- Hi!
-
- I have some trouble with tiff-v3.3beta021. The library is being used on a SGI
- INDY running IRIX 5.2.
-
- My problem is related to the routine TIFFGetField and I have directed the
- problem to various NEWS groups as well - with no success. The files I have been
- testing at shows correct information using tiffdump. Furthermore, I have tested
- my program using both cc and gcc 2.6.3.
-
- Description of the problem:
- When I use TIFFGetField to read the different fields correct information is
- gained from: TIFFTAG_IMAGEWIDTH, TIFFTAG_IMAGELENGTH, TIFFTAG_BITSPERSAMPLE,
- TIFFTAG_COMPRESSION, TIFFTAG_IMAGEDESCRIPTION, TIFFTAG_PHOTOMETRIC,
- TIFFTAG_STRIPOFFSETS, TIFFTAG_SAMPLESPERPIXEL and TIFFTAG_PLANARCONFIG while
- incorrect information is gained from TIFFTAG_ROWSPERSTRIP and
- TIFFTAG_STRIPBYTECOUNTS. The incorrect information show no resemblance with the
- "real" information.
-
- Do You have any idea of what I am doing wrong?? I have run out of ideas.......
-
- Sincerely
- Oystein
-
- PS I have included part of the program:
-
- #include <stdio.h>
- #include <stdlib.h>
- #include <string.h>
-
- #include "/usr/local/tiff-v3.3beta021/libtiff/tiffio.h"
-
- main()
- {
- TIFF *in;
- uint32 imagewidth, imageheight, *offset;
- uint16 samplesperpixel;
- uint32 rowsperstrip;
- uint32 *stripbytecounts;
- uint16 bitspersample, compression, photomint, plcf;
- char filename[19]= {"../data/test.tif"};
-
- /* Open TIF file for reading of IFD and image data */
-
- in=TIFFOpen(filename, "r");
-
- /* Read TIF tag information that is needed in the fortran program */
-
- TIFFGetField(in, TIFFTAG_IMAGEWIDTH, &imagewidth);
- TIFFGetField(in, TIFFTAG_IMAGELENGTH, &imageheight);
- TIFFGetField(in, TIFFTAG_BITSPERSAMPLE, &bitspersample);
- TIFFGetField(in, TIFFTAG_COMPRESSION, &compression);
- TIFFGetField(in, TIFFTAG_IMAGEDESCRIPTION, &description);
- TIFFGetField(in, TIFFTAG_PHOTOMETRIC, &photomint);
- TIFFGetField(in, TIFFTAG_STRIPOFFSETS, &offset);
- TIFFGetField(in, TIFFTAG_SAMPLESPERPIXEL, &samplesperpixel);
- TIFFGetField(in, TIFFTAG_ROWSPERSTRIP, &rowsperstrip);
- TIFFGetField(in, TIFFTAG_STRIPBYTECOUNTS, &stripbytecounts);
- TIFFGetField(in, TIFFTAG_PLANARCONFIG, &plcf);
-
- printf("%s %u\n", " Image width= ", imagewidth);
- printf("%s %u\n", " Image height= ", imageheight);
- printf("%s %u\n", " Bits per Sample= ", bitspersample);
- printf("%s %u\n", " Compression= ", compression);
- printf("%s %d\n", " Photometric= ", photomint);
- printf("%s %u\n", " Strip offsets= ", *offset);
- printf("%s %u\n", " Samples per pixel= ", samplesperpixel);
- printf("%s %lu\n", " Rows per strip= ", rowsperstrip);
- printf("%s %lu\n", " Strip byte counts: ", *stripbytecounts);
- printf("%s %u\n", " Planar Configuration: ", plcf);
-
- printf("\n%s %s\n", " Description: ", description);
