Scanner Utility

Description

The other program, xnscan, is an X windows version of the nscan program. It allows previewing to make adjusting the parameters easier. Both programs may not be on all machines right now but should be available in the near future.

Both programs store the image data in pnm formats (i.e. pbm, pgm, ppm). They are just for getting the raw image data from the scanner and into a file. Further manipulations and compression of these files can be accomplished using other programs such as XV, photoshop, netpbm utilities, etc.
