Hello, I'd like to submit a patch for JDK-8210058. I'm not a Committer, so I'll need someone to sponsor this change.
The issue is related to the implementation of algorithmic italics in FreeType font scaler. At the moment it uses FT_GlyphSlot_Oblique, but its implementation doesn't take into account the glyph transform, previously set using FT_Set_Transform, and FreeType developers don't seem to have any interest in changing that (see https://savannah.nongnu.org/bugs/index.php?54565). The proposed solution is to include corresponding shear transform explicitly in matrix passed to FT_Set_Transform instead of using FT_GlyphSlot_Oblique. Proposed patch doesn't add any tests, as the change only impacts glyph rendering, and I couldn't think of a reliable way to test that automatically. Existing automated tests from OpenJDK pass after the fix. Issue: https://bugs.openjdk.java.net/browse/JDK-8210058 Webrev: http://cr.openjdk.java.net/~dbatrak/8210058/webrev.00/ Best regards, Dmitry Batrak
