Example 3

This example moves the point of origin back to its original position. Translate sets the new point of origin for all subsequent

commands. Consequently, translate commands are cumulative. Therefore, to restore the previous point of origin, you must

issue a translate command that negates whatever offset was previously applied.

translate(-2,-2)
