How to CREATE a transparent gif (or png) with PIL (python-imaging)

Question

Trying to create a transparent gif with PIL. So far I have this:

    from PIL import Image      img = Image.new('RGBA', (100, 100), (255, 0, 0, 0))     img.save("test.gif", "GIF", transparency=0) 

Everything I've found so far refers to manipulating an existing image to adjust it's transparency settings or overlaying a transparent image onto another. I merely want to create a transparent GIF (to then draw onto).

Answer 1

The following script creates a transparent GIF with a red circle drawn in the middle:

from PIL import Image, ImageDraw  img = Image.new('RGBA', (100, 100), (255, 0, 0, 0))  draw = ImageDraw.Draw(img) draw.ellipse((25, 25, 75, 75), fill=(255, 0, 0))  img.save('test.gif', 'GIF', transparency=0) 

and for PNG format:

img.save('test.png', 'PNG')
