* *Experimental* *only*
|
||||
*
|
||||
* The auto-hinter provides various script modules to hint glyphs.
|
||||
* Examples of supported scripts are Latin or CJK. Before a glyph is
|
||||
* auto-hinted, the Unicode character map of the font gets examined, and
|
||||
* the script is then determined based on Unicode character ranges, see
|
||||
* below.
|
||||
*
|
||||
* OpenType fonts, however, often provide much more glyphs than
|
||||
* character codes (small caps, superscripts, ligatures, swashes, etc.),
|
||||
* to be controlled by so-called `features'. Handling OpenType features
|
||||
* can be quite complicated and thus needs a separate library on top of
|
||||
* FreeType.
|
||||
*
|
||||
* The mapping between glyph indices and scripts (in the auto-hinter
|
||||
* sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
|
||||
* array with `num_glyphs' elements, as found in the font's @FT_Face
|
||||
* structure. The `glyph-to-script-map' property returns a pointer to
|
||||
* this array, which can be modified as needed. Note that the
|
||||
* modification should happen before the first glyph gets processed by
|
||||
* the auto-hinter so that the global analysis of the font shapes
|
||||
* actually uses the modified mapping.
|
||||
*
|
||||
* The following example code demonstrates how to access it (omitting
|
||||
* the error handling).

|

*
|
||||
* Stem darkening emboldens glyphs at smaller sizes to make them more
|
||||
* readable on common low-DPI screens when using linear alpha blending
|
||||
* and gamma correction, see @FT_Render_Glyph. When not using linear
|
||||
* alpha blending and gamma correction, glyphs will appear heavy and
|
||||
* fuzzy!
|
||||
*
|
||||
* Gamma correction essentially lightens fonts since shades of grey are
|
||||
* shifted to higher pixel values (=~higher brightness) to match the
|
||||
* original intention to the reality of our screens. The side-effect is
|
||||
* that glyphs `thin out'. Mac OS~X and Adobe's proprietary font
|
||||
* rendering library implement a counter-measure: stem darkening at
|
||||
* smaller sizes where shades of gray dominate. By emboldening a glyph
|
||||
* slightly in relation to its pixel size, individual pixels get higher
|
||||
* coverage of filled-in outlines and are therefore `blacker'. This
|
||||
* counteracts the `thinning out' of glyphs, making text remain readable
|
||||
* at smaller sizes. All glyphs that pass through the auto-hinter will
|
||||
* be emboldened unless this property is set to TRUE.
|
||||
*
|
||||
* See the description of the CFF driver for algorithmic details. Total
|
||||
* consistency with the CFF driver is currently not achieved because the
|
||||
* emboldening method differs and glyphs must be scaled down on the
|
||||
* Y-axis to keep outline points inside their precomputed blue zones.
|
||||
* The smaller the size (especially 9ppem and down), the higher the loss
|
||||
* of emboldening versus the CFF driver.

