Synopsis

#include <allegro.h>

FONT *extract_font_range(FONT *f, int begin, int end)

Description

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);

Return Value

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.
