frio Posted February 23 Share Posted February 23 Some blur effects cause a misplaced, garbled 16 pixel tall slice of the image to appear overlapping the top area of the image when used with 0 strength, instead just leaving the unblurred image in place. Where the garbled pixels come from changes often between different preview renders and the final render. The effects have other meaningful uses even when used with 0 blur strength. I think this may be a bug in PDN itself since it reproduces in effects by different authors from many years apart, maybe they call some kind of a built-in blur function? It did not happen before version 5.0. Plugins I've found to be affected are Gaussian Blur+ by BoltBait and Tweak Transparency v2 (and v1, which is apparently no longer available for download) by Red Ochre. Steps to reproduce: make any image of any size with enough distinct areas, a diagonal gradiant is fine. Apply one of the above effects at strength 0.

Rick Brewster Posted February 23 Share Posted February 23 Yeah I can reproduce this with Gaussian Blur+ very easily. I'll look into it. cc @BoltBait Quote The Paint.NET Blog: https://blog.getpaint.net/ Donations are always appreciated! https://www.getpaint.net/donate.html Link to comment Share on other sites More sharing options...
Solution Rick Brewster Posted February 23 Solution Share Posted February 23 Okay I figured out what was wrong and I fixed it. It'll be working again in the 5.0.3 update. 1 1 Quote The Paint.NET Blog: https://blog.getpaint.net/ Donations are always appreciated! https://www.getpaint.net/donate.html Link to comment Share on other sites More sharing options...

Or, sometimes in complex effects, you just don’t want to add a blur at the end. See my Outline Object effect. 1 Quote Click to play: Download: BoltBait's Plugin Pack | CodeLab | and how about a Computer Dominos Game Link to comment Share on other sites More sharing options...
Rick Brewster Posted February 23 Share Posted February 23 Using 0 blur radius, even for the built-in blurs, is a convenient way to see how the image looks without the blurring.

The Tweak Transprency plugin is a fairly bread&butter plugin for my uses, and using it with 0 blur but adjusting the min/max transprency values has very useful effects. I know I could achieve similar results with the Curves+ adjustment with alpha channel only, but you know, once you get used to a workflow and something seems amiss and happens in other places too... 1 Quote Link to comment Share on other sites More sharing options...
Red ochre Posted February 23 Share Posted February 23 Tweak transparency v2: Wow - I haven't used it myself for about 10 years! (It is still available... there's a link right at the bottom of my plug-in pack first post). I don't remember if there ever was a v1 published?🙄 For adjusting alpha I wrote 'alpha threshold' to replace it (in my pack)... that doesn't use the Gaussian blur at all. ('Object edges' was written to replace Tweak transparency's edge colouring effect... still using the in-built Gaussian blur). Quote Red ochre Plugin pack..............

I don't remember if there ever was a v1 published?🙄 I'm pretty sure I have both, since the effects have different names (one calls itself v2, the other doesn't) and doesn't have the extra color settings/stuff. I prefer the more simple presumedly-v1, and since I also use the blur (I don't use it at strength 0 at all times) it's more useful to me than just alpha thresholds. Thanks to everyone involved with PDN and its plugins, in either case, it's been what, like 15 years now, and so, so many textures made.
