No, it isn't, and it's crap that OCR Servant doesn't do it already. Count me in as complaining about that too! > Again, these files are often produced somewhere else.

The OCR software needs to look at the image as pixels and compression (in general) doesn't change the number of pixels, only their representation. Removing the density and image depth limitations of OCR Servant would make it a much more useful service. That's uncontestable. It would require less knowledge on the part of the user, make the interface smoother, and might even increase functionality. Very NeXT things to do. These changes >are< possible. That's certain in my mind, because I have a hack front-end program that does these things. (PBMPLUS would do most of it.) The question then is: Is HSD going to fix it?
