Hi,
I'm evaluating pdf2img.exe command line image converter to convert PDF to tif - fax files.
I need to generate multi page, CCITT-G3/G4, 200x200, 1728X2200, min-is-white files.
problem 1: when I put "-multipage" the output files is always generated in CCITT-G4 mode (even for compress types 3,88882 & 88883), this is normal?
problem 2: I need the file to be min-is-white, the actual files are interpreted whit black and white reversed. how to make min-is-white files?