* The CFF driver
|

*
|
||||
* @abstract:
|
||||
* Controlling the CFF driver module.
|
||||
*
|
||||
* @description:
|
||||
* While FreeType's CFF driver doesn't expose API functions by itself,
|
||||
* it is possible to control its behaviour with @FT_Property_Set and
|
||||
* @FT_Property_Get. The list below gives the available properties
|
||||
* together with the necessary macros and structures.
|
||||
*
|
||||
* The CFF driver's module name is `cff'.
|
||||
*
|
||||
* *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
|
||||
*
|
||||
* The rasterizer is positioning horizontal features (e.g., ascender
|
||||
* height & x-height, or crossbars) on the pixel grid and minimizing the
|
||||
* amount of antialiasing applied to them, while placing vertical
|
||||
* features (vertical stems) on the pixel grid without hinting, thus
|
||||
* representing the stem position and weight accurately. Sometimes the
|
||||
* vertical stems may be only partially black. In this context,
|
||||
* `antialiasing' means that stems are not positioned exactly on pixel
|
||||
* borders, causing a fuzzy appearance.
|
||||
*
|
||||
* There are two principles behind this approach.
|
||||
*
|
||||
* 1) No hinting in the horizontal direction: Unlike `superhinted'
|
||||
* TrueType, which changes glyph widths to accommodate regular
|
||||
* inter-glyph spacing, Adobe's approach is `faithful to the design' in
|
||||
* representing both the glyph width and the inter-glyph spacing
|
||||
* designed for the font. This makes the screen display as close as it
|
||||
* can be to the result one would get with infinite resolution, while
|
||||
* preserving what is considered the key characteristics of each glyph.
|
||||
* Note that the distances between unhinted and grid-fitted positions at
|
||||
* small sizes are comparable to kerning values and thus would be
|
||||
* noticeable (and distracting) while reading if hinting were applied.
|
||||
*
|
||||
* One of the reasons to not hint horizontally is antialiasing for LCD
|
||||
* screens: The pixel geometry of modern displays supplies three
|
||||
* vertical sub-pixels as the eye moves horizontally across each visible
|
||||
* pixel. On devices where we can be certain this characteristic is
|
||||
* present a rasterizer can take advantage of the sub-pixels to add
|
||||
* increments of weight. In Western writing systems this turns out to
|
||||
* be the more critical direction anyway; the weights and spacing of
|
||||
* vertical stems (see above) are central to Armenian, Cyrillic, Greek,
|
||||
* and Latin type designs. Even when the rasterizer uses greyscale
|
||||
* antialiasing instead of color (a necessary compromise when one
|
||||
* doesn't know the screen characteristics), the unhinted vertical
|
||||
* features preserve the design's weight and spacing much better than
|
||||
* aliased type would.
|
||||
*
|
||||
* 2) Aligment in the vertical direction: Weights and spacing along the
|
||||
* y~axis are less critical; what is much more important is the visual
|
||||
* alignment of related features (like cap-height and x-height). The
|
||||
* sense of alignment for these is enhanced by the sharpness of grid-fit
|
||||
* edges, while the cruder vertical resolution (full pixels instead of
|
||||
* 1/3 pixels) is less of a problem.
|
||||
*
|
||||
* On the technical side, horizontal alignment zones for ascender,
|
||||
* x-height, and other important height values (traditionally called
|
||||
* `blue zones') as defined in the font are positioned independently,
|
||||
* each being rounded to the nearest pixel edge, taking care of
|
||||
* overshoot suppression at small sizes, stem darkening, and scaling.
|
||||
*
|
||||
* Hstems (this is, hint values defined in the font to help align
|
||||
* horizontal features) that fall within a blue zone are said to be
|
||||
* `captured' and are aligned to that zone. Uncaptured stems are moved
|
||||
* in one of four ways, top edge up or down, bottom edge up or down.
|
||||
* Unless there are conflicting hstems, the smallest movement is taken
|
||||
* to minimize distortion.

