Bloom effect discussion
arose opened this issue · comments
I just want to report a few differences i noticed on this comparison
- black background snapshot
- transparent background composed on gimp with both white and black background
- white background snapshot
I'm wondering if it is possible to enhance the effect of blooming on opaque background to uniform it to the tranpsarent backgorund?
Also is it possible to apply a better bloom smoothing effect that sometimes could be useful? (maybe only when exporting snapshots if this would lead to performances issues)

If you do a canvas with transparent background and have a black background div underneath it, are the artifacts also visible like in your GIMP example?

@dsehnal In this case I'm seeing it without artifacts.
I further checked in GIMP and have found that I need to change color space mode from linear to perceptual in order to get the correct result, if I correctly recall I had the same problem with common transparent objects. My bad, I should have remembered this.
I'm not sure why GIMP is not using the correct color space by default though. The default ubuntu image viewer opens the image correctly.
