+ FreeType font driver for PCF fonts
+
+ Francesco Zappa Nardelli
+ <francesco.zappa.nardelli@ens.fr>
+
+
+Introduction
+************
+
+PCF (Portable Compiled Format) is a binary bitmap font format, largely used
+in X world. This code implements a PCF driver for the FreeType library.
+Glyph images are loaded into memory only on demand, thus leading to a small
+memory footprint.
+
+Information on the PCF font format can only be worked out from
+`pcfread.c', and `pcfwrite.c', to be found, for instance, in the XFree86
+(www.xfree86.org) source tree (xc/lib/font/bitmap/).
+
+Many good bitmap fonts in bdf format come with XFree86: they can be
+compiled into the pcf format using the `bdftopcf' utility.
+
+
+Supported hardware
+******************
+
+The driver has been tested on linux/x86 and sunos5.5/sparc. In both
+cases the compiler was gcc. When back in Paris, I will test it also
+on linux/alpha.
+
+
+Encodings
+*********
+
+The variety of encodings that accompanies pcf fonts appears to encompass the
+small set defined in freetype.h. On the other hand, each pcf font defines
+two properties that specify encoding and registry.
+
+I decided to make these two properties directly accessible, leaving to the
+client application the work of interpreting them. For instance:
+
+ #include "pcftypes.h" /* include/freetype/internal/pcftypes.h */
+
+ FT_Face face;
+ PCF_Public_Face pcfface;
+
+ FT_New_Face( library,..., &face );
+
+ pcfface = (PCF_Public_Face)face;
+
+ if ((pcfface->charset_registry == "ISO10646") &&
+ (pcfface->charset_encoding) == "1")) [..]
+
+Thus the driver always export `ft_encoding_none' as
+face->charmap.encoding. FT_Get_Char_Index() behavior is unmodified, that
+is, it converts the ULong value given as argument into the corresponding
+glyph number.
+
+
+Known problems
+**************
+
+- dealing explicitly with encodings breaks the uniformity of freetype2
+ api.
+
+- except for encodings properties, client applications have no
+ visibility of the PCF_Face object. This means that applications
+ cannot directly access font tables and are obliged to trust
+ FreeType.
+
+- currently, glyph names and ink_metrics are ignored.
+
+I plan to give full visibility of the PCF_Face object in the next
+release of the driver, thus implementing also glyph names and
+ink_metrics.
+
+- height is defined as (ascent - descent). Is this correct?
+
+- if unable to read size information from the font, PCF_Init_Face
+ sets available_size->width and available_size->height to 12.
+
+- too many english grammar errors in the readme file :-(

+Keith Packard wrote the pcf driver found in XFree86. His work is at
+the same time the specification and the sample implementation of the
+PCF format. Undoubtedly, this driver is inspired from his work.
