* @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, bzip2 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 bzip2 compressed stream
|
||||
* from it and re-open the face with it.
|

|
||||
* LCD Filtering
|
||||
*
|
||||
* @abstract:
|
||||
* Reduce color fringes of subpixel-rendered bitmaps.
|
||||
*
|
||||
* @description:
|
||||
* Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your
|
||||
* `ftoption.h', which enables patented ClearType-style rendering,
|
||||
* the LCD-optimized glyph bitmaps should be filtered to reduce color
|
||||
* fringes inherent to this technology. The default FreeType LCD
|
||||
* rendering uses different technology, and API described below,
|
||||
* although available, does nothing.
|
||||
*
|
||||
* 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. 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.
|
||||
*
|
||||
* 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)

* When querying for information about the character set of the font

|

* 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://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.

/* very slow to compute (even if the size of global */

/* hints is really small). */

/* */
|

/* - glyph hints: These describe some important features of the glyph */

/* outline, as well as how to align them. They are */

/* generally much faster to compute than global hints. */
|
||||
/* */
|

/* The current FreeType auto-hinter does a pretty good job while */

/* performing fast computations for both global and glyph hints. */
|

/* However, we might be interested in introducing more complex and */

/* powerful algorithms in the future, like the one described in the John */

* FT_Get_PS_Font_Value
|

*
|
||||
* @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.
|
||||
*
|
||||
* @since:
|
||||
* 2.4.8
