PaintNetRus Posted April 11, 2017 Share Posted April 11, 2017 (edited) - Create new layer - Use Gradient tool - Enable Antialiasing for Gradient tool - Make a Gradient in center of layer then - Use Magic Wand tool - Set Tolerance 0% for Magic Wand tool - And select an area outside the gradient so You see that Dithering for Gradient tool in Paint.net is broken Anti-aliasing is applied to the entire layer, this is incorrect Anti-aliasing should only be applied in the gradient area, and should not extend beyond its area Look attached files Edited April 11, 2017 by PaintNetRus Quote Link to comment Share on other sites More sharing options...
PaintNetRus Posted April 11, 2017 Author Share Posted April 11, 2017 (edited) Gradients created in other Graphic editors, for comparison with paint.net You see, GIMP and Photoshop use anti-aliasing, they do not have this problem Spoiler Edited April 11, 2017 by PaintNetRus Quote Link to comment Share on other sites More sharing options...
PaintNetRus Posted April 11, 2017 Author Share Posted April 11, 2017 (edited) A real use case - Make Rectangle - Use Gradient Tool - Enable Transparency Mode for Gradient Tool (set Black and White colors) - Make the rectangle part transparent then - Use Magic Wand tool - Set Tolerance 0% for Magic Wand tool - And select an area outside the Rectangle so You see that the part of the rectangle is not completely transparent Expected Result, that the transparent part will be completely transparent, and with Magic Wand Tool you can select the actual visible part of the rectangle.

IRON67 Posted April 11, 2017 Share Posted April 11, 2017 (edited) I think, what you call "outside" is in fact still inside the gradient. Edited April 11, 2017 by IRON67 Quote Link to comment Share on other sites More sharing options...

IRON67 Posted April 11, 2017 Share Posted April 11, 2017 (edited) However ... I can't reproduce it. The only thing is, that the "nearly" complete transparent edge isn't a straight edge, but a little bit pixelated. That*s, what I expected.

Rick Brewster Posted April 11, 2017 Share Posted April 11, 2017 I think someone reported this awhile ago but the bug is in my old database that I've since discarded. So I've filed a new one over at github. Thanks!

Eli Posted April 11, 2017 Share Posted April 11, 2017 @PaintNetRus If you disable antialiasing when creating the gradient you should not have the problem when using the Magic Wand at 0 % Tolerance. 1 Quote Link to comment Share on other sites More sharing options...
