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:.
