I have been trying to use the program "HalfTone" to produce halftone images on the laserwriter from ThunderScan files, but I can't get it to recognize the files generated by the thunderscan software, even if I save it with the halftone information rather then as a MacPaint image. Has anyone else tried to use this program? Peter Wisnovsky Virtual Address: UUCP: ...ihnp4!psuvax1!6111231@pucc.bitnet

"GrayMap" files are created by holding down the Option key while re-halftoning a selected area. Details of this process are found on page 4-30 of the 'new' manual. Unfortunately, there is a bug in the ThunderScan software which distorts the image in these files. Documents scanned at 100% look OK, but other magnifications get stretched. I hope this helps.
