draw_sprite(3alleg4)						  Allegro manual					      draw_sprite(3alleg4)

NAME
       draw_sprite - Draws a copy of the sprite onto the destination bitmap. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void draw_sprite(BITMAP *bmp, BITMAP *sprite, int x, int y);

DESCRIPTION
       Draws a copy of the sprite bitmap onto the destination bitmap at the specified position. This is almost the same as blit(sprite, bmp, 0, 0,
       x, y, sprite->w, sprite->h), but it uses a masked drawing mode where transparent pixels are skipped, so	the  background  image	will  show
       through the masked parts of the sprite. Transparent pixels are marked by a zero in 256-color modes or bright pink for truecolor data (maxi-
       mum red and blue, zero green). Example:

	  BITMAP *spaceship;
	  ...
	  draw_sprite(screen, spaceship, x, y);

       If the GFX_HW_VRAM_BLIT_MASKED bit in the gfx_capabilities flag is set, the current driver supports  hardware  accelerated  sprite  drawing
       when  the  source  image is a video memory bitmap or a sub-bitmap of the screen. This is extremely fast, so when this flag is set it may be
       worth storing some of your more frequently used sprites in an offscreen portion of the video memory.

       Warning: if the hardware acceleration flag is not set, draw_sprite() will not work correctly when used with a sprite  image  in	system	or
       video memory so the latter must be a memory bitmap.

       Although  generally  not  supporting  graphics  of mixed color depths, as a special case this function can be used to draw 256-color source
       images onto truecolor destination bitmaps, so you can use palette effects on specific sprites within a truecolor program.
