ttfRenderTextLcd function

Pointer<SdlSurface> ttfRenderTextLcd(Pointer<TtfFont> font, String? text, SdlColor fg, SdlColor bg,)

Render Latin1 text at LCD subpixel quality to a new ARGB surface.

This function will allocate a new 32-bit, ARGB surface, and render alpha-blended text using FreeType's LCD subpixel rendering. This function returns the new surface, or NULL if there was an error.

This will not word-wrap the string; you'll get a surface with a single line of text, as long as the string requires. You can use TTF_RenderText_LCD_Wrapped() instead if you need to wrap the output to multiple lines.

This will not wrap on newline characters.

You almost certainly want TTF_RenderUTF8_LCD() unless you're sure you have a 1-byte Latin1 encoding. US ASCII characters will work with either function, but most other Unicode characters packed into a const char * will need UTF-8.

You can render at other quality levels with TTF_RenderText_Solid, TTF_RenderText_Shaded, and TTF_RenderText_Blended.

\param font the font to render with. \param text text to render, in Latin1 encoding. \param fg the foreground color for the text. \param bg the background 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 2.20.0.
