Automatic outline issue


#1

Hey everyone!

Since the last update, I’m having an issue with outline in Convolution Matrix. It didn’t occur every time and I’m not sure whats causing this, but when I delete all the invisible pixels outside the art and try again, the outline works fine. I’d checked with color picker if any of those pixels have a little color, but everything has the code “#000000 A0”.

Hi @LuisLudic, would you like to share your image with me at support@aseprite.org so I can give a try?

Other possibility to do an outline now (as v1.2.9 was just released) is using the Magic Wand tool and the Stroke option (S key) from Edit > Stroke menu:

Sure! I’ll send you the .ase file

Thanks @LuisLudic, I’ve just checked your file.

This is a known issue in how some filters work with completely transparent pixels (pixels with Alpha=0). And the outline convolution matrix has some problems when the RGB values are not black for pixels with Alpha=0.

With the Color Curve we can check the real color of transparent pixels:

See that there are some hidden non-black pixels. To fix this we can use the Magic Wand tool to select all transparent pixels, and press the Delete key (Edit > Delete menu):

Something that we need to fix in a future version in some way.

Thanks for replying, David! I’ll use that Magic Wand method until this bug gets fixed. :smiley:
