Frage

Is there a way to get rendered bitmap image using DirectWrite and Direct2D ?

Like FreeType2's FT_GlyphSlot->bitmap...

War es hilfreich?

Lösung

I think you can create a ID2D1Bitmap first, then use ID2D1Bitmap::CopyFromRenderTarget to copy the data from render target.

It is possible, and you don't need to use Direct2D for that. Use CreateGlyphRunAnalysis and then call GetAlphaTextureBounds to get resulting bitmap bounds, then allocated buffer and call CreateAlphaTexture. This fills your buffer with opacity mask for a glyph run you want to render.
