, nhead increases and nelem decreases.
|
||||||
|
* Any time the tail reaches the end of the allocated array,
|
||||||
|
* all the pointers are shifted to the left, so that the head
|
||||||
|
* is at the beginning of the array.
|
||||||
|
* If the array becomes more than 3/4 full, it doubles in size.
|
||||||
|
*
|
||||||
|
* The auxiliary stack can be used in a wrapper for re-using
|
||||||
|
* items popped from the queue. It is not made by default.
|
||||||
|
*
|
||||||
|
* For further implementation details, see queue.c.

|

|
*
|
||||||
|
* <pre>
|
||||||
|
* This is a simple utility for training and recognizing individual
|
||||||
|
* machine-printed text characters. It is designed to be adapted
|
||||||
|
* to a particular set of character images; e.g., from a book.
|
||||||
|
*
|
||||||
|
* There are two methods of training the recognizer. In the most
|
||||||
|
* simple, a set of bitmaps has been labeled by some means, such
|
||||||
|
* a generic OCR program. This is input either one template at a time
|
||||||
|
* or as a pixa of templates, to a function that creates a recog.
|
||||||
|
* If in a pixa, the text string label must be embedded in the
|
||||||
|
* text field of each pix.
|
||||||
|
*
|
||||||
|
* If labeled data is not available, we start with a bootstrap
|
||||||
|
* recognizer (BSR) that has labeled data from a variety of sources.
|
||||||
|
* These images are scaled, typically to a fixed height, and then
|
||||||
|
* fed similarly scaled unlabeled images from the source (e.g., book),
|
||||||
|
* and the BSR attempts to identify them. All images that have
|
||||||
|
* a high enough correlation score with one of the templates in the
|
||||||
|
* BSR are emitted in a pixa, which now holds unscaled and labeled
|
||||||
|
* templates from the source. This is the generator for a book adapted
|
||||||
|
* recognizer (BAR).
|
||||||
|
*
|
||||||
|
* The pixa should always be thought of as the primary structure.
|
||||||
|
* It is the generator for the recog, because a recog is built
|
||||||
|
* from a pixa of unscaled images.
|
||||||
|
*
|
||||||
|
* New image templates can be added to a recog as long as it is
|
||||||
|
* in training mode. Once training is finished, to add templates
|
||||||
|
* it is necessary to extract the generating pixa, add templates
|
||||||
|
* to that pixa, and make a new recog. Similarly, we do not
|
||||||
|
* join two recog; instead, we simply join their generating pixa,
|
||||||
|
* and make a recog from that.
|
||||||
|
*
|
||||||
|
* To remove outliers from a pixa of labeled pix, make a recog,
|
||||||
|
* determine the outliers, and generate a new pixa with the
|
||||||
|
* outliers removed. The outliers are determined by building
|
||||||
|
* special templates for each character set that are scaled averages
|
||||||
|
* of the individual templates. Then a correlation score is found
|
||||||
|
* between each template and the averaged templates. There are
|
||||||
|
* two implementations; outliers are determined as either:
|
||||||
|
* (1) a template having a correlation score with its class average
|
||||||
|
* that is below a threshold, or
|
||||||
|
* (2) a template having a correlation score with its class average
|
||||||
|
* that is smaller than the correlation score with the average
|
||||||
|
* of another class.
|
||||||
|
* Outliers are removed from the generating pixa. Scaled averaging
|
||||||
|
* is only performed for determining outliers and for splitting
|
||||||
|
* characters; it is never used in a trained recognizer for identifying
|
||||||
|
* unlabeled samples.
|
||||||
|
*
|
||||||
|
* Two methods using averaged templates are provided for splitting
|
||||||
|
* touching characters:
|
||||||
|
* (1) greedy matching
|
||||||
|
* (2) document image decoding (DID)
|
||||||
|
* The DID method is the default. It is about 5x faster and
|
||||||
|
* possibly more accurate.
|
||||||
|
*
|
||||||
|
* Once a BAR has been made, unlabeled sample images are identified
|
||||||
|
* by finding the individual template in the BAR with highest
|
||||||
|
* correlation. The input images and images in the BAR can be
|
||||||
|
* represented in two ways:
|
||||||
|
* (1) as scanned, binarized to 1 bpp
|
||||||
|
* (2) as a width-normalized outline formed by thinning to a
|
||||||
|
* skeleton and then dilating by a fixed amount.
|
||||||
|
*
|
||||||
|
* The recog can be serialized to file and read back. The serialized
|
||||||
|
* version holds the templates used for correlation (which may have
|
||||||
|
* been modified by scaling and turning into lines from the unscaled
|
||||||
|
* templates), plus, for arbitrary character sets, the UTF8
|
||||||
|
* representation and the lookup table mapping from the character
|
||||||
|
* representation to index.
|
||||||
|
*
|
||||||
|
* Why do we not use averaged templates for recognition?
|
||||||
|
* Letterforms can take on significantly different shapes (eg.,
|
||||||
|
* the letters 'a' and 'g'), and it makes no sense to average these.
|
||||||
|
* The previous version of this utility allowed multiple recognizers
|
||||||
|
* to exist, but this is an unnecessary complication if recognition
|
||||||
|
* is done on all samples instead of on averages.

