ttfRenderUtf8BlendedWrapped function
Render word-wrapped UTF-8 text 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.
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_Shaded_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 32-bit, ARGB surface, or NULL if there was an error.
\since This function is available since SDL_ttf 2.0.18.