|
||||
* LCD Filtering
|
||||
*
|
||||
* @abstract:
|
||||
* Reduce color fringes of subpixel-rendered bitmaps.
|
||||
*
|
||||
* @description:
|
||||
* Subpixel 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. Since these
|
||||
* subpixels are color pixels, using them unfiltered creates severe
|
||||
* color fringes. Use the @FT_Library_SetLcdFilter API to specify a
|
||||
* low-pass filter, which is then applied to subpixel-rendered bitmaps
|
||||
* generated through @FT_Render_Glyph. The filter sacrifices some of
|
||||
* the higher resolution to reduce color fringes, making the glyph image
|
||||
* slightly blurrier. Positional improvements will remain.
|
||||
*
|
||||
* Note that no filter is active by default, and that this function is
|
||||
* *not* implemented in default builds of the library. You need to
|
||||
* #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your `ftoption.h' file
|
||||
* in order to activate it and explicitly call @FT_Library_SetLcdFilter
|
||||
* to enable it.
|
||||
*
|
||||
* A filter should have two properties:
|
||||
*
|
||||
* 1) It should be normalized, meaning the sum of the 5~components
|
||||
* should be 256 (0x100). It is possible to go above or under this
|
||||
* target sum, however: going under means tossing out contrast, going
|
||||
* over means invoking clamping and thereby non-linearities that
|
||||
* increase contrast somewhat at the expense of greater distortion
|
||||
* and color-fringing. Contrast is better enhanced through stem
|
||||
* darkening.
|
||||
*
|
||||
* 2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
|
||||
* where a~+ b~=~c. It distributes the computed coverage for one
|
||||
* subpixel to all subpixels equally, sacrificing some won resolution
|
||||
* but drastically reducing color-fringing. Positioning improvements
|
||||
* remain! Note that color-fringing can only really be minimized
|
||||
* when using a color-balanced filter and alpha-blending the glyph
|
||||
* onto a surface in linear space; see @FT_Render_Glyph.
|
||||
*
|
||||
* Regarding the form, a filter can be a `boxy' filter or a `beveled'
|
||||
* filter. Boxy filters are sharper but are less forgiving of non-ideal
|
||||
* gamma curves of a screen (viewing angles!), beveled filters are
|
||||
* fuzzier but more tolerant.
|
||||
*
|
||||
* Examples:
|
||||
*
|
||||
* - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
|
||||
* normalized.
|
||||
*
|
||||
* - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
|
||||
* normalized.
|
||||
*
|
||||
* - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
|
||||
* balanced.
|
||||
*
|
||||
* - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
|
||||
* balanced.
|
||||
*
|
||||
* - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
|
||||
* balanced.
|
||||
*
|
||||
* - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
|
||||
* balanced.
|
||||
*
|
||||
* The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
|
||||
* @FT_Load_Glyph, and @FT_Load_Char. It does _not_ affect the output
|
||||
* of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
|
||||
*
|
||||
* If this feature is activated, the dimensions of LCD glyph bitmaps are
|
||||
* 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 3~subpixels to the left, and
|
||||
* 3~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.
|
||||
*
|
||||
* It is important to understand that linear alpha blending and gamma
|
||||
* correction is critical for correctly rendering glyphs onto surfaces
|
||||
* without artifacts and even more critical when subpixel rendering is
|
||||
* involved.
|
||||
*
|

|
||||
* FT_LcdFilter
|
||||
*
|
||||
* @description:
|
||||
* A list of values to identify various types of LCD filters.
|
||||
*
|
||||
* @values:
|
||||
* FT_LCD_FILTER_NONE ::
|
||||
* Do not perform filtering. When used with subpixel rendering, this
|
||||
* results in sometimes severe color fringes.
|
||||
*
|
||||
* FT_LCD_FILTER_DEFAULT ::
|
||||
* The default filter reduces color fringes considerably, at the cost
|
||||
* of a slight blurriness in the output.
|
||||
*
|
||||
* It is a beveled, normalized, and color-balanced five-tap filter
|
||||
* that is more forgiving to screens with non-ideal gamma curves and
|
||||
* viewing angles. Note that while color-fringing is reduced, it can
|
||||
* only be minimized by using linear alpha blending and gamma
|
||||
* correction to render glyphs onto surfaces. The default filter
|
||||
* weights are [0x08 0x4D 0x56 0x4D 0x08].
|
||||
*
|
||||
* FT_LCD_FILTER_LIGHT ::
|
||||
* The light filter is a variant that is sharper at the cost of
|
||||
* slightly more color fringes than the default one.
|
||||
*
|
||||
* It is a boxy, normalized, and color-balanced three-tap filter that
|
||||
* is less forgiving to screens with non-ideal gamma curves and
|
||||
* viewing angles. This filter works best when the rendering system
|
||||
* uses linear alpha blending and gamma correction to render glyphs
|
||||
* onto surfaces. The light filter weights are
|
||||
* [0x00 0x55 0x56 0x55 0x00].
|
||||
*
|
||||
* FT_LCD_FILTER_LEGACY ::
|
||||
* This filter corresponds to the original libXft color filter. It
|
||||
* provides high contrast output but can exhibit really bad color
|
||||
* fringes if glyphs are not extremely well hinted to the pixel grid.
|
||||
* In other words, it only works well if the TrueType bytecode
|
||||
* interpreter is enabled *and* high-quality hinted fonts are used.
|
||||
*
|
||||
* This filter is only provided for comparison purposes, and might be
|
||||
* disabled or stay unsupported in the future.
|
||||
*
|
||||
* FT_LCD_FILTER_LEGACY1 ::
|
||||
* For historical reasons, the FontConfig library returns a different
|
||||
* enumeration value for legacy LCD filtering. To make code work that
|
||||
* (incorrectly) forwards FontConfig's enumeration value to
|
||||
* @FT_Library_SetLcdFilter without proper mapping, it is thus easiest
|
||||
* to have another enumeration value, which is completely equal to
|
||||
* `FT_LCD_FILTER_LEGACY'.
|
||||
*
|
||||
* @since:
|
||||
* 2.3.0 (`FT_LCD_FILTER_LEGACY1' since 2.6.2)

