Noel, thank you! I am beginning to understand.
Currently, in my design, the user cannot specify the colour space that they
will save the data in.
I think this needs to be implemented. Currently, we always assume sRGB.
But, for grayscale, this may not be the best approach, as you mentioned.
Following your suggestion, for TIFF, I am now simply storing the ICC
information in the TIFF file and NOT
applying a transform. I will also look into doing this for PNG.
For other formats, I will need to allow the user to specify the gamma and
white point, I suppose.
