I suggest you switch to a 'terminal' font designed to be drawn as a
bitmap. Helvetica is NOT such a font.
Also use the 'threhold' control I explained in my previous email and in
IM Examples, formats, GIF to remove any 'IM version threshold' problem
you may have.
Basically you have a difficult problem, which I cant help you with.
For testing I suggest you use the simpler command...
convert -font "NimbusRomanNo9" -pointsize 12 -background none \
label:File t.gif
display -remote t.gif &
The -remote means display in an existing display window if one exists,
otherwise start one.
You can also try the +antialias setting though I have not had much
success with it for font drawing.
If you find a good font, or any other interesting point, PLEASE let me
know. I am sure a lot of people would like a BITMAP drawn font for use
in GIF images, especially with transparent backgrounds.