* The TrueType driver
|

*
|
||||
* @abstract:
|
||||
* Controlling the TrueType driver module.
|
||||
*
|
||||
* @description:
|
||||
* While FreeType's TrueType driver doesn't expose API functions by
|
||||
* itself, it is possible to control its behaviour with @FT_Property_Set
|
||||
* and @FT_Property_Get. The following lists the available properties
|
||||
* together with the necessary macros and structures.
|
||||
*
|
||||
* The TrueType driver's module name is `truetype'.
|
||||
*
|
||||
* We start with a list of definitions, kindly provided by Greg
|
||||
* Hitchcock.
|
||||
*
|
||||
* _Bi-Level_ _Rendering_
|
||||
*
|
||||
* Monochromatic rendering, exclusively used in the early days of
|
||||
* TrueType by both Apple and Microsoft. Microsoft's GDI interface
|
||||
* supported hinting of the right-side bearing point, such that the
|
||||
* advance width could be non-linear. Most often this was done to
|
||||
* achieve some level of glyph symmetry. To enable reasonable
|
||||
* performance (e.g., not having to run hinting on all glyphs just to
|
||||
* get the widths) there was a bit in the head table indicating if the
|
||||
* side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
|
||||
* cache hinting widths across multiple sizes and device aspect ratios.
|
||||
*
|
||||
* _Font_ _Smoothing_
|
||||
*
|
||||
* Microsoft's GDI implementation of anti-aliasing. Not traditional
|
||||
* anti-aliasing as the outlines were hinted before the sampling. The
|
||||
* widths matched the bi-level rendering.
|
||||
*
|
||||
* _ClearType_ _Rendering_
|
||||
*
|
||||
* Technique that uses physical subpixels to improve rendering on LCD
|
||||
* (and other) displays. Because of the higher resolution, many methods
|
||||
* of improving symmetry in glyphs through hinting the right-side
|
||||
* bearing were no longer necessary. This lead to what GDI calls
|
||||
* `natural widths' ClearType, see
|
||||
* http://www.beatstamm.com/typography/RTRCh4.htm#Sec21. Since hinting
|
||||
* has extra resolution, most non-linearity went away, but it is still
|
||||
* possible for hints to change the advance widths in this mode.
|
||||
*
|
||||
* _ClearType_ _Compatible_ _Widths_
|
||||
*
|
||||
* One of the earliest challenges with ClearType was allowing the
|
||||
* implementation in GDI to be selected without requiring all UI and
|
||||
* documents to reflow. To address this, a compatible method of
|
||||
* rendering ClearType was added where the font hints are executed once
|
||||
* to determine the width in bi-level rendering, and then re-run in
|
||||
* ClearType, with the difference in widths being absorbed in the font
|
||||
* hints for ClearType (mostly in the white space of hints); see
|
||||
* http://www.beatstamm.com/typography/RTRCh4.htm#Sec20. Somewhat by
|
||||
* definition, compatible width ClearType allows for non-linear widths,
|
||||
* but only when the bi-level version has non-linear widths.
|
||||
*
|
||||
* _ClearType_ _Subpixel_ _Positioning_
|
||||
*
|
||||
* One of the nice benefits of ClearType is the ability to more crisply
|
||||
* display fractional widths; unfortunately, the GDI model of integer
|
||||
* bitmaps did not support this. However, the WPF and Direct Write
|
||||
* frameworks do support fractional widths. DWrite calls this `natural
|
||||
* mode', not to be confused with GDI's `natural widths'. Subpixel
|
||||
* positioning, in the current implementation of Direct Write,
|
||||
* unfortunately does not support hinted advance widths, see
|
||||
* http://www.beatstamm.com/typography/RTRCh4.htm#Sec22. Note that the
|
||||
* TrueType interpreter fully allows the advance width to be adjusted in
|
||||
* this mode, just the DWrite client will ignore those changes.
|
||||
*
|
||||
* _ClearType_ _Backwards_ _Compatibility_
|
||||
*
|
||||
* This is a set of exceptions made in the TrueType interpreter to
|
||||
* minimize hinting techniques that were problematic with the extra
|
||||
* resolution of ClearType; see
|
||||
* http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
|
||||
* http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
|
||||
* This technique is not to be confused with ClearType compatible
|
||||
* widths. ClearType backwards compatibility has no direct impact on
|
||||
* changing advance widths, but there might be an indirect impact on
|
||||
* disabling some deltas. This could be worked around in backwards
|
||||
* compatibility mode.
|
||||
*
|
||||
* _Native_ _ClearType_ _Mode_
|
||||
*
|
||||
* (Not to be confused with `natural widths'.) This mode removes all
|
||||
* the exceptions in the TrueType interpreter when running with
|
||||
* ClearType. Any issues on widths would still apply, though.

