ttfSizeUnicode function

int ttfSizeUnicode(
  1. Pointer<TtfFont> font,
  2. Pointer<Uint16> text,
  3. Pointer<Int32> w,
  4. Pointer<Int32> h,
)

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

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.

\param font the font to query. \param text text to calculate, in UCS-2 encoding. \param w will be filled with width, in pixels, on return. \param h will be filled with height, in pixels, on return. \returns 0 if successful, -1 on error.

\since This function is available since SDL_ttf 2.0.12.
