BITMAP structures hold information about any type of image loaded by
Allegro into memory (or video RAM).
BMP, TGA and PCX are loaded as bitmaps with the function load_bitmap().
get_rle_sprite will convert that bitmap into a RLE sprite so they use less
memory in RAM (most of the time).
so your code would look like this:

PALETTE mypal;
BITMAP *mybitmap = load_bitmap("file.pcx", mypal);
RLE_SPRITE *myrle = get_rle_sprite(mybitmap);

Hope this helps clarify everything.
