Re: Importing graphics - need tips

["Sharron Fox" <sharron.fox@xxxxxxxx>]

Thanks for all the info, Thomas and a nice explanation of the DPI usage in
Frame. I produce documentation for a DOS product that has yet to migrate to
Windows so I don't use many GIFs and the ones we do use I thought might be
suspect. I did add a caveat to my reply message that I thought the creation
process could be the culprit..."However, our issue could be related to the
manner of creation".

Best regards,
Sharron Fox

The original image format used in the FM file has nothing to do with the
result in PDF. The distilling process knows *nothing* about the original
format. If your GIF images appear bad, they are either created badly in
the first place, or you use graphics not suited for the GIF format.
Since GIF only supports 256 colors, that could be one reason.
