Thank you, Dethe, for a very timely post. I recently got interested in playing with images in Python and I was looking for a way to draw translucent polygons. I was using PIL, but not having any success with the built-in transparency feature. I think it’s kind of buggy.

I’d like to see your code in toto, but the link above seems to be broken.

Any benchmarking on these three approaches? I’ve started implementing my own version of Roger Alsing’s idea using aggdraw+PIL and find it a bit slow. However, I might not doing things the right way.

Also: the link to your test file containing the code does not work.

mermaldad, I apologize for the slow response both in approving your comment and in answering it. For the first, I thought I had already approved it, for the second, I missed where you said the link was broken. All I can say in my defence is that both home and work have been crazy for the past month, but since that’s nearly always the case, it’s not much of an excuse.

In any case, I have fixed the link. I think Apache was trying to treat the .py file as an executable instead of sending it. My quick fix was to post a zipped version instead.

Thanks for your comments and patience.

Hi Andre, good to hear from you. I’m afraid I haven’t done any benchmarks yet, but I have fixed the link. Sorry about that. Thanks for letting me know!
