[BUG]Issue on transparent background with ImageBufAlgo.over #4474
Comments
Can you provide links to the exact png files that exhibit the error? |
Sure |
Doesn't it look like the sun image you're using in your examples is not the same image as the one you sent us? So are we comparing apples to apples? The sun image you sent has an outline and some kind of reflective/shaded appearance, whereas the one you keep posting does not. Are those different images? So I'm not sure if we're really testing the same thing. Can you either send us the file you're really using, or else test on your end using the same file you sent to us? I don't think we've yet established that the behavior is incorrect for the particular values in the file. |
Hi, just pinging this issue. I'm still confused about whether there's really a bug here and if we've got a proper apples-to-apples test. |
Describe the bug
While using
ImageBugAlgo.over(fg, bg)
If fg is a half transparent image with a fully transparent background, the background part show a color on it.
