Good to hear it as it avoids some hard decisions. Per-pixel consistency is always the desired goal, but sometimes you have to look at what is possible to accomplish with the APIs we depend on and make some hard decisions. If it would take a work around technique that would take 100x as long

[OpenJDK 2D-Dev] Rotation per-pixel accuracy

Hi, The last two days I worked on text-rendering, and although major parts are missing (caching, optimizations, ...), it works already for no-AA and grayscale-AA'ed glyphs (I will look at subpixel-rgb later, frightens me somehow ;) ). I was able to solve the problem with the corrupted

Hi again, Are there rules that rendering has to be per-pixel consistent, with what should I compare to see wether my implementation works correct? Sorry about the traffic ... it seems different rounding errors were the cause for the different results, the rotated text was drawn to the BI at the
