In one of the labs here at ISU, we have a Xerox Kurzweil scanner connected to a PC clone, and we've been having problems with the files that the scanning software saves, especially when the scanner is used to scan graphics images and save in TIFF format. We would like to implement a kind of graphics previewer with the scanning software, using batch files. I manages to find several programs that allow TIFF files to be viewed on a PC. The problem is that all of these programs don't seem to like the TIFF files that are created by the scanning software of this scanner. I thoroughly checked these TIFF viewers out by generating TIFF images on other systems and viewing them, so the problem seems to lie with the scanning software in particular. I was just wondering if anyone else has had experience with this particular scanner, and has any suggestions. The scanning software seems to be creating faulty TIFF files, and I would be interested in findout out if a fix is available. BTW, as far as I know, the software we have for this scanner is the most up-to-date available. ------------------------------------------------------------- / Marc Barrett -MB- | BITNET: XGR39@ISUVAX.BITNET / / ISU COM S Student | Internet: XGR39@CCVAX.IASTATE.EDU / ------------------------------------------------------------ \ The great thing about standards is that / \ there are so many of them to choose from. / -------------------------------------------------------

BTW, as far as I know, the software ) we have for this scanner is the most up-to-date available. ) We have a Kurweil 5200 as well. The TIFF files that it creates are 400 dpi and CCITT Group 3 compression by default. The DTIFF program that I have for the PC will not decompress CCITT G3 (FAX or MODIFIED) nor CCITT G4 images. Your best bet is to set the image resolution to 300 dpi (or lower) and no compression and then try it again. BTW xv for X11R4 terminals will display the images. Also, I believe that some of the tags that Kurzweil uses in the TIFF files are no longer recommended in the TIFF standard. However, a robust TIFF reader should be able to cope with them anyway. Do you have a routine to dump TIFF header information?? Send me the details of the program you're using on the PC, and a text file with the ASCII dump of the TIFF tags and I might be able to help you more. What does the display software say (i.e. error messages)?? Or does it just display garabage? -- +---------------------------+-----------------------------------------------+ | Kevin O.

Dumb typo on my part! -- +---------------------------+-----------------------------------------------+ | Kevin O.
