[comp.sys.atari.st] GDOS, OPUS and BSTAT

CHIASSA@UDEM.BITNET (Alyre CHIASSON) (08/08/89)

 Having tried to get OPUS and BSTAT to work with GDOS has left me
 with a few questions concerning GDOS font management. OPUS
 documentation pointed out that the ASSIGN file of TIMEWORKS
 DESKTOP PUBLISHER has screen fonts that are not listed in the
 printer fonts. I ckecked and yes this is true! Not only
 that but among all the screen and printer fonts listed only two
 matched up regarding font type and point size. What happens when
 the program tries to do a print with a screen font that has no
 matching printer font, or the case where there is a printer font
 but the wrong point size?

 Both OPUS and BSTAT look great though the latter replies better
 to my needs. I work in french so I often need access to the
 different accents which I do with a program that I run from
 the auto folder. OPUS acknowledges whatever the accent program does
 (keyboard interupt?) but BSTAT does not. What determines if a
 program does or doesn't respond to programs that give access to
 foreign characters? Can I do something to get BSTAT to accept
 french accents? The only thing I find lacking in the graph
 features of both programs is subscript and superscript for
 scientific labels. I am current designing some greek letters
 with FONTZ! but I would like to be able to place them in either
 superscript or subscript position.

It is possible (and apparently common) to use a GDOS font both at it's defined
point size and at multiples of it's point size. For instance, a 7-point font
can be used to print a 14 point font. The results are never as good, the
letters of the doubled font are noticeably jagged or blocky, since the
resolution of the doubled font is halved. The reason for doing it is the
substantial task of creating yet another font size is eliminated. Easydraw 
2.3 uses this trick for some fonts; I'm only guessing that this is what
Timeworks DTP is doing.
