[OpenJDK 2D-Dev] RFR: 8238942: Rendering artifacts with LCD text and fractional metrics

Bug: https://bugs.openjdk.java.net/browse/JDK-8238942 webrev: http://cr.openjdk.java.net/~prr/8238942/ As discussed in the bug, we are missing padding in the code that takes an LCD glyph from freetype and caches it in the 2D glyph cache. This padding is used in subpixel positioning with fraction

Hi, Phil. Could you please clarify these lines, from the patch it is unclear what they should do. "Why" + glyphInfo->topLeftX -= 1; + // WHY NOT ADD ? + glyphInfo->width += 1; On 2/11/20 8:15 pm, Philip Race wrote: Bug: https://bugs.openjdk.java.net/browse/JDK-8238942 webrev: http://cr.openjdk

Change looks good to me. And we have good amount of time to notice any pixel accuracy issues. Thanks, Jay > On 12-Feb-2020, at 9:45 AM, Philip Race wrote: > > Bug: https://bugs.openjdk.java.net/browse/JDK-8238942 > webrev: http://cr.openjdk.java.net/~prr/8238942/ > > As discussed in the bug, w
