You are entitled to do with +the files of which it consists whatever you wish. If you alter a file, +however, please remove the line containing the comment + + `This file belongs to the MFTOEPS package.' + +in order to avoid a mess. + +The kernel of this little package is the METAFONT program MFTOEPS.MF written +by Bogus\l{}aw Jackowski, Piotr Pianowski and Marek Ry\'cko. The aim of the +program is to produce EPS (encapsulated PostScript) files readable by +CorelDRAW!(R), Adobe Illustrator(TM) and Fontographer(R). + +The user of the package is supposed to be familiar a bit with METAFONT and +PostScript. Donald E. Knuth's ``The METAFONTbook'' and Adobe's ``PostScript +Language Reference Manual'' (both by Addison-Wesley Publishing Company, Inc.) +should be consulted in the case of doubts. + +There is a bunch of simple examples in the subdirectory M2ESAMP. The +directory ../PROGS contains DOS batch files and other programs which, +possibly after some adjustments, can be used to generate EPS files. + +Roughly, the machinery works as follows: the resulting PostScript code +is written by METAFONT to a LOG file; the LOG file is then processed +either by AWK or by TeX (see the PROGS subdirectory) in order to extract +the PostScript code. The idea seems straightforward; however, even +a partial conciliation of the worlds of CorelDRAW! and Adobe Illustrator +was not so much straightforward. + +----------------------------------------------------------------------------- + +In addition to the main MFTOEPS package, there are two ``bonus'' packages in +directories ../EPSTOMF and ../ROEX. EPSTOMF converts ``canonical'' EPS files, +i.e., files conforming the structure of the files generated by the MFTOEPS +package, into the METAFONT lingo; ROEX is a set of METAFONT macros +accomplishing the task of removing overlaps and expanding strokes (for +details see there). + +----------------------------------------------------------------------------- + +INTERFACE SYNOPSIS + +Conventions: In the following we shall use words `number,' `pair,' `string,' +and `path' as an abbreviation for `numeric expression,' `pair expression,' +`string expression,' and `path expression,' respectively. The signs `less' +and `greater,' used for marking parameters of macros, are +``meta-characters,'' i.e., they do not belong to the METAFONT code. + +There are fifteen interface macros defined in the MFTOEPS.MF file: + eps_mode_setup + write_preamble + write_postamble + set_BB + find_BB + reset_BB + fill_C + draw_C + clip_C + fix_line_width + fix_line_join + fix_line_cap + fix_line_miter_limit + fix_fill_cmyk + fix_draw_cmyk + +COMMAND eps_mode_setup +USAGE eps_mode_setup <an optional number (0 or 1)>; +REMARKS This command should be used instead of the usual |mode_setup| + command. The forms |EPS_mode_setup| and |EPS_mode_setup 1| + are equivalent. One of them (preferably the former one) should + be used for normal processing. Invoking |EPS_mode_setup 0| + is meant primariliy for testing purposes and is supposed + to be used by experienced programmers who know what they are doing. + There are two predefined constants in MFTOEPS.MF to be used in this + context, namely, |no_export_level=0| and |compatibility_level=1|. + It is advisable to use the names of the constants rather than + bare numbers. + +COMMAND write_preamble +USAGE write_preamble <string>; +REMARKS This command initialises the process of writing of the PostScript + code. The string expression is the name (without extension) + of the resulting EPS file; the extension is always |.EPS|. + METAFONT is switched to the |batchmode| in order to avoid + slowing down the process by writing mess(ages) to the terminal. + The inspection of the log file is thus highly recommended. + +COMMAND write_postamble +USAGE write_postamble; +REMARKS This command ends writing of the PostScript code, switches METAFONT + back to the |errorstopmode|, and performs neccessary ``last minute'' + actions (see below). + +COMMANDS set_BB find_BB reset_BB +USAGE set_BB <four numbers or two pairs separated by commas>; + find_BB <a list of paths separated by commas>; + reset_BB; +REMARKS Commands |set_BB| or |find_BB| should be invoked prior to + invoking |write_preamble|. |set_BB| sets the coordinates of + the corners of the bounding box of a graphic object; it is + useful when the bounding box of a graphic object is + known in advance or if it is required to force an artificial + bounding box. |find_BB| computes the respective bounding box + for a list of paths; if several |find_BB| statements are + used, the common bounding box is calculated for all paths + that appeared in the arguments. The result is stored in the + variables |xl_crd|, |yl_crd|, |xh_crd|, and |yh_crd|. There + are two functions, |llxy| and |urxy|, returning pairs + |(xl_crd,yl_crd)| and |(xh_crd,yh_crd)|, respectively. The + last command, |reset_BB|, makes |xl_crd|, |yl_crd|, + |xh_crd|, and |yh_crd| undefined (the initial situation); + |reset_BB| is performed by the |write_postamble| macro, + which is convenient in the case of generating several + several EPS files in a single METAFONT run. + +COMMANDS fill_C draw_C +USAGE fill_C <a list of paths separated by commas>; + draw_C <a list of paths separated by commas>; +REMARKS These commands are to be used instead of the usual + METAFONT |fill| and |draw| ones. They cause that a list of paths + followed by the PostScript operation |eofill| (|fill_C|) or |stroke| + (|draw_C|) is translated to a PostScript code. The list of paths + constitutes a single curve in the sense of PostScript. + +COMMAND clip_C +USAGE clip_C <a list of paths separated by commas, possibly empty>; +REMARKS