(This function is part of SDL_ttf, a separate library from SDL.)

TTF_RenderUNICODE_Blended_Wrapped

Render word-wrapped UCS-2 text at high quality to a new ARGB surface.

Header File

Syntax

SDL_Surface * TTF_RenderUNICODE_Blended_Wrapped(TTF_Font *font,
                const Uint16 *text, SDL_Color fg, Uint32 wrapLength);

Function Parameters

TTF_Font *	font	the font to render with.
const Uint16 *	text	text to render, in UCS-2 encoding.
SDL_Color	fg	the foreground color for the text.
Uint32	wrapLength	the text is wrapped to multiple lines on line endings and on word boundaries if it extends beyond this value in pixels.

Return Value

(SDL_Surface *) Returns a new 32-bit, ARGB surface, or NULL if there was an error.

Remarks

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.

Please note that this function is named "Unicode" but currently expects UCS-2 encoding (16 bits per codepoint). This does not give you access to large Unicode values, such as emoji glyphs. These codepoints are accessible through the UTF-8 version of this function.

You can render at other quality levels with TTF_RenderUNICODE_Solid_Wrapped, TTF_RenderUNICODE_Shaded_Wrapped, and TTF_RenderUNICODE_LCD_Wrapped.

Version

This function is available since SDL_ttf 2.0.18.
