Is it possible (and how) to move a layer by half pixel (or other float values). I'm drawing a small image where moving a single pixel is too noticeable.

Increase (scale) the size of the entire image by 2, move the layer over 1 pixel, and then scale the entire image back down. Make sure the image support anti-aliasing.

I was about to suggest moving 1 pixel and halfing the intensity of it, and fiddling with it from there. But your method accomplishes it undoubtedly more accurately and easily. Nice! – Aeo Jan 19 '11 at 15:04
Nice. The result after linear interpolation is a slightly blurry, but the Sharpen filter fixed that up. – Lie Ryan Jan 19 '11 at 15:22

When upscaling, don't use interpolation. That way you'll get more accurate results. @LieRyan – oKtosiTe Jan 20 '11 at 10:23
