Try to replace color in layer 1 (where the radish is), a black square will appear bordering the radish on the back, even if my background is transparent.
The continuous paint bucked wouldn’t help here so if i want to replace all the black border all i can do is replace the black color.
The top layer does almost nothing.
Tried the 8-connected thing but it made the selection go through the outline. I just filled in the inside of the reddish and made sure there was a separate color in the palate for black and transparency
If you add a transparency color to your palate, (and btw there are 2 colors in your border, black for the inside of the leaf and grey for the outside of the leaf and the radish body.) then it should work fine. Zippyshare.com - Video of it working.
you’re trying to replace index 0.
in that case replace colour will fill the area outside the image boundary with target colour. if you try to replace other indices, everything works as expected.
this seems to be a bug, because:
pixels outside image boundary are filled - there seems to be no reason for that.
when you use colour picker on surrounding areas, you will get transparent index colour (just as you would expect).
when replacing other indexes than #0, replace colour works fine.
