ttfRenderTextSolid function ttf

Pointer<SdlSurface> ttfRenderTextSolid(Pointer<TtfFont> font, String? text, int length, SdlColor fg,)

Render UTF-8 text at fast quality to a new 8-bit surface.

This function will allocate a new 8-bit, palettized surface. The surface's 0 pixel will be the colorkey, giving a transparent background. The 1 pixel will be set to the text color.

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_Solid_Wrapped() instead if you need to wrap the output to multiple lines.

This will not wrap on newline characters.

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

\param font the font to render with. \param text text to render, in UTF-8 encoding. \param length the length of the text, in bytes, or 0 for null terminated text. \param fg the foreground color for the text. \returns a new 8-bit, palettized surface, or NULL if there was an error.

\threadsafety This function should be called on the thread that created the font.

\since This function is available since SDL_ttf 3.0.0.
