ttfRenderGlyph32Blended function

Pointer<SdlSurface> ttfRenderGlyph32Blended(Pointer<TtfFont> font, int ch, SdlColor fg)

Render a single 32-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.

This is the same as TTF_RenderGlyph_Blended(), but takes a 32-bit character instead of 16-bit, and thus can render a larger range. If you are sure you'll have an SDL_ttf that's version 2.0.18 or newer, there's no reason not to use this function exclusively.

You can render at other quality levels with TTF_RenderGlyph32_Solid, TTF_RenderGlyph32_Shaded, and TTF_RenderGlyph32_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 2.0.18.