The macro |clip_C| with a non-empty parameter works similarly to + the |fill_C| command, except that the |eoclip| operator is issued + instead of |eofill|. This causes an appropriate change of + the current clipping area. According to PostScript's principles, + the resulting area is a set product of the current clipping + area and the area specified in the argument of the |eoclip| + command. The empty parameter marks the end of the scope + of the most recent |clip_C| command with a non-empty parameter. + In other words, nested |clip_C| commands form a ``stack'' structure. + If needed, the appropriate number of parameterless |clip_C| + commands is issued by the |write_postamble| macro, thus + the user needs not to care about it. + WARNING: files produced with the use of |clip_C| are + interpreted properly by Adobe Illustrator (provided paths + directions are defined properly) but not by CorelDRAW! (ver. 3.0). + +COMMANDS fix_line_width fix_line_join fix_line_cap fix_miter_limit fix_dash +USAGE fix_line_width <a non-negative number (dimension)>; + fix_line_join <a number (0, 1 or 2)>; + fix_line_cap <a number (0, 1 or 2)>; + fix_miter_limit <a number greater or equal 1>; + fix_dash (<a list of numbers (dimensions), possibly empty>) + <number (dimension)>; +REMARKS These command are to be used in connection with the |draw_C| + command. |fix_line_width| fixes the thickness of the outline. + The other three commands correspond to PostScript operations + |setlinejoin|, |setlinecap|, |setmiterlimit|, and |setdash| (see + ``PostScript Language Reference Journal'' for details). + + All commands should be used after |write_preamble|, as + |write_preamble| sets the default thickness (0.4pt), default + line join (0), default line cap (0), default miter limit (10), + and a solid line as a default for stroking (|fix_dash () 0|). + +COMMANDS fix_fill_cmyk fix_draw_cmyk +USAGE fix_fill_cmyk <four numbers separated by commas>; + fix_draw_cmyk <four numbers separated by commas>; +REMARKS These commands define the colours of the interiors of graphic + objects (|fix_fill_cmyk|) and colours of outlines (|fix_draw_cmyk|) + using cyan-magenta-yellow-black model (basic model). They should + be used after |write_preamble| (because |write_preamble| defines + the black colour as a default for both macros) and prior to invoking + the corresponding |fill_C| and |draw_C| commands, respectively. + There are also (just in case) macros |fix_fill_rgb| and + |fix_draw_rgb| using red-green-blue model; the argument to both + macros is a triple of numbers. (The user can control the process + of conversion from RGB to CMYK by the redefinition of macros + |under_color_removal| and |black_generation|.) The numbers + forming the arguments of the macros are supposed to belong to + the interval [0..1]. + +ADDITIONAL FUNCTIONS pos_turn neg_turn +USAGE pos_turn <primary path expression> + neg_turn <primary path expression> +REMARKS Each function returns the path passed as the argument, + except that the orientation of the path is changed, if + necessary: |pos_turn| returns paths oriented anti-clockwise, + |neg_turn|---oriented clockwise. This may be + usefull for creation pictures which are to be processed + further by Adobe Illustrator, because this program is + sensitive to the orientation of paths. + +CONTROL VARIABLES yeseps yesEPS YESEPS +REMARKS No EPS file will be generated unless one variable among + |yeseps| or |yesEPS| or |YESEPS| is assigned a definite value. + It is advisable to set this variable in a command line + (see M2E.BAT and M2E-ALT.BAT in the PROGS directory). + In fact, using |yeseps| is reccomended. Aliases |yesEPS| + and |YESEPS| were introduced for ``historical'' reasons. + +CONTROL VARIABLE testing +REMARKS If the variable |testing| is assigned a definite value, the whole + PostScript code is flushed to the terminal, thus slowing + down significantly the process of generation of an EPS file + (cf. the description of the |write_preamble| command). + +----------------------------------------------------------------------------- + +ENCOURAGEMENT + +The inspection of the source code of the MFTOEPS.MF program may reveal +a few more useful macros. + +----------------------------------------------------------------------------- + +END OF THE 0MFTOEPS.DOC FILE diff --git a/Master/texmf-dist/source/metafont/mftoeps/m2esamp/0m2esamp.doc b/Master/texmf-dist/source/metafont/mftoeps/m2esamp/0m2esamp.doc new file mode 100644 index 00000000000..fd27e761c4a --- /dev/null +++ b/Master/texmf-dist/source/metafont/mftoeps/m2esamp/0m2esamp.doc @@ -0,0 +1,35 @@ +This file belongs to the MFTOEPS package. + +The directory M2ESAMP contains the following files: + 0M2ESAMP.DOC this file + CLIPCIR.MF a bogus application of clipping: a variation of CLIPSQR.MF + CLIPSQR.MF a bogus application of clipping: Sierpi\'nski's carpet + HOLECLIP.MF a nearly trivial example + HOLECLIP.TEX an example of using HOLECLIP.EPS + HOLEFILL.MF a nearly trivial example + POLYGONS.MF input for SAMPLE*.MF files + RECTAN.MF a truly trivial example + RECTAN_.BAT DOS batch file for RECTAN.MF (generates RECTAN.EPS) + SAMPLE1A.MF less trivial example + SAMPLE1B.MF modification of SAMPLE1A.MF + SAMPLE2A.MF regular polygon with circumscribed ``flex'' polygon + SAMPLE2B.MF ditto---a variation + SAMPLE2C.MF ditto---a variation + SAMPLE2D.MF ditto---a variation + SAMPLE2E.MF ditto---a variation + SAMPLE3.MF four pictures (``flowers'') + SAMPLE4.MF four pictures (``galaxies'') + SAMPLE5.MF four pictures (``shells'') + STEREO.MF two pictures that can be used for + constructing a simple stereogram + +You are entitled to do with these files whatever you wish.
