I'll stay out of this issue, though I suspect that 24bit data should not be byte swapped.

The latest libtiff does byte-swap 24-bit data because Chris Cox at Adobe claims that this is what the TIFF specification implies and because it is necessary to read/write the new 24-bit floating format from Adobe Photoshop CS2. I must admit to being dubious about this claim, and I believe that Joris is as well. But if Adobe Photoshop CS2 does it, by-golly it must be right!

The 24-bit sample file is not byte-swapped because libtiff was not swapping at the time.

Folks,

24-bit per sample images from the test package now updated to be compliant with above. New images available in CVS and will be packaged and uploaded with the next libtiff release.

Andrey

PS.

Thanks to GraphicsMagick, it is really easy to create almost any kind of TIFF image!
