NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library. 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. SEE ALSO

NAME
load_font - Loads a font from a file. Allegro game programming library. SYNOPSIS
#include <allegro.h> FONT *load_font(const char *filename, RGB *pal, void *param); DESCRIPTION
Loads a font from a file. At present, this supports loading fonts from a GRX format .fnt file, a 8x8 or 8x16 BIOS format .fnt file, a datafile or any bitmap format that can be loaded by load_bitmap(). If the font contains palette information, then the palette is returned in the second parameter, which should be an array of 256 RGB struc- tures (a PALETTE). The pal argument may be NULL. In this case, the palette data, if present, is simply not returned. The third parameter can be used to pass specific information to a custom loader routine. Normally, you can just leave this as NULL. Note that another way of loading fonts is embedding them into a datafile and using the datafile related functions. Example: FONT *myfont; PALETTE palette; ... myfont = load_font("my_font.pcx", palette, NULL); if (!myfont) abort_on_error("Couldn't load font!"); ... textout_centre_ex(screen, myfont, "This is my own pretty font!", SCREEN_W / 2, SCREEN_H / 2, white, black); ... destroy_font(myfont); 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. SEE ALSO
