load_bitmap_font(3)		Allegro	manual		   load_bitmap_font(3)

NAME
       load_bitmap_font	 -  Grabs a font from a	bitmap file. Allegro game pro-
       gramming	library.

SYNOPSIS
       #include	<allegro.h>

       FONT *load_bitmap_font(const char *filename, RGB	*pal, void *param)

DESCRIPTION
       Tries to	grab a font from a bitmap. The bitmap can  be  in  any	format
       that load_bitmap	understands.

       The  size  of  each character is	determined by the layout of the	image,
       which should be a rectangular grid containing all the ASCII  characters
       from space (32) up to the tilde (126). The way the characters are sepa-
       rated depends on	the color depth	of the image file:

       paletted	(8 bit)	image file Use color 0 for the transparent portions of
       the characters and fill the spaces between each letter with color 255.

       High  (15/16 bit) and true (24/32 bit) color image file Use bright pink
       (maximum	red and	blue, zero green) for the transparent portions of  the
       characters  and	fill the spaces	between	each letter with bright	yellow
       (maximum	red and	green, zero blue).

       Note that in each horizontal row	the bounding boxes around the  charac-
       ters should align and have the same height.

       Probably	the easiest way	to get to grips	with how this works is to load
       up the `demo.dat' file and export the TITLE_FONT	into a PCX file.  Have
       a look at the resulting picture in your paint program: that is the for-
       mat a font should be in.

       Take care with high and true color fonts: Allegro will convert these to
       the  current  color  depth  when	you load the font. If you try to use a
       font on a bitmap	with a different color depth  Allegro  will  do	 color
       conversions  on the fly,	which will be rather slow. For optimal perfor-
       mance you should	set the	color depth to the color depth you want	to use
       before loading any fonts.

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