/*!

||||||
|
* \file regutils.h
|
||||||
|
*
|
||||||
|
* <pre>
|
||||||
|
* Contains this regression test parameter packaging struct
|
||||||
|
* struct L_RegParams
|
||||||
|
*
|
||||||
|
* The regression test utility allows you to write regression tests
|
||||||
|
* that compare results with existing "golden files" and with
|
||||||
|
* compiled in data.
|
||||||
|
*
|
||||||
|
* Regression tests can be called in three ways.
|
||||||
|
* For example, for distance_reg:
|
||||||
|
*
|
||||||
|
* Case 1: distance_reg [compare]
|
||||||
|
* This runs the test against the set of golden files. It
|
||||||
|
* appends to 'outfile.txt' either "SUCCESS" or "FAILURE",
|
||||||
|
* as well as the details of any parts of the test that failed.
|
||||||
|
* It writes to a temporary file stream (fp).
|
||||||
|
* Using 'compare' on the command line is optional.
|
||||||
|
*
|
||||||
|
* Case 2: distance_reg generate
|
||||||
|
* This generates golden files in /tmp for the reg test.
|
||||||
|
*
|
||||||
|
* Case 3: distance_reg display
|
||||||
|
* This runs the test but makes no comparison of the output
|
||||||
|
* against the set of golden files. In addition, this displays
|
||||||
|
* images and plots that are specified in the test under
|
||||||
|
* control of the display variable. Display is enabled only
|
||||||
|
* for this case.
|
||||||
|
*
|
||||||
|
* Regression tests follow the pattern given below. Tests are
|
||||||
|
* automatically numbered sequentially, and it is convenient to
|
||||||
|
* comment each with a number to keep track (for comparison tests
|
||||||
|
* and for debugging). In an actual case, comparisons of pix and
|
||||||
|
* of files can occur in any order. We give a specific order here
|
||||||
|
* for clarity.
|
||||||
|
*
|
||||||
|
* L_REGPARAMS *rp; // holds data required by the test functions
|
||||||
|
*
|
||||||
|
* // Setup variables; optionally open stream
|
||||||
|
* if (regTestSetup(argc, argv, &rp))
|
||||||
|
* return 1;
|
||||||
|
*
|
||||||
|
* // Test pairs of generated pix for identity. This compares
|
||||||
|
* // two pix; no golden file is generated.
|
||||||
|
* regTestComparePix(rp, pix1, pix2); // 0
|
||||||
|
*
|
||||||
|
* // Test pairs of generated pix for similarity. This compares
|
||||||
|
* // two pix; no golden file is generated. The last arg determines
|
||||||
|
* // if stats are to be written to stderr.
|
||||||
|
* regTestCompareSimilarPix(rp, pix1, pix2, 15, 0.001, 0); // 1
|
||||||
|
*
|
||||||
|
* // Generation of <newfile*> outputs and testing for identity
|
||||||
|
* // These files can be anything, of course.
|
||||||
|
* regTestCheckFile(rp, <newfile0>); // 2
|
||||||
|
* regTestCheckFile(rp, <newfile1>); // 3
|
||||||
|
*
|
||||||
|
* // Test pairs of output golden files for identity. Here we
|
||||||
|
* // are comparing golden files 2 and 3.
|
||||||
|
* regTestCompareFiles(rp, 2, 3); // 4
|
||||||
|
*
|
||||||
|
* // "Write and check". This writes a pix using a canonical
|
||||||
|
* // formulation for the local filename and either:
|
||||||
|
* // case 1: generates a golden file
|
||||||
|
* // case 2: compares the local file with a golden file
|
||||||
|
* // case 3: generates local files and displays
|
||||||
|
* // Here we write the pix compressed with png and jpeg, respectively;
|
||||||
|
* // Then check against the golden file. The internal %index
|
||||||
|
* // is incremented; it is embedded in the local filename and,
|
||||||
|
* // if generating, in the golden file as well.
|
||||||
|
* regTestWritePixAndCheck(rp, pix1, IFF_PNG); // 5
|
||||||
|
* regTestWritePixAndCheck(rp, pix2, IFF_JFIF_JPEG); // 6

||||||

GOALS
|
||||||
|
|
||||||
|
o Enable a "pull" interface. The application that uses libcurl decides where
|
||||||
|
and when to ask libcurl to get/send data.
|
||||||
|
|
||||||
|
o Enable multiple simultaneous transfers in the same thread without making it
|
||||||
|
complicated for the application.
|
||||||
|
|
||||||
|
o Enable the application to select() on its own file descriptors and curl's
|
||||||
|
file descriptors simultaneous easily.

||||||
