Tobias,

just to add, I tested your image with CinePaint and it gave the following errors:

....
pixeltest.tif: Read error at scanline 240; got 61440 bytes, expected
860540
pixeltest.tif: Read error at scanline 240; got 30720 bytes, expected
891260
....

CinePaint's tiff reader is linked on my system to libtiff-3.7.4 and reads the image to readable text form. The result looks good. An Update of libtiff should at least solve that broken tiff variant.

regards

Dear Mr. Van Damme,

thank you very much for your quick answer pointing to the origin of the problem.

The fact that some applications render this TIFF, is probably simply because they apply some robust StripByteCounts value correction in a case like this.

Is it possible to have this robust StripByteCounts value correction with libtiff-dependent applications automagically? Some script? Or has it already been implemented in libtiff version 3.7.4?

I will report the problem to the developer of Pixel.

Thanks again
