Hello Chaitra,
We provide a dedicated version of our Platform Packages optimized to be integrated with an external TrueType font engine, e.g. FreeType. In such case, all fonts used in your project are not generate as built-in glyph data. Instead, the glyph rasterization occurs by the external TTF engine. The use of these packages is subject to a separate license.
Does it answer your question?
Best regards
Paul Banach
