I am using Python tifftools library to modify and create DNG format image (tiff). I want to set all tiff tags individually. I am using tifftools.tiff_set function. It takes an argument setlist, which is a list of tuples, first element of the tuple is tag identifier (e.g. tifftools.Tag.XRESOLUTION, tifftools.Tag.CFAPATTERN...) and the second is actual value. How to obtain a list of possible tags identifiers without just guessing?
Or what is the alternative to this approach? Maybe different library?
You can find a complete list of TIFF tags in Tags for TIFF, DNG, and Related Specifications.
I think tifftools follow that specification but if you want to know exactly what constants it accept you could see its code, specifically constants.py .
