NAME

       BITMAP - Stores the contents of a bitmap. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       typedef struct BITMAP

DESCRIPTION

          int w, h;               - size of the bitmap in pixels
          int clip;               - non-zero if clipping is turned on
          int cl, cr, ct, cb;     - clip rectangle left, right, top,
                                    and bottom
          unsigned char *line[];  - pointers to the start of each line

       There  is  some  other  stuff  in the structure as well, but it is liable to change and you shouldn't use
       anything except the above. The `w' and `h' fields can be used to obtain the size of an existing bitmap:

          bmp = load_bitmap("file.bmp", pal);
          allegro_message("Bitmap size: (%dx%d)\n", bmp->w, bmp->h);

       The clipping rectangle is inclusive on the left and top (0 allows drawing to position 0) but exclusive on
       the  right  and bottom (10 allows drawing to position 9, but not to 10). Note this is not the same format
       as that of the clipping API, which takes inclusive coordinates for all four corners.  All the  values  of
       this  structure  should  be  regarded as read-only, with the exception of the line field, whose access is
       described in depth in the "Direct access to video memory" section of the manual. If you  want  to  modify
       the clipping region, please refrain from changing this structure.  Use set_clip_rect() instead.
