Hello all,
I stumbled upon something that finds me vaguely recalling a mention in the past of some sort of "1 pixel" problem in Photoshop. I know even that description is vague in and of itself, so I’ll just describe what I’ve encountered:
I created a 100×100 pixel new image with a white background, selected the right half exactly (50×100) and filled that area with solid black using the Fill Tool options set at 100% opacity and 0 tolerance. The result should have been an edge-to-edge fill of RGB = 0/0/0, yet I found the color sampling in the Info palette indicated RGB = 15/15/15 for the last 1 pixel column at the left and right edges of the black-filled area.
Moreover, if the selction marquee was still active around the filled region and I reapplied the Fill Tool, that 15/15/15 value was reduced to 1/1/1 and would only "zero out" once I applied the Fill Tool once more. However, if I first deselected the area and then filled the 15/15/15 region, it did "zero out" correctly.
This behavior was seen in both PS7 and PSCS. While I don’t consider it all too significant, it nonetheless begs the question, WHY?
Does this have to do with color value errors introduced by the active marquee around a selected area?
Thanks,
Daryl
