Padding scales the image to a smaller size while retaining the output image’s frame size, by
filling the padded areas with black. Unlike cropping, padding does not remove any of the
source image or change the overall frame size. Instead, the image is reduced and black is
added to the borders of the frame to maintain the same frame size. The padding controls are
located in the Output Image Inset (Padding) section of the Geometry pane.

Crop, scale, and change frame dimensions
Use the Geometry pane in the Inspector window to crop, scale, and change frame dimensions
in a setting. Alternatively, you can crop the frame dimensions by dragging red frame bars in the
Preview window.
Note: In the Settings tab, geometry adjustments can be applied only to custom settings. If you
want to adjust the geometry of an Apple-supplied setting in the Settings tab, you must first
duplicate that setting and save it to the Custom folder. For more information, see
Create and
modify settings on page 35.
