I'm not sure if I understand. But if you choose a font that is
NOT found it displays an error message followed by all available fonts.
If it finds the font it displays nothing. In this case I probably
gave to much information in the error message by suggesting all
the legal values :-).

The easiest way to choose a font is to use the menu to select
it (test it with LABEL). Then use SHOW LABELFONT to see the correct
parameters syntax of the font. Then use that in your program.
Use the clipboard or assign it to variable to save typing and
mistakes.

GIF images have lots of color limitations. Because of this the
GIF generation code has to make trade-offs. I use a 3rd party package
to do the color conversion. You may find one package does better
with one image and poor with another image. And you may find the reverse
is true with another package. Some real high end packages might
examine how you used color and make the best choice for either
picture.

What color mode are you working in?

When your doing GIF's working in 256 color will probably give you
the most similar GIF result but still will not be exact.

Remember when working in 256 color and using lots of colors you
have to CLEARPALETTE now and then see Status Window.

Other compressed graphics image files make different tradeoffs.
