merge_fonts(3)                  Allegro manual                  merge_fonts(3)



NAME
       merge_fonts - Merges two fonts into one font. Allegro game programming
       library.

SYNOPSIS
       #include <allegro.h>


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

DESCRIPTION
       This function merges the character ranges from two fonts and returns a
       new font containing all characters in the old fonts. In general, you
       cannot merge fonts of different types (eg, TrueType fonts and bitmapped
       fonts), but as a special case, this function can promote a monochrome
       bitmapped font to a color font and merge those. Example:

          FONT *myfont;
          FONT *myfancy_font;
          FONT *lower_range;
          FONT *upper_range;
          FONT *capitals;
          FONT *combined_font;
          FONT *tempfont;
          ...
          /* Create a font that contains the capitals from  */
          /* the fancy font but other characters from myfont */
          lower_range = extract_font_range(myfont, -1, 'A'-1);
          upper_range = extract_font_range(myfont, 'Z'+1, -1);
          capitals = extract_font_range(myfancy_font, 'A', 'Z');

          tempfont = merge_fonts(lower_range, capitals);
          combined_font = merge_fonts(tempfont, upper_range);

          /* Clean up temporary fonts */
          destroy_font(lower_range);
          destroy_font(upper_range);
          destroy_font(capitals);
          destroy_font(tempfont);

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.
