Using Area of Interest with Image Crop

GeoExpress is designed to accommodate a workflow that demands a number of image customizations at a single encode. Accordingly, it is possible to crop an image and encode an area of interest at the same time. A useful workflow would be to first define a crop region in an image and then define an area of interest.

To specify your area of interest in relation to an existing crop region:

1. Select Area of Interest… from the Tools menu.
2. Click Show Image for an image on which you have already defined a crop region (see The Image Crop Tool). The region you defined appears marked out in lines and labeled as the crop region.
3. Define your area of interest and encode.

You can specify an area of interest anywhere in the image, regardless of whether or not it is in the crop region. Obviously, areas of interest defined outside a crop region will not appear in the results for the cropped version of the image, but this may be a desired effect since a project can be used for multiple operations.

In the illustration below, an area of interest is being drawn within an existing crop region.
