- FreeType font driver for BDF fonts
-
- Francesco Zappa Nardelli

-
-Introduction
-************
-
-BDF (Bitmap Distribution Format) is a bitmap font format defined by Adobe,
-which is intended to be easily understood by both humans and computers.
-This code implements a BDF driver for the FreeType library, following the
-Adobe Specification V 2.2. The specification of the BDF font format is
-available from Adobe's web site:
-
- https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5005.BDF_Spec.pdf
-
-Many good bitmap fonts in bdf format come with XFree86 (www.XFree86.org).
-They do not define vertical metrics, because the X Consortium BDF
-specification has removed them.
-
-
-Encodings
-*********
-
-The variety of encodings that accompanies bdf fonts appears to encompass the
-small set defined in freetype.h. On the other hand, two properties that
-specify encoding and registry are usually defined in bdf fonts.
-
-I decided to make these two properties directly accessible, leaving to the
-client application the work of interpreting them. For instance:
-
-
- #include FT_INTERNAL_BDF_TYPES_H
-
- FT_Face face;
- BDF_Public_Face bdfface;
-
-
- FT_New_Face( library, ..., &face );
-
- bdfface = (BDF_Public_Face)face;
-
- if ( ( bdfface->charset_registry == "ISO10646" ) &&
- ( bdfface->charset_encoding == "1" ) )
- [..]
-
-
-Thus the driver always exports `ft_encoding_none' as face->charmap.encoding.
-FT_Get_Char_Index's behavior is unmodified, that is, it converts the ULong
-value given as argument into the corresponding glyph number.
-
-If the two properties are not available, Adobe Standard Encoding should be
-assumed.
-
-
-Anti-Aliased Bitmaps
-********************
-
-The driver supports an extension to the BDF format as used in Mark Leisher's
-xmbdfed bitmap font editor. Microsoft's SBIT tool expects bitmap fonts in
-that format for adding anti-aliased them to TrueType fonts. It introduces a
-fourth field to the `SIZE' keyword which gives the bpp value (bits per
-pixel) of the glyph data in the font. Possible values are 1 (the default),
-2 (four gray levels), 4 (16 gray levels), and 8 (256 gray levels). The
-driver returns either a bitmap with 1 bit per pixel or a pixmap with 8bits
-per pixel (using 4, 16, and 256 gray levels, respectively).
-
-
-Known problems
-**************
-
-- A font is entirely loaded into memory. Obviously, this is not the Right
- Thing(TM). If you have big fonts I suggest you convert them into PCF
- format (using the bdftopcf utility): the PCF font drive of FreeType can
- perform incremental glyph loading.
-
-When I have some time, I will implement on-demand glyph parsing.
-
-- Except for encodings properties, client applications have no visibility of
- the PCF_Face object. This means that applications cannot directly access
- font tables and must trust FreeType.
-
-- Currently, glyph names are ignored.
-
- I plan to give full visibility of the BDF_Face object in an upcoming
- revision of the driver, thus implementing also glyph names.
-
-- As I have never seen a BDF font that defines vertical metrics, vertical
- metrics are (parsed and) discarded. If you own a BDF font that defines
- vertical metrics, please let me know (I will implement them in 5-10
- minutes).
