ttfRenderUtf8ShadedWrapped function

Pointer<SdlSurface> ttfRenderUtf8ShadedWrapped(Pointer<TtfFont> font, String? text, SdlColor fg, SdlColor bg, int wrapLength,)

Render word-wrapped UTF-8 text at high 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 specified background color, while other pixels have varying degrees of the foreground color. This function returns the new surface, or NULL if there was an error.

Text is wrapped to multiple lines on line endings and on word boundaries if it extends beyond wrapLength in pixels.

If wrapLength is 0, this function will only wrap on newline characters.

You can render at other quality levels with TTF_RenderUTF8_Solid_Wrapped, TTF_RenderUTF8_Blended_Wrapped, and TTF_RenderUTF8_LCD_Wrapped.

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

\since This function is available since SDL_ttf 2.0.18.
