NAME

6       save_bitmap  -  Saves  a bitmap into any supported file format. Allegro
7       game programming library.

SYNOPSIS

10       #include <allegro.h>
11
12
13       int save_bitmap(const char *filename, BITMAP *bmp, const RGB *pal);
14

DESCRIPTION

16       Writes a bitmap into a file, using the specified palette, which  should
17       be an array of 256 RGB structures. The output format is determined from
18       the filename extension: at present this function supports BMP, PCX  and
19       TGA formats.
20
21       Two  things  to  watch out for: on some video cards it may be faster to
22       copy the screen to a memory bitmap and save the latter, and if you  use
23       this  to  dump the screen into a file you may end up with an image much
24       larger than you were expecting, because Allegro often  creates  virtual
25       screens  larger  than  the  visible  screen. You can get around this by
26       using a sub-bitmap to specify which part of the screen to save, eg:
27
28          BITMAP *bmp;
29          PALETTE pal;
30          ...
31          get_palette(pal);
32          bmp = create_sub_bitmap(screen, 0, 0, SCREEN_W, SCREEN_H);
33          save_bitmap("dump.pcx", bmp, pal);
34          destroy_bitmap(bmp);

RETURN VALUE

37       Returns non-zero on error.
