extract_font_range

Extracts a range of characters from a font.

Description

FONT *extract_font_range(FONT *f, int begin, int end)
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the font. Example:
      FONT *myfont;
      FONT *capitals;
      FONT *fontcopy;
      ...
      /* Create a font of only capital letters */
      capitals = extract_font_range(myfont, 'A', 'Z');

/* Create a copy of the font */ fontcopy = extract_font_range(myfont, -1, -1); ... destroy_font(capitals); destroy_font(fontcopy);
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to avoid memory leaks.
