TTF_GetStringSizeWrapped

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

Header File

Defined in <SDL3_ttf/SDL_ttf.h>

Syntax

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

Function Parameters

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 wrap_width the maximum width or 0 to wrap on newline characters.
int * w will be filled with width, in pixels, on return.
int * h will be filled with height, in pixels, on return.

Return Value

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

Remarks

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.

Thread Safety

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

Version

This function is available since SDL_ttf 3.0.0.
