Member Function Documentation
◆ render_info_labels()
|
pure virtual |
To be implemented by a derived class to return the strings used in GlyphRenderCostInfo::m_value; The pointer behind each of the string in the return c_array returned are required to stay valid even after the GlyphRenderData is deleted. The expectation is that the returned c_array is just c_array wrapping over a static constant array of string.
Implemented in fastuidraw::GlyphRenderDataRestrictedRays, fastuidraw::GlyphRenderDataBandedRays, and fastuidraw::GlyphRenderDataTexels.
◆ upload_to_atlas()
|
pure virtual |
To be implemented by a derived class to upload data to a GlyphAtlas.
- Parameters
-
atlas_proxy GlyphAtlasProxy to which to upload data attributes (output) glyph attributes (see Glyph::attributes()) render_costs (output) an array of size render_info().size() to which to write the render costs for each entry in render_info().
Implemented in fastuidraw::GlyphRenderDataRestrictedRays, fastuidraw::GlyphRenderDataBandedRays, and fastuidraw::GlyphRenderDataTexels.
