Fisherman's Friend Posted October 21, 2007 Share Posted October 21, 2007 Hello everyone. Recently I had massive problems with the Gaussian Blur when I used it on selections. The point is that it blurs only the selection, of course, but uses the entire (not selected) picture as source for the image modification. Here are some simple examples as demonstration: The selection: And now the problem: See the red color of our B coming in? That's the point! In this case it looks rather harmless, but when used with complex pictures it creates rather nasty things. As you can see, darkness is invading the selection, created by the not selected part of the picture. I tried to copy the selection and to paste it in a new layer and then running the blur on it, but in every case the surrounding alpha was now the problem. The funny thing was that the blur got weaker when I increased the blur value (because of he alpha). What I want is just a "Gaussian Blur +", which, as you can imagine, uses only the current selection as base. I think this is possible, as MadJik did such a thing for his Twistz effect on request (viewtopic.php?f=16&t=20508&start=0; thanks again MadJik). Also I think it would not be that complicated as you can build the effect using the normal Gaussian Blur source. For me, code usable with codelab is fine enough. I would really be glad to get this thing working. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
