PIL rotate image colors (BGR -> RGB)

I have an image where the colors are BGR. How can I transform my PIL image to swap the B and R elements of each pixel in an efficient manner?

Solution

  • Assuming no alpha band, isn't it as simple as this?

    b, g, r = im.split()
im = Image.merge("RGB", (r, g, b))

    Edit:

    Hmm... It seems PIL has a few bugs in this regard... im.split() doesn't seem to work with recent versions of PIL (1.1.7). It may (?) still work with 1.1.6, though...
