TTF_MeasureString

Calculate how much of a UTF-8 string will fit in a given width.

Header File

bool TTF_MeasureString(TTF_Font *font, const char *text, size_t length, int max_width, int *measured_width, size_t *measured_length);

TTF_Font *	font	the font to query.
const char *	text	text to calculate, in UTF-8 encoding.
size_t	length	the length of the text, in bytes, or 0 for null terminated text.
int	max_width	maximum width, in pixels, available for the string, or 0 for unbounded width.
int *	measured_width	a pointer filled in with the width, in pixels, of the string that will fit, may be NULL.
size_t *	measured_length	a pointer filled in with the length, in bytes, of the string that will fit, may be NULL.

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

This reports the number of characters that can be rendered before reaching max_width.

This does not need to render the string to do this calculation.

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

This function is available since SDL_ttf 3.0.0.
