/* * NAME * ps2pk - creates a PK font from a type1 PostScript font * SYNOPSIS: * pk2pk [options] type1 [pkname] * DESCRIPTION * This program renders a given type1 PostScript font at a given * pointsize (default 10.0 points) and resolution (default 300dpi) * into a TeX PK font. * * To generate the PK font pk2ps needs a valid type1 fontname (for * example Utopia-Regular.pfa) and its corresponding AFMfile * (Utopia-Regular.afm). The program accepts both the MSDOS binary * type1 format (Utopia-Regula.pfb) and its UNIX ASCII equivalent * (Utopia-Regula.pfa). The resulting PK font does contain all * characters for which the C-code is non negative. This can be * overruled by specifying an explicit via the -e * option. Character codes in AMF files are specified as integer values * after the C, for example Utopia-Regular.afm provides: * C 251 ; WX 601 ; N germandbls ; B 22 -12 573 742 ; * C -1 ; WX 380 ; N onesuperior ; B 81 272 307 680 ; * * The `germandbls' has code 251 and `onesuperior' -1 which means * that this character is not part of the default AdobeStandard- * Encoding scheme. To get this `onesuperior' you have to add it to * an encoding vector as described in the PostScript manuals. But of * course it is better to use standard encodings, like the one provided * with the new psfonts. This `TeXBase1Encoding' encoding does contain * all names of characters as defined in the 256 character TeX fonts. * * The location of files for ps2pk, since version 1.5, has been * improved using PostScript resource databases. These databases * can be created using Adobe's mkpsres(1) utility. On UNIX the * default name is PSres.upr and can be found in directories like * /usr/lib/DPS depending on the machine you are using. The * following example of an UPR file contains three resources * PS-Resources-1.0 * Encoding * FontAFM * FontOutline * . * //usr/local/tex/fonts/type1faces * Encoding * ECEncoding=EC.enc * . * FontAFM * Courier=ResidentFonts/Courier.pfa * . * FontOutline * Courier=ResidentFonts/Courier.afm * . * * When this UPR is in the PSRESOURCEPATH ps2pk can make an EC encoded * PK font for Courier with: * * ps2pk -eECEncoding Courier * * It is also possible without the UPR file but then you have to * set T1INPUTS to the directories containing the files you need, * for example: * * setenv T1INPUTS /usr/local/tex/fonts/type1faces// * * and to run ps2pk by providing the proper filenames: * * ps2pk -eEC.enc Courier.pfa * * In both cases the result will be the PK font Courier10.300pk. * * PostScript resource databases eliminate the need for recursive * directory search, this is done by mkpsres(1) instead. And all * resources can be stored in one directory per computer keeping * maintenance easy. Another advantage is the mapping of internal * PostScript names, which are case sensitive and not restricted to * MSDOS limitations, to external platform dependant filenames in * a very natural way. On a MSDOS computer psres.dpr (the equivalent * of PSres.upr) could be: * PS-Resources-1.0 * Encoding * FontAFM * FontOutline * . * Encoding * TeXBase1Encoding=c:\emtex\dvips\8r.enc * . * FontAFM * Courier=c:\psfonts\com_____.pfb * . * FontOutline * Courier=c:\psfonts\afm\com_____.afm * . * * Given this psres.dpr resource database * * ps2pk -eTeXBase1Encoding Courier * * will create Courier10.300pk. Unfortunately MSDOS will abbreviate * this name to COURIER1.300. Mkpsres(1) is an improved version * of Adobe's makepsres(1) that runs on UNIX and MSDOS. This program * will treat PFB fonts and PFM fonts correctly and recognize * filenames ending with ".enc" as encoding vectors. * * If the name of does not contain an explicit extension * or directory separator it is considered as the name of a resource. * Otherwise as a filename. You can not mix up resource names and file- * names. Filenames must have an extension! * * OPTIONS AND ARGUMENTS * -a The name of the AFM resource or file can be * overruled with this option. * -e The encoding scheme (default the encoding from the * AFM file is used). * -E The extension factor (real value, default 1.0). * -O Create old checksums (for compatibility) * -P The desired pointsize (real value, default 10.0 * points). PK fonts created with a value different * to 10.0 will cause dvips warnings `dvips: Design * size mismatch in font ...'. * -R The base resolution (integer value, default 300 * dpi). Only used for creating METAFONT compatible * identification strings in PK postamble. * -S The slant (real value, default 0.0). * -X The resolution (integer value) in the X direction * (default 300 dpi). * -Y The resolution (integer value) in the Y direction * (defaults to the value of ). * -d Debug stat() calls during recursive path searching * -v Verbose flag. (Tells what the program is doing.) * * type1font The name of the PostScript type 1 font. When no * explicit AFMfile is given via the -a option the * name of the AFMfile will be constructed from this * name by removing the extension (if supplied) and * adding ".afm". * [pkname] The name of the resulting PK font can be overruled * with this name. The default name of the PK font is * derived from the basename of the type1 font, the * pointsize and . For example: * ps2pk -P17.28 Utopia-Regular * will result in: * Utopia-Regular17.300pk * * ENVIRONMENTS * * PSRESOURCEPATH * The path used for locating PS resource database files (PSres.upr * on UNIX and psres.dpr on MSDOS). The default of the path will be * shown by running ps2pk with the -v flag and a non-existant resource * name. * * T1INPUTS * The path used for locating PS type1 fonts, their AFM files and * encoding vectors. Path may contain '//' (UNIX) or '!!' (MSDOS) to * force ps2pk to look into subdirectories. Using PSRESOURCEPATH * instead of T1INPUTS avoids recursion. The default of the path will * be shown by running ps2pk with the -v flag and a non-existant * filename. * * ACKNOWLEDGEMENTS * This program uses the type1 hinting and rendering software IBM * has donated to the X-consortium. * * Since version 1.5 the lookup of PS resources as described in * `Programming the Display PostScript System with X (Appendix A: * Locating PostScript Resources)' from Adobe Systems is used. * SEE ALSO * ``METAFONT: The Program'', Donald Knuth. * ``The GFtoPK processor'', belonging to the METAFONTware. * afm2tfm(1) * mkpsres(1) * mtpk(1) * pk2bm(1) * pkfonts(1) * VERSIONS * 1.1 (May 1992) * 1.3 (August 1992) * 1.4 (December 1994) * 1.5 (Januari 1996) * AUTHOR * Piet Tutelaers * rcpt@urc.tue.nl */ #include #include #include #include /* PostScript Resource lookup functions */ /* #include "PSres.h" */ #include "basics.h" /* basic definitions and fatal() */ #include "filenames.h" /* newname(), extension(), ps_resource() */ #include "psearch.h" /* path search functions */ #include "pkout.h" /* PK output functions */ /* begin interface to type 1 software */ #include "ffilest.h" FontScalableRec vals;
