            Bug ID: 121327
           Summary: Support multi-colored fonts using CBDT/SBIX tables
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: shanshandehongxing at outlook.com

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.
