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 -********* - -Use `FT_Get_BDF_Charset_ID' to access the encoding and registry. - -The driver always exports `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 :-( - - -License -******* - -Copyright (C) 2000 by Francesco Zappa Nardelli - -Permission is hereby granted, free of charge, to any person obtaining -a copy of this software and associated documentation files (the -"Software"), to deal in the Software without restriction, including -without limitation the rights to use, copy, modify, merge, publish, -distribute, sublicense, and/or sell copies of the Software, and to -permit persons to whom the Software is furnished to do so, subject to -the following conditions: - -The above copyright notice and this permission notice shall be -included in all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, -EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF -MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. -IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY -CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, -TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE -SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. - - -Credits -******* - -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.
