Canvas reference: The restore function
The restore function complements the save function and is used to restore the state of the canvas to that which you have previously saved
The restore function restores settings previously saved by the save function. It's commonly used to eliminate any clipped region that has been set. The list of settings that are restored can be found on the save page.
An example of the restore function can be be found in the page explaining the clip function .
For an example of the save/restore functions see the save function page .
