I'm working on a project where I'm blending an image that is set on transparency. The non-transparent pixels are not near the edges of the bitmap.
It seems to me that when the Blur node (I'm using Gaussian) is blending transparent pixels with partly opaque pixels, it is using something like white instead of transparency?
View the attached image at full size in order to see the comparison.
It might seem minor, but it caused a bit of hair-pulling for my project, due to the difference. I'm trying to think of a workaround, but I can't think of a way.
