# al\_reparent\_bitmap(3alleg5)

Allegro 5 API

## NAME

al\_reparent\_bitmap - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  void al_reparent_bitmap(ALLEGRO_BITMAP *bitmap, ALLEGRO_BITMAP *parent,
     int x, int y, int w, int h)
  ```

## DESCRIPTION

For a sub-bitmap, changes the parent, position and size. This is the same as destroying the bitmap and re-creating it with al\_create\_sub\_bitmap(3alleg5) - except the bitmap pointer stays the same. This has many uses, for example an animation player could return a single bitmap which can just be re-parented to different animation frames without having to re-draw the contents. Or a sprite atlas could re-arrange its sprites without having to invalidate all existing bitmaps.
