The Trimming properties dialog box controls the method used for trimming imported images so they are all exactly the same size. This is usually used only for images scanned from negatives, transparencies or photographic prints. You probably do not need to use this dialog box if you are using pictures from a digital camera
Use these entry fields to set the width and height of the trimmed image in pixels. When you are trimming by marking corners, The Panorama Factory computes the default trimmed size from the first set of corners you mark, but you can use these entry fields to override the computed values. If you have overridden the values, setting them to zero will cause The Panorama Factory to recompute the default size.
Use this control to change the choice of trimming method. (Note that the Trim menu and the tool bar offer two of these three choices.)
Use these entry fields to set margins on the trimming source.
Positive numbers reduce the size of the trimming region. When you use the Corners method, the edges of the trimming region typically skim along the edges of the source image. Slightly reducing the size of the trimming region eliminates the possibility of including a few pixels that are actually outside the frame.
Negative numbers enlarge the trimming region. You can use this to add a border around the trimming region.
