Spatial indexes are data structures that are used to accelerate collision detection
|
||||||
|
and spatial queries. Chipmunk provides a number of spatial index algorithms to pick from
|
||||||
|
and they are programmed in a generic way so that you can use them for holding more than
|
||||||
|
just cpShape structs.
|
||||||
|
|
||||||
|
It works by using @c void pointers to the objects you add and using a callback to ask your code
|
||||||
|
for bounding boxes when it needs them. Several types of queries can be performed an index as well
|
||||||
|
as reindexing and full collision information. All communication to the spatial indexes is performed
|
||||||
|
through callback functions.
|
||||||
|
|
||||||
|
Spatial indexes should be treated as opaque structs.
|
||||||
|
This meanns you shouldn't be reading any of the struct fields.

* 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).

|
* Since warping is a global property of the auto-hinter it is best to

|
* change its value before rendering any face. Otherwise, you should

||||||
|
* 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.

|

|
* @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.

|
||||||
|
*
|

|
* To enable this mode, you must use @FT_Open_Face, passing an
|
||||||
|
* @FT_Parameter with the @FT_PARAM_TAG_INCREMENTAL tag and an
|

|
* @FT_Incremental_Interface value. See the comments for

|
||||||
|
* 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.
|
||||||
|
*
|
||||||
|
* Each of the 3~alpha values (subpixels) is 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. The
|
||||||
|
* distribution of density values by the color-balanced filter assumes
|
||||||
|
* alpha blending is done in linear space; only then color artifacts
|
||||||
|
* cancel out.

|

|
*
|

|
* @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)

|

|
* stream :: The target embedding stream.

* source :: The source stream.

* FreeType error code. 0~means success.
|

|
*
|
||||||
|
* @note:
|
||||||
|
* The source stream must be opened _before_ calling this function.
|
||||||
|
*
|
||||||
|
* Calling the internal function `FT_Stream_Close' on the new stream will
|
||||||
|
* *not* call `FT_Stream_Close' on the source stream. None of the stream
|
||||||
|
* objects will be released to the heap.
|
||||||
|
*
|
||||||
|
* The stream implementation is very basic and resets the decompression
|
||||||
|
* process each time seeking backwards is needed within the stream
|
||||||
|
*
|
||||||
|
* In certain builds of the library, LZW compression recognition is
|
||||||
|
* automatically handled when calling @FT_New_Face or @FT_Open_Face.
|
||||||
|
* This means that if no font driver is capable of handling the raw
|
||||||
|
* compressed file, the library will try to open a LZW stream from it
|
||||||
|
* and re-open the face with it.
|
||||||
|
*
|
||||||
|
* This function may return `FT_Err_Unimplemented_Feature' if your build
|
||||||
|
* of FreeType was not compiled with LZW support.

|

* 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
|
||||||
|
* found in Greg Hitchcock's whitepaper at

|
||||||
|
*
|
||||||
|
* 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
|

* 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
|

|
||||||
|

|
* Depending on the graphics framework, Microsoft uses different

|
* numbers returned by a call to the `GETINFO' bytecode instruction are
|
||||||
|
* more convoluted than desired.

|

|
||||||

|
||||||
|

|

|
* 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.

|

|
||||||
|
* @description:
|
||||||
|
* A list of valid values for the `charset' byte in
|
||||||
|
* @FT_WinFNT_HeaderRec. Exact mapping tables for the various cpXXXX
|
||||||
|
* encodings (except for cp1361) can be found at
|
||||||
|
* ftp://ftp.unicode.org/Public in the MAPPINGS/VENDORS/MICSFT/WINDOWS
|
||||||
|
* subdirectory. cp1361 is roughly a superset of
|
||||||
|
* 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 ::

* @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.

|

|
* }
|
||||||
|
*
|
||||||
|
* Note that structures like @TT_Header or @TT_OS2 can't be used with
|
||||||
|
* this function; they are limited to @FT_Get_Sfnt_Table. Reason is that
|
||||||
|
* those structures depend on the processor architecture, with varying
|

|
* size (e.g. 32bit vs. 64bit) or order (big endian vs. little endian).

