merge_fonts
merge_fonts(3alleg4) Allegro manual merge_fonts(3alleg4)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 mono-
chrome 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.