|

* @description:
|
||||
* Currently, two versions are available, representing the bytecode
|
||||
* interpreter with and without subpixel hinting support,
|
||||
* respectively. The default is subpixel support if
|
||||
* TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel
|
||||
* support otherwise (since it isn't available then).
|
||||
*
|
||||
* If subpixel hinting is on, many TrueType bytecode instructions behave
|
||||
* differently compared to B/W or grayscale rendering (except if `native
|
||||
* ClearType' is selected by the font). The main idea is to render at a
|
||||
* much increased horizontal resolution, then sampling down the created
|
||||
* output to subpixel precision. However, many older fonts are not
|
||||
* suited to this and must be specially taken care of by applying
|
||||
* (hardcoded) font-specific tweaks.
|
||||
*
|
||||
* Details on subpixel hinting and some of the necessary tweaks can be
|

|
||||
* @enum:
|
||||
* TT_INTERPRETER_VERSION_XXX
|
||||
*
|
||||
* @description:
|
||||
* A list of constants used for the @interpreter-version property to
|
||||
* select the hinting engine for Truetype fonts.
|
||||
*
|
||||
* The numeric value in the constant names represents the version
|
||||
* number as returned by the `GETINFO' bytecode instruction.
|
||||
*
|
||||
* @values:
|
||||
* TT_INTERPRETER_VERSION_35 ::
|
||||
* Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
|
||||
* Windows~98; only grayscale and B/W rasterizing is supported.
|
||||
*
|
||||
* TT_INTERPRETER_VERSION_38 ::
|
||||
* Version~38 corresponds to MS rasterizer v.1.9; it is roughly
|
||||
* equivalent to the hinting provided by DirectWrite ClearType (as
|
||||
* can be found, for example, in the Internet Explorer~9 running on
|
||||
* Windows~7).
|
||||
*
|
||||
* @note:
|
||||
* This property controls the behaviour of the bytecode interpreter
|
||||
* and thus how outlines get hinted. It does *not* control how glyph
|
||||
* get rasterized! In particular, it does not control subpixel color
|
||||
* filtering.
|
||||
*
|
||||
* If FreeType has not been compiled with configuration option
|
||||
* FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 causes an
|
||||
* `FT_Err_Unimplemented_Feature' error.
|
||||
*
|
||||
* Depending on the graphics framework, Microsoft uses different
|
||||
* bytecode and rendering engines. As a consequence, the version
|
||||
* numbers returned by a call to the `GETINFO' bytecode instruction are
|
||||
* more convoluted than desired.
|
||||
*
|
||||
* Here are two tables that try to shed some light on the possible
|
||||
* values for the MS rasterizer engine, together with the additional
|
||||
* features introduced by it.

