Dear Mr. Behrmann, 

thank you for your reply to the problem I put forward.

> I tested your image with CinePaint and it gave the following

> pixeltest.tif: Read error at scanline 240; got 61440 bytes, expected

I get similar error messages when I try to open that particular tif in 
Scribus, which I have compiled against libtiff 3.7.4:

/home/tobias/Pictures/pixeltest.tif: DumpModeDecode: Not enough data for 
scanline 0.
TIFFFillStrip: /home/tobias/Pictures/pixeltest.tif: Read error on strip 15; 
got460800 bytes, expected 461180.
TIFFFillStrip: /home/tobias/Pictures/pixeltest.tif: Read error on strip 16; 
got430080 bytes, expected 491900.
....

Unfortunately the rendering on screen (in Scribus) remains incorrect as in the 
screenshot mentioned in the mail before. The developer of Pixel has fixed the 
tiff output meanwhile, so the Pixel tiff output will be more standard 
conformant in future. This solves the problem at its origin - thanks to the 
help in this list.

Yours sincerely
