Member Function Documentation

createTexture()

virtual void * GlyphRenderer::createTexture ( uint16_t width, uint16_t height )

pure virtual

Allocates an empty single-channel glyph texture. Returns an opaque handle.

Implemented in OgcGlyphRenderer, and WutGlyphRenderer.

destroyTexture()

virtual void GlyphRenderer::destroyTexture ( void * texture )

pure virtual

Destroys a texture created by createTexture().

Implemented in OgcGlyphRenderer, and WutGlyphRenderer.

drawFeature()

virtual void GlyphRenderer::drawFeature ( int16_t screenX, int16_t screenY, uint16_t width, uint16_t height, const PixelColor & color )

pure virtual

Draws a solid-color rectangle used for text decoration (underline/strike-through).

Implemented in OgcGlyphRenderer, and WutGlyphRenderer.

drawQuad()

virtual void GlyphRenderer::drawQuad ( void * texture, int16_t screenX, int16_t screenY, uint16_t width, uint16_t height, const PixelColor & color )

pure virtual

Draws a glyph texture as a quad tinted with color.

Implemented in OgcGlyphRenderer, and WutGlyphRenderer.

loadTextureData()

virtual void GlyphRenderer::loadTextureData ( void * texture, FT_Bitmap * bitmap )

pure virtual

Uploads a rasterized FreeType glyph bitmap into a texture from createTexture().

Implemented in OgcGlyphRenderer, and WutGlyphRenderer.
