Commit: 850944e6cda763f099652bf97d52d22f1deb5daa Author: Jeroen Bakker Date: Mon Oct 19 11:29:47 2020 +0200 Branches: master https://developer.blender.org/rB850944e6cda763f099652bf97d52d22f1deb5daa
Image: Export emissive colors in 3 channel PNG images Related to T81199. When saving a rendered image with transparency (RGBA) to a 3 channel PNG image the emissive colors were not exported. This change adds the emissive colors to the written file. NOTE: this does not fix the limitation of writing emissive colors to a 4 channel PNG file as the file format does not support this. =================================================================== M source/blender/imbuf/intern/imageprocess.c =================================================================== diff --git a/source/blender/imbuf/intern/imageprocess.c b/source/blender/imbuf/intern/imageprocess.c index 6ad69e72b4f..f8029c08bad 100644 --- a/source/blender/imbuf/intern/imageprocess.c +++ b/source/blender/imbuf/intern/imageprocess.c @@ -458,17 +458,8 @@ void IMB_alpha_under_color_float(float *rect_float, int x, int y, float backcol[ float *fp = rect_float; while (a--) { - if (fp[3] == 0.0f) { - copy_v3_v3(fp, backcol); - } - else { - float mul = 1.0f - fp[3]; - - fp[0] += mul * backcol[0]; - fp[1] += mul * backcol[1]; - fp[2] += mul * backcol[2]; - } - + const float mul = 1.0f - fp[3]; + madd_v3_v3fl(fp, backcol, mul); fp[3] = 1.0f; fp += 4; _______________________________________________ Bf-blender-cvs mailing list Bf-blender-cvs@blender.org https://lists.blender.org/mailman/listinfo/bf-blender-cvs
