ttfRenderGlyphBlended function

Pointer<SdlSurface> ttfRenderGlyphBlended(Pointer<TtfFont> font, int ch, SdlColor fg)

Render a single 16-bit glyph at high quality to a new ARGB surface.

This function will allocate a new 32-bit, ARGB surface, using alpha blending to dither the font with the given color. This function returns the new surface, or NULL if there was an error.

The glyph is rendered without any padding or centering in the X direction, and aligned normally in the Y direction.

Note that this version of the function takes a 16-bit character code, which covers the Basic Multilingual Plane, but is insufficient to cover the entire set of possible Unicode values, including emoji glyphs. You should use TTF_RenderGlyph32_Blended() instead, which offers the same functionality but takes a 32-bit codepoint instead.

The only reason to use this function is that it was available since the beginning of time, more or less.

You can render at other quality levels with TTF_RenderGlyph_Solid, TTF_RenderGlyph_Shaded, and TTF_RenderGlyph_LCD.

\param font the font to render with. \param ch the character to render. \param fg the foreground color for the text. \returns a new 32-bit, ARGB surface, or NULL if there was an error.

\since This function is available since SDL_ttf 2.0.12.