|
||||
* GDI+ old (before Vista)
|
||||
* 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType,
|
||||
* WPF Y-direction ClearType,
|
||||
* additional error checking
|
||||
* 39 DWrite (before Win 8) v2.0 subpixel ClearType flags

|
||||
* DWrite (Win 8) in GETINFO opcode,
|
||||
* Gray ClearType
|
||||
* }
|
||||
*
|
||||
* The `version' field gives a rough orientation only, since some
|
||||
* applications provided certain features much earlier (as an example,
|
||||
* Microsoft Reader used subpixel and Y-direction ClearType already in
|
||||
* Windows 2000). Similarly, updates to a given framework might include
|
||||
* improved hinting support.

|
||||
* --------------------------------------------------------------
|
||||
* v1.0 normal normal B/W B/W bi-level
|
||||
* v1.6 high high gray gray grayscale
|
||||
* v1.8 high normal color-filter B/W (GDI) ClearType
|
||||
* v1.9 high high color-filter gray Color ClearType
|
||||
* v2.1 high normal gray B/W Gray ClearType
|
||||
* v2.1 high high gray gray Gray ClearType
|
||||
* }
|
||||
*
|
||||
* Color and Gray ClearType are the two available variants of
|
||||
* `Y-direction ClearType', meaning grayscale rasterization along the
|
||||
* Y-direction; the name used in the TrueType specification for this
|
||||
* feature is `symmetric smoothing'. `Classic ClearType' is the
|
||||
* original algorithm used before introducing a modified version in
|
||||
* Win~XP. Another name for v1.6's grayscale rendering is `font
|
||||
* smoothing', and `Color ClearType' is sometimes also called `DWrite
|
||||
* ClearType'. To differentiate between today's Color ClearType and the
|
||||
* earlier ClearType variant with B/W rendering along the vertical axis,
|
||||
* the latter is sometimes called `GDI ClearType'.
|
||||
*
|
||||
* `Normal' and `high' sampling describe the (virtual) resolution to
|
||||
* access the rasterized outline after the hinting process. `Normal'
|
||||
* means 1 sample per grid line (i.e., B/W). In the current Microsoft
|
||||
* implementation, `high' means an extra virtual resolution of 16x16 (or
|
||||
* 16x1) grid lines per pixel for bytecode instructions like `MIRP'.
|
||||
* After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
|
||||
* lines for color filtering if Color ClearType is activated.
|
||||
*
|
||||
* Note that `Gray ClearType' is essentially the same as v1.6's
|
||||
* grayscale rendering. However, the GETINFO instruction handles it
|
||||
* differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
|
||||
* returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
|
||||
* and~19 (Gray ClearType). Also, this mode respects bits 2 and~3 for
|
||||
* the version~1 gasp table exclusively (like Color ClearType), while
|
||||
* v1.6 only respects the values of version~0 (bits 0 and~1).
|
||||
*
|
||||
* FreeType doesn't provide all capabilities of the most recent
|
||||
* ClearType incarnation, thus we identify our subpixel support as
|
||||
* version~38.

* A list of valid values for the `charset' byte in

* encodings (except for cp1361) can be found at

* MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
|
||||
*
|
||||
* @values:
|
||||
* FT_WinFNT_ID_DEFAULT ::
|
||||
* This is used for font enumeration and font creation as a
|
||||
* `don't care' value. Valid font files don't contain this value.
|
||||
* When querying for information about the character set of the font
|
||||
* that is currently selected into a specified device context, this
|
||||
* return value (of the related Windows API) simply denotes failure.
|
||||
*
|
||||
* FT_WinFNT_ID_SYMBOL ::
|
||||
* There is no known mapping table available.
|
||||
*
|

* FT_WinFNT_ID_MAC ::
|
||||
* Mac Roman encoding.
|
||||
*
|
||||
* FT_WinFNT_ID_OEM ::
|
||||
* From Michael Pöttgen <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://msdn.microsoft.com/en-us/goglobal/bb964655,
|
||||
*
|
||||
* 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.
|
||||
*
|

