On upgrading PHP to version 8 from 7.4 we noticed the following issue notifications:
Deprecated function: Implicit conversion from float 10.5 to int loses precision in image_gd_adjustlevels() (line 1195 of .../contrib/imagecache_actions/coloractions/imagecache_coloractions.module).
Deprecated function: Implicit conversion from float 27.359375 to int loses precision in image_gd_coloroverlay() (line 413 of .../imagecache_actions/coloractions/imagecache_coloractions.module).I've attached the patch file that addressed the issue for us.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Here is the alternate approach with rounding to the nearest integer. I have also removed the rounding of the last parameter ($source['alpha']), as this should be an integer (see the docs for imagecolorsforindex()).
