NAME

       masked_stretch_blit  -  Scales  a  rectangular  area  skipping  pixels  with the mask color. Allegro game
       programming library.

SYNOPSIS

       #include <allegro.h>

       void masked_stretch_blit(BITMAP *source, BITMAP *dest, int source_x, source_y,  source_w,  source_h,  int
       dest_x, dest_y, dest_w, dest_h);

DESCRIPTION

       Like masked_blit(), except it can scale images (so the source and destination rectangles don't need to be
       the same size). This routine doesn't do  as  much  safety  checking  as  the  regular  masked_blit():  in
       particular you must take care not to copy from areas outside the source bitmap. Moreover, the source must
       be a memory bitmap. Example:

          BITMAP *hud_overlay;
          ...
          /* Stretch hud overlay over the screen. */
          masked_stretch_blit(hud_overlay, screen, 0, 0,
                              hud_overlay->w, hud_overlay->h,
                              0, 0, SCREEN_W, SCREEN_H);
