Description Volga 2018-11-10 07:12:25 UTC
Description:
This is similar to bug 104403, but for fonts with CBDT/sbix tables instead (https://docs.microsoft.com/zh-cn/typography/opentype/spec/cbdt https://docs.microsoft.com/zh-cn/typography/opentype/spec/sbix). This might be a trickier as instead of rendering layered glyphs with different colors we will need to render raster graphics. We already have decent raster image support, but LibreOffice doesn’t make use of it from a low level as text rendering in VCL. Since HarfBuzz got support in version 2.1.0, it’s possible to render color glyphs via accessing these tables.
