metafont v cstexu

[Martin Osovsky]

Dobry den,

  jsem zacatecnik v metafontu, ale ucim se, presneji receno postupuji
presne podle METAFONTBooku Prof. Knutha. Jiste si proto dovedete predstavit
nemile prekvapeni, ktere me cekalo.
  Stalo se toto:

 V kapitole 5 vyse uvedene knihy je priklad, jenz je treba prepsat do souboru
a dale jej v kapitole pouzivat, jenze - uvedeny priklad opsan pismenko po
pismenku, mezera po mezere, carecka po carecce - ohlasi chybu hned na prvnim
radku! ( prave v metafontu v CSTeXu) Nejpreve jsem si tedy vsiml, ze nebyla
naloudovana zadna baze ( coz bych jako uplny zacatecnik, ktery postupuje pri
uceni presne podle metafontbooku vlastne vubec nemel vedet !) a zacal jsem
misto prosteho ** io.mf jinak : ** &plain io.mf. Ale ani to nepomohlo, a vic
jako zacatecnik opravdu nevim (snad jedine, ze by nebyl metafont spusten v
zadneme modu - ale myslim, ze mod proof se automaticky nastavi, nicht war?).

Pripojuji soubory io.mf a io.log:

***********************  io.mf ************************
mode_setup;
 em#:=10pt#; cap#:=7pt#;
 thin#:=1/3pt#; thick#:=5/6pt#;
 o#:=1/5pt#;
define_pixels(em,cap);
define_blacker_pixels(thin,thick);
define_corrected_pixels(o);
 curve_sidebar=round 1/18em;
beginchar("O",0.8em#,cap#,0); "Pismeno O";
 penpos1(thick,10);penpos2(.1[thin,thick],90-10);
 penpos3(thick,180+10);penpos4(thin,270-10);
 x1l=w-x3l=curve_sidebar;x2=x4=.5w;
 y1=.49h; y2l=-o; y3=.51h; y4l=h+o;
 penstroke z1e{down}..z2e{right}
            ..z3e{up}..z4e{left}..cycle;
 penlabels(1,2,3,4); endchar;
def test_I(expr code,trial_stem,trial_width) =
 stem#:=trial_stem*pt#; define_blacker_pixels(stem);
 beginchar(code,trial_width*em#,cap#,0); "Pismeno I";
  penpos1(stem,15); penpos2(stem,12); penpos3(stem,10);
  x1=x2=x3=.5w; y1=h; y2=.55h; y3=0; x2l:=1/6[x2l,x2];
  penstroke z1e..z2e{down}..z3e;
  penlabels(1,2,3); endchar; enddef;
