Enabling color – DrawTextLayout
d2dContext->DrawTextLayout(
D2D1::Point2F(x, y),
m_layout.Get(),
D2D1_DRAW_TEXT_OPTIONS_CLIP | D2D1_DRAW_TEXT_OPTIONS_ENABLE_COLOR_FONT
);
Enabling color - DrawGlyphRun
d2dContext->DrawGlyphRun(…, glyphRun, … color, …);
Enabling color - DrawGlyphRun
colorlayers = dWrite->TranslateColorGlyphRun(…, glyphRun, …);
Foreach layer in colorLayers {
d2dContext->DrawGlyphRun(…, layer.GlyphRun, … layer.color, …);
