TTF_SizeUNICODE

Calculate the dimensions of a rendered string of UCS-2 text.

Syntax

int TTF_SizeUNICODE(TTF_Font *font, const Uint16 *text, int *w, int *h);

Function Parameters

font

the font to query.

text

text to calculate, in UCS-2 encoding.

w

will be filled with width, in pixels, on return.

h

will be filled with height, in pixels, on return.

Return Value

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.

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.

Version

This function is available since SDL_ttf 2.0.12.
