Expand Image
The Expand Image command enlarges the image by extending the image border to a larger area. The result is the original image data Imbedded in a background of uniform intensity. This command is usually used before Imbedding images into the background.
The Expand Image command opens from the
Image Window > Process >
Geometry menu and 
button
on the Main Toolbar. The "immediate"
form, shown first, opens when an image or image set is displayed in
the top-most window. The general form can be used to select source
images from folders, windows, or by matching templates.
