The specification of the BDF font format is +available from Adobe's web site: + + http://partners.adobe.com/asn/developer/PDFS/TN/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). + + +License +******* + +Copyright (C) 2001-2002 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. + +*** Portions of the driver (that is, bdflib.c and bdf.h): + +Copyright 2000 Computing Research Labs, New Mexico State University +Copyright 2001-2002 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.

There is no way of sending zero distance codes--a dummy must be + sent if there are none. (History: a pre 2.0 version of PKZIP would + store blocks with no distance codes, but this was discovered to be + too harsh a criterion.) Valid only for 1.93a. 2.04c does allow + zero distance codes, which is sent as one code of zero bits in + length. + 6. There are up to 286 literal/length codes. Code 256 represents the + end-of-block. Note however that the static length tree defines + 288 codes just to fill out the Huffman codes. Codes 286 and 287 + cannot be used though, since there is no length base or extra bits + defined for them. Similarily, there are up to 30 distance codes. + However, static trees define 32 codes (all 5 bits) to fill out the + Huffman codes, but the last two had better not show up in the data. + 7. Unzip can check dynamic Huffman blocks for complete code sets. + The exception is that a single code would not be complete (see #4). + 8. The five bits following the block type is really the number of + literal codes sent minus 257. + 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits + (1+6+6). Therefore, to output three times the length, you output + three codes (1+1+1), whereas to output four times the same length, + you only need two codes (1+3). Hmm. + 10. In the tree reconstruction algorithm, Code = Code + Increment + only if BitLength(i) is not zero. (Pretty obvious.) + 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) + 12.

If inflate returns Z_OK and with zero avail_out, it + must be called again after making room in the output buffer because there + might be more output pending. + + If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much + output as possible to the output buffer. The flushing behavior of inflate is + not specified for values of the flush parameter other than Z_SYNC_FLUSH + and Z_FINISH, but the current implementation actually flushes as much output + as possible anyway. + + inflate() should normally be called until it returns Z_STREAM_END or an + error. However if all decompression is to be performed in a single step + (a single call of inflate), the parameter flush should be set to + Z_FINISH. In this case all pending input is processed and all pending + output is flushed; avail_out must be large enough to hold all the + uncompressed data. (The size of the uncompressed data may have been saved + by the compressor for this purpose.) The next operation on this stream must + be inflateEnd to deallocate the decompression state. The use of Z_FINISH + is never required, but can be used to inform inflate that a faster routine + may be used for the single inflate() call. + + If a preset dictionary is needed at this point (see inflateSetDictionary + below), inflate sets strm-adler to the adler32 checksum of the + dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise + it sets strm->adler to the adler32 checksum of all output produced + so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or + an error code as described below. At the end of the stream, inflate() + checks that its computed adler32 checksum is equal to that saved by the + compressor and returns Z_STREAM_END only if the checksum is correct. + + inflate() returns Z_OK if some progress has been made (more input processed + or more output produced), Z_STREAM_END if the end of the compressed data has + been reached and all uncompressed output has been produced, Z_NEED_DICT if a + preset dictionary is needed at this point, Z_DATA_ERROR if the input data was + corrupted (input stream not conforming to the zlib format or incorrect + adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent + (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not + enough memory, Z_BUF_ERROR if no progress is possible or if there was not + enough room in the output buffer when Z_FINISH is used.

The default value is 8. See zconf.h for total memory + usage as a function of windowBits and memLevel. + + The strategy parameter is used to tune the compression algorithm.

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. + +Informations 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 informations 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.