/* Function calling conventions.
|
||||||
|
* =============================
|
||||||
|
* Normally it is not necessary to specify to the compiler how to call
|
||||||
|
* a function - it just does it - however on x86 systems derived from
|
||||||
|
* Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
|
||||||
|
* and some others) there are multiple ways to call a function and the
|
||||||
|
* default can be changed on the compiler command line. For this reason
|
||||||
|
* libpng specifies the calling convention of every exported function and
|
||||||
|
* every function called via a user supplied function pointer. This is
|
||||||
|
* done in this file by defining the following macros:
|
||||||
|
*
|
||||||
|
* PNGAPI Calling convention for exported functions.
|
||||||
|
* PNGCBAPI Calling convention for user provided (callback) functions.
|
||||||
|
* PNGCAPI Calling convention used by the ANSI-C library (required
|
||||||
|
* for longjmp callbacks and sometimes used internally to
|
||||||
|
* specify the calling convention for zlib).
|
||||||
|
*
|
||||||
|
* These macros should never be overridden. If it is necessary to
|
||||||
|
* change calling convention in a private build this can be done
|
||||||
|
* by setting PNG_API_RULE (which defaults to 0) to one of the values
|
||||||
|
* below to select the correct 'API' variants.
|
||||||
|
*
|
||||||
|
* PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
|
||||||
|
* This is correct in every known environment.
|
||||||
|
* PNG_API_RULE=1 Use the operating system convention for PNGAPI and
|
||||||
|
* the 'C' calling convention (from PNGCAPI) for
|
||||||
|
* callbacks (PNGCBAPI). This is no longer required
|
||||||
|
* in any known environment - if it has to be used
|
||||||
|
* please post an explanation of the problem to the
|
||||||
|
* libpng mailing list.
|
||||||
|
*
|
||||||
|
* These cases only differ if the operating system does not use the C
|
||||||
|
* calling convention, at present this just means the above cases
|
||||||
|
* (x86 DOS/Windows sytems) and, even then, this does not apply to
|
||||||
|
* Cygwin running on those systems.
|
||||||
|
*
|
||||||
|
* Note that the value must be defined in pnglibconf.h so that what
|
||||||
|
* the application uses to call the library matches the conventions
|
||||||
|
* set when building the library.
|
||||||
|

|
||||||
|
|
||||||
|
/* Symbol export
|
||||||
|
* =============
|
||||||
|
* When building a shared library it is almost always necessary to tell
|
||||||
|
* the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
|
||||||
|
* is used to mark the symbols. On some systems these symbols can be
|
||||||
|
* extracted at link time and need no special processing by the compiler,
|
||||||
|
* on other systems the symbols are flagged by the compiler and just
|
||||||
|
* the declaration requires a special tag applied (unfortunately) in a
|
||||||
|
* compiler dependent way. Some systems can do either.
|
||||||
|
*
|
||||||
|
* A small number of older systems also require a symbol from a DLL to
|
||||||
|
* be flagged to the program that calls it. This is a problem because
|
||||||
|
* we do not know in the header file included by application code that
|
||||||
|
* the symbol will come from a shared library, as opposed to a statically
|
||||||
|
* linked one. For this reason the application must tell us by setting
|
||||||
|
* the magic flag PNG_USE_DLL to turn on the special processing before
|
||||||
|
* it includes png.h.
|
||||||
|
*
|
||||||
|
* Four additional macros are used to make this happen:
|
||||||
|
*
|
||||||
|
* PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
|
||||||
|
* the build or imported if PNG_USE_DLL is set - compiler
|
||||||
|
* and system specific.
|
||||||
|
*
|
||||||
|
* PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
|
||||||
|
* 'type', compiler specific.
|
||||||
|
*
|
||||||
|
* PNG_DLL_EXPORT Set to the magic to use during a libpng build to
|
||||||
|
* make a symbol exported from the DLL. Not used in the
|
||||||
|
* public header files; see pngpriv.h for how it is used
|
||||||
|
* in the libpng build.
|
||||||
|
*
|
||||||
|
* PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
|
||||||
|
* from a DLL - used to define PNG_IMPEXP when
|
||||||
|
* PNG_USE_DLL is set.
|
||||||
|

|
||||||
|
|
||||||
|
/* System specific discovery.
|
||||||
|
* ==========================
|
||||||
|
* This code is used at build time to find PNG_IMPEXP, the API settings
|
||||||
|
* and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
|
||||||
|
* import processing is possible. On Windows systems it also sets
|
||||||
|
* compiler-specific macros to the values required to change the calling
|

|
* conventions of the various functions.
