The PicData: line specifies how big the image is; the Image: (not
ImageData:) line, how big it is supposed to be. In other words, the
pixels in the image are not necessarily square. If you're not handling
the Image: line, then most of your images will be TOO FAT.
So far I have seen four face-to-whatever programs posted. The two that
convert to PostScript handle Image: by letting PostScript do the
rescaling. The two that convert to something else do not handle
Image:. My own (unreleased) program is the only one I know of that
both converts to another raster format and handles Image:.
