1996.12.18 10:42 "Problems with libtiff v3.4", by Benoit Chausserie-lapree
Hello,
I am using the TIFF library (libtiff, version 3.4) on a SUN station :
Sun4u/168 Mhz, Solaris 2.5.2.
With libtiff I cannot read TIFF files crated on a DEC-ALPHA station :
- the characteristics of the TIFF files are the following :
Header : it specifies the 'II' code (little endian : LSB first)
ImageWidth (tag code = 100 hex) = 17,
ImageLength (tag code = 101 hex) = 17,
BitsPerSample (tag code = 102 hex) = 16 (2 bytes per pixel)
StripOffsets (tag code = 111 hex) = offset of the strip in the file,
SamplesPerPixel (tag code = 115 hex) = 1 (1 component per pixel)
StripByteCount (tag code = 117 hex) = 578
- when reading the value of each pixel of the image on my SUN station with
the libtiff functions (with TIFFReadRawStrip), those are always interpreted
LSB-MSB and not MSB-LSB as they should on the SUN ;
- the tag values are correctly interpreted (e.g. with TIFFGetFied).
Where is the problem ?
Thank you in advance for your response,
Best Regards
Benoit Chausserie-Lapree,
