[Image-SIG] PIL 1.1.6 ImageFile.Parser destroys data for PngImagePlugin
Hi,
I'm new PIL user. I wanted utilize it in the PPM image comparison. I found the PIL usable fo
r our needs and wanted to distribute it for our needs. I have the PPM image with 0xFFFF Maxv
al (maximum color value). The object of the Image class loaded my PPM without any complain.
But after I saved it back on the dick I was surprised that the Maxval of saved image was of
256 (0xFF) value.
I started to debug the load procedure and found that PpmImageFile._open from PpmImagePlugin
method just ignores the Maxval parameter.
Q: Do I have some alternative to load and process the PPM image with 32-bit Maxval?
Thank you in advance.
Zachar
