Sprawdziłem fonty z tp7 borlanda (http://mono.i-demo.pl/tp7bgi.zip ).
W programiku java (http://mono.i-demo.pl/chrdraw2.jar ) uwzględniłem parametr "origin to bottom" i jego znak (jest jeszcze "origin to baseline", ale we wszystkich dotychczasowych fontach jest ustawiony na 0 - obecnie nie uwzględniam go, bo nie wiem nawet czy ma znak czy nie). W programiku atari (http://mono.i-demo.pl/chrdraw2.atr ) dałem 20k bufor na font.
Poniżej zrzuty ekranu z pc i atari.