* FT_WinFNT_ID_CP874 ::
|

|
||||
*
|
||||
* FT_WinFNT_ID_CP949 ::

|

*
|

* @description:
|
||||
* Retrieve the value for the supplied key from a PostScript font.
|
||||
*
|
||||
* @input:
|
||||
* face ::
|
||||
* PostScript face handle.
|
||||
*
|
||||
* key ::
|
||||
* An enumeration value representing the dictionary key to retrieve.
|
||||
*
|
||||
* idx ::
|
||||
* For array values, this specifies the index to be returned.
|
||||
*
|
||||
* value ::
|
||||
* A pointer to memory into which to write the value.
|
||||
*
|
||||
* valen_len ::
|
||||
* The size, in bytes, of the memory supplied for the value.
|
||||
*
|
||||
* @output:
|
||||
* value ::
|
||||
* The value matching the above key, if it exists.
|
||||
*
|
||||
* @return:
|
||||
* The amount of memory (in bytes) required to hold the requested
|
||||
* value (if it exists, -1 otherwise).
|
||||
*
|
||||
* @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.
|
||||
*
|
||||
* If the font's format is not PostScript-based, this function returns
|
||||
* the `FT_Err_Invalid_Argument' error code.

|
||||
writes out PNG/BMP/TGA images to C stdio - Sean Barrett 2010-2015
|
||||
no warranty implied; use at your own risk
|
||||
|
||||
Before #including,
|
||||
|
||||
#define STB_IMAGE_WRITE_IMPLEMENTATION
|
||||
|
||||
in the file that you want to have the implementation.
|
||||
|
||||
Will probably not work correctly with strict-aliasing optimizations.
|
||||
|
||||
ABOUT:
|
||||
|
||||
This header file is a library for writing images to C stdio. It could be
|
||||
adapted to write to memory or a general streaming interface; let me know.
|
||||
|
||||
The PNG output is not optimal; it is 20-50% larger than the file
|
||||
written by a decent optimizing implementation. This library is designed
|
||||
for source code compactness and simplicity, not optimal image file size
|
||||
or run-time performance.
|
||||
|
||||
BUILDING:
|
||||
|
||||
You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
|
||||
You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
|
||||
malloc,realloc,free.
|
||||
You can define STBIW_MEMMOVE() to replace memmove()
|
||||
|
||||
USAGE:
|
||||
|
||||
There are four functions, one for each image file format:
|
||||
|
||||
int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
|
||||
int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
|
||||
int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
|
||||
int stbi_write_hdr(char const *filename, int w, int h, int comp, const void *data);
|
||||
|
||||
There are also four equivalent functions that use an arbitrary write function. You are
|
||||
expected to open/close your file-equivalent before and after calling these:
|
||||
|
||||
int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes);
|
||||
int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
|
||||
int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
|
||||
int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
|
||||
|
||||
where the callback is:
|
||||
void stbi_write_func(void *context, void *data, int size);
|
||||
|
||||
You can define STBI_WRITE_NO_STDIO to disable the file variant of these
|
||||
functions, so the library will not use stdio.h at all. However, this will
|
||||
also disable HDR writing, because it requires stdio for formatted output.
|
||||
|
||||
Each function returns 0 on failure and non-0 on success.
|
||||
|
||||
The functions create an image file defined by the parameters. The image
|
||||
is a rectangle of pixels stored from left-to-right, top-to-bottom.
|
||||
Each pixel contains 'comp' channels of data stored interleaved with 8-bits
|
||||
per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
|
||||
monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
|
||||
The *data pointer points to the first byte of the top-left-most pixel.
|
||||
For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
|
||||
a row of pixels to the first byte of the next row of pixels.
|
||||
|
||||
PNG creates output files with the same number of components as the input.
|
||||
The BMP format expands Y to RGB in the file format and does not
|
||||
output alpha.
|
||||
|
||||
PNG supports writing rectangles of data even when the bytes storing rows of
|
||||
data are not consecutive in memory (e.g. sub-rectangles of a larger image),
|
||||
by supplying the stride between the beginning of adjacent rows. The other
|
||||
formats do not. (Thus you cannot write a native-format BMP through the BMP
|
||||
writer, both because it is in BGR order and because it may have padding
|
||||
at the end of the line.)
|
||||
|
||||
HDR expects linear float data. Since the format is always 32-bit rgb(e)
|
||||
data, alpha (if provided) is discarded, and for monochrome data it is
|
||||
replicated across all three channels.
|
||||
|
||||
TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
|
||||
data, set the global variable 'stbi_write_tga_with_rle' to 0.
