Rosie J Posted October 23, 2020 Share Posted October 23, 2020 When I make lineart, I often use the Magic Wand tool to select the lines themselves if I want to move part of the lineart without erasing and redrawing. The default Tolerance (50%) does not work; it selects only the darkest pixels in the lines and leaves behind a grayish shadow on either side of the line's former location. I am using the Line/Curve tool set to Spline for most of the lineart, and my Paintbrush is set at maximum Hardness, but there appears to be no way to get a perfectly black and white image with the Line/Curve tool. (I don't have a functional tablet and stylus at the moment, so the Pencil tool is mostly useless to me at this time.) "Not a problem," I thought. "I'll just set the Tolerance higher so Magic Wand will grab the whole line, not just the middle of it." Which I did. And then I noticed something very strange. The Magic Wand selected all the lines I'd drawn, as I expected. It also selected what appeared to be every stroke of the Eraser tool that I had used when making the lineart. All over the image were invisible brushstrokes, outlined in the 'marching ants' selection, that I recognized as being where I had erased lines that I hadn't been able to move. I double checked that my eraser's Hardness and Opacity were set to maximum, they had been all along. I had used the eraser set to (I think) 5 pixels, while all the lines had been drawn with the Line/Curve tool set to 2 pixels. It appeared that the eraser tool was leaving smudges of not-quite-transparent pixels wherever I used it--pixels the Magic Wand could see but I couldn't. Setting my eraser size larger (13 pixels if I recall right) seems to have gotten rid of these smudges. In hindsight I realize I should have taken a screenshot before doing so, but I found an area that still had some smudging in places with too many lines too close together to use the 13-pixel-wide eraser and took two screenshots (attached): one of the image as it appeared to me and one with Magic Wand used on the lines at somewhere between 60 and 85% tolerance. In a nutshell, the problem appears to be that the eraser, even set to 100% Hardness and 255 Opacity (Alpha), is not completely erasing pixels where it is used, at least when it is less than ten pixels wide.
