try converting the image to RGB first, and use resize(ANTIALIAS) on
the RGB image before
I forgot to take of the _t function, so the first lines should be:
CROSS = 'Cross'
ROUNDED = 'Rounded'
SQUARE = 'Square'

The following code preferably uses cache (just a simple python
dictionary) to avoid the overhead of generating the same transparency
masks. So typical use would be:
cache = {}
for image in images:
thumbnail = image_round(image.thumbnail(size, filter), cache, radius)
Hi all,
Just started using PIL. I'm attempting to resize a .gif image to a smaller
size, keeping the height/width proportional. The resize works, but the
resulting image is very grainy. Resizing the same image with ImageMagick's
convert utility produced a far better quality image. I'd rather

Fredrik, thanks for the reply. I am in fact converting to RGB

hi Andy
Here's the resized gif with the original code I pasted. You'll see a
bunch of 'dots' throughout the image:

PIL uses the so-called web palette by default. Your image uses
#fdfdfd for white, but the web palette uses #ff. So it dithers to
Hey Douglas,
I interpreted your response as a setting to change to make this
specific image resize better. I'm using PIL to resize images that
users upload to my website. Since I don't have control over the
media, I need generic settings that will be good for all users. What
settings would you

Thanks Douglas. Just tested it out, and the quality has improved
