TTF_SizeText

Calculate the dimensions of a rendered string of Latin1 text.

Header File

Syntax

int TTF_SizeText(TTF_Font *font, const char *text, int *w, int *h);

Function Parameters

TTF_Font *	font	the font to query.
const char *	text	text to calculate, in Latin1 encoding.
int *	w	will be filled with width, in pixels, on return.
int *	h	will be filled with height, in pixels, on return.

Return Value

(int) Returns 0 if successful, -1 on error.

Remarks

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

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

You almost certainly want TTF_SizeUTF8() unless you're sure you have a 1-byte Latin1 encoding. US ASCII characters will work with either function, but most other Unicode characters packed into a const char * will need UTF-8.

Version

This function is available since SDL_ttf 2.0.12.
