KrisVDM Posted August 19, 2010 Share Posted August 19, 2010 How to reproduce: - Start from a new image - Set primary color to red: 153, green: 179, blue: 204 - Use Paint Bucket to fill entire image with this color - Choose Paintbrush tool, set Brush width to 200, Fill to solid color, antialiasing enabled, normal blending - Draw a bit - Choose Magic Wand, set selection mode to replace, flood mode to contiguous, Tolerance to zero - Click anywhere in the image where you did not draw Expected outcome: everyting is selected Actual outcome: everything is selected, except some pixels left at the edges of the brush circles PDN version: 3.5.5 running on Windows 7 64 bit I expect there is a rounding error in the normal blending of the atialiased pixels. Either the antialiased pixels do not have the same color (they are expected to have a different alpha, but the same RGB), or the alphablend has a rounding problem. Blending a color with itself should yield the same color. I often use this technique to remove noise in what should be solid color regions. Looks like that's not a good idea...
