Calculate how much of a UCS-2 string will fit in a given width.
int TTF_MeasureUNICODE(TTF_Font *font, const Uint16 *text, int measure_width, int *extent, int *count);| font | the font to query. |
| text | text to calculate, in UCS-2 encoding. |
| measure_width | maximum width, in pixels, available for the string. |
| count | on return, filled with number of characters that can be rendered. |
| extent | on return, filled with latest calculated width. |
Returns 0 if successful, -1 on error.
This reports the number of characters that can be rendered before reaching measure_width.
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.
This function is available since SDL_ttf 2.0.18.
