Hello all of you,
I am now to this Image module, so my question is to get a flavor of
things;-).
I want to do the following:
. have a given picture (jpg or bmp)
. bring it into 32 bit integer or floating point space
. perform on each pixel a gamma (different for each RGB channel)
. perform a 3*3 color transform matrix on each pixel
. perform on each pixel a gamma of 2.2 (to bring it back to xRGB space)
. convert back to jpg or bmp (in 8 bit space I assume).
I have looked at http://www.pythonware.com/library/pil/handbook/ , but I
seem not to find the things I want. I am using PIL 1.1.5 with python 2.2
Thanks for your feedback.
All the best,
Victor
