Description __ 2007-04-24 14:38:36 UTC 
The blur tool blurs dark colours over the top of light ones. It's algorithm appears to favour dark colours when they are included in the blur.

I have made a video of it here: http://schalken.wubbles.net/gimpblurtooldarkoverlightbug.ogg

From my understanding, the average lightness of a given image should always remain constant as it is blurred.

I don't see anything wrong in that video. Perhaps it would make more sense to discuss this on the mailing-list. If we decide that there's a problem, we can still open a bug report then.

Okay I've sent it to gimp-developer

	* app/paint-funcs/paint-funcs.c (convolve_region): round pixel values
	instead if just casting the float to an integer. Fixes bug #432978.

Is this bug officially fixed? Absolutely no more darkness emerging from the blur tool?

I will attempt a compile from cvs this weekend.
