POW Contours and Regions

POW can create contour maps of images and read/write/create standard SAO regions files.

Contours:

The image below shows a set of contours overlain on top of an image. The blue contours were made from a separate radio map image and then moved to this graph containing an optical image of the same object. The dialog box shows the options available for creating contours.

Regions:

Region shapes supported are circle, ellipse, box, polygon, point, and line. Shapes can be inclusive ('+' shapes drawn in grey) or exclusive ('-' shapes drawn in red). All shapes can be moved and reshaped with the mouse by dragging the green handles drawