2000.11.30 06:27 "Problem with CCITT Group 4 file", by Stefan Schulz
Hello, I try to read/view a tiff file with different Viewers for HP-UX. All these Viewers depent on libtiff. I got the newest version available for HP-UX 10.20, which is 3.5.4, but i still can't load these images. Here are the outputs from tiffinfo, tiffdump and the errormessage from xtiff: b077:/opt/tiff-3.5/bin$ ./tiffinfo /caddaten/BS/cadtransfer/cad/test2.tif TIFF Directory at offset 0x8 Image Width: 4976 Image Length: 7028 Resolution: 300, 300 Bits/Sample: 1 Compression Scheme: CCITT Group 4 Photometric Interpretation: min-is-white Rows/Strip: 7028 Planar Configuration: single image plane b077:/opt/tiff-3.5/bin$ ./tiffdump /caddaten/BS/cadtransfer/cad/test2.tif /caddaten/BS/cadtransfer/cad/test2.tif: Magic: 0x4949 <little-endian> Version: 0x2a Directory 0: offset 8 (0x8) next 0 (0) OldSubFileType (255) SHORT (3) 1<1> ImageWidth (256) LONG (4) 1<4976> ImageLength (257) LONG (4) 1<7028> BitsPerSample (258) SHORT (3) 1<1> Compression (259) SHORT (3) 1<4> Photometric (262) SHORT (3) 1<0> StripOffsets (273) LONG (4) 1<154> RowsPerStrip (278) LONG (4) 1<7028> StripByteCounts (279) LONG (4) 1<72096> XResolution (282) RATIONAL (5) 1<300> YResolution (283) RATIONAL (5) 1<300> b077:/opt/tiff-3.5/bin$ ./X11/xtiff /caddaten/BS/cadtransfer/cad/test2.tif /caddaten/BS/cadtransfer/cad/test2.tif: Using 1-bit PseudoColor visual. TIFFFillStrip: /caddaten/BS/cadtransfer/cad/test2.tif: Read error at scanline 4294967295; got 72088 bytes, expected 72096. Unfortunately i have no influence in generating these images, so i have to take what i get. Is there a way to read/view these files with libtiff? As viewers i tried gview, ImageMagick, xtiff and gimp which all depend on libtiff and all failed to open these files. Im no programmer, so if there is a solution to this problem and i have to edit/compile the sources, i need detailed instructions. Any help would be greatly appreciated. (Hope my english was good enough to describe my problem) Regards Stefan -- Mit freundlichen Gruessen / with kind regards Stefan Schulz / Systemadminstrator Bausch + Stroebel GmbH Internet: http://www.bausch-stroebel.com
