Hi Jacek, I would prefer that the bug in tifftopnm should be fixed. scanimage does not write a wrong value to the fillorder tag because is does not write the fill order tag at all. The fillorder tag is not a required tag. And the default value for fillorder is 1. So if the tool tifftopnm assumes a value of 0 this is wrong. If someone wants a more flexible output for TIFF, libtiff could be used. But now only uncompressed TIFF is created. So we don't need an additional dependency on the libtiff-package. This might be available on most Linux machines. But for other Unix-System you may need to install it.
