[Image-SIG] PIL losing attributes...
Mon, 07 Apr 2003 02:06:05 -0600
Hi. I'm using PIL to do some image manipulations. I like that the PIL
objects have attributes like format, size etc. My problem is...when I
apply some filter, say ImageChops.invert, or Image.transpose, it looses
the addributes. For example
> if DEBUG: print "Before transpose, format is: " + str(pil.format)
> pil = pil.transpose(Image.FLIP_LEFT_RIGHT)
> if DEBUG: print "After transpose, format is: " + str(pil.format)
the first output prints "JPEG" or "GIF" or whatever.
after the transpose, the output is "None"
I tried this with and without the str() wrapper. So...I'm guessing that
the copy that returned from the transpose (or other filters) is part of
the problem maybe? Do I need to use some kind of copy constructor or
something? The same thing happens with the size attribute, or the info
dictionary that I add.
Any hints at all on this would be very appreciated. It's really
throwing a wrench into my app.
