TTF_GetStringSizeWrapped - Calculate the dimensions of a rendered string of UTF-8 text.

Defined in SDL3_ttf/SDL_ttf.h

#include "SDL3_ttf/SDL_ttf.h"

bool TTF_GetStringSizeWrapped(TTF_Font *font, const char *text, size_t length, int wrap_width, int *w, int *h);

This will report the width and height, in pixels, of the space that the specified string will take to fully render.

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

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

	font		the font to query.
	text		text to calculate, in UTF-8 encoding.
	length		the length of the text, in bytes, or 0 for null terminated text.

wrap_width

the maximum width or 0 to wrap on newline characters.

	w		will be filled with width, in pixels, on return.
	h		will be filled with height, in pixels, on return.

Returns true on success or false on failure; call SDL_GetError() for more information.

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

This function is available since SDL_ttf 3.0.0.
