# Image Alignment

By default, the Copy Region tool copies the input region of the input image to the upper-left corner of the destination image:

Most applications that copy the contents of an input region to a destination image need to define an alignment for the copy operation. By enabling alignment, you can control exactly where the tool copies the input region in the destination image, as the tool allows you to define an image coordinate that the tool will use to align both the input image and the destination image before the copy operation.

Use the Copy Region edit control or the CopyRegion class API to set alignment parameters for the input region or the destination image.
