Calculate how much of a Latin1 string will fit in a given width.
int TTF_MeasureText(TTF_Font *font, const char *text, int measure_width, int *extent, int *count);| font | the font to query. |
| text | text to calculate, in Latin1 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.
You almost certainly want TTF_MeasureUTF8() 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.
This function is available since SDL_ttf 2.0.18.
