Jürgen / Bob,

Do we have other utilities that let the user pass raw mode values? I'd rather not have this in ppm2tiff if it is not an established pratice. Of course -a for append is fine.

It is true that supporting the same output selection options as 'tiffcp' is best. Quite a lot more work to implement though.


Best regards,

Sure. There are more - possibly useful - mode options, though. The list of options given in TIFFOpen(3TIFF) like l,b to change the byte order, m to disable memory mapped files, perhaps h to skip some parsing overhead (untested).

manual page for ppm2tiff (man/bmp2tiff.1 in the source tree) there would need to be an associated manual page update which at least refers to the

options are libtiff version dependent. (to be released soon)  Libtiff 4

offers more mode options.

Are you willing and able to send a patch for the manual page as well?
