jlous Posted June 13, 2008 Share Posted June 13, 2008 [PDN 3.31] There is something strange with he vector rasterizer: When drawing ellipses or diagonal lines with antialiasing on, it is impossible to get a symmetrical result. Circles for example, tend to be slightly heavier downwards and to the right. To reproduce: - use an even white background for best effect - zoom in a lot (800% or so) - select ellipse tool and turn on anti-aliasing - draw a tiny black circle, for exanple 6 pixels across. - Notice how no four 'sides' or corners' are alike. Similarly, you cannot make a 45-degree line that is symmetrical about its own centerline, regardless of line thickness. I use PDN a lot for making small web graphics elements. This kind of thing is annoying and unprofessional-looking enough that I often resort to clunky workarounds like copying and flipping to get it pixel-perfect. But this really shouldn't be necessary.
