7       library.

SYNOPSIS

10       #include <allegro.h>

13       FONT *merge_fonts(FONT *f1, FONT *f2)

DESCRIPTION

16       This function merges the character ranges from two fonts and returns  a
17       new  font  containing  all characters in the old fonts. In general, you
18       cannot merge fonts of different types (eg, TrueType fonts and bitmapped
19       fonts),  but  as a special case, this function can promote a monochrome
20       bitmapped font to a color font and merge those. Example:
21
22          FONT *myfont;
23          FONT *myfancy_font;
24          FONT *lower_range;
25          FONT *upper_range;
26          FONT *capitals;
27          FONT *combined_font;
28          FONT *tempfont;
29          ...
30          /* Create a font that contains the capitals from  */
31          /* the fancy font but other characters from myfont */
32          lower_range = extract_font_range(myfont, -1, 'A'-1);
33          upper_range = extract_font_range(myfont, 'Z'+1, -1);
34          capitals = extract_font_range(myfancy_font, 'A', 'Z');
35
36          tempfont = merge_fonts(lower_range, capitals);
37          combined_font = merge_fonts(tempfont, upper_range);
38
39          /* Clean up temporary fonts */
40          destroy_font(lower_range);
41          destroy_font(upper_range);
42          destroy_font(capitals);
43          destroy_font(tempfont);
44

RETURN VALUE

46       Returns a pointer to the new font or NULL on error. Remember  that  you
47       are  responsible  for destroying the font when you are finished with it
48       to avoid memory leaks.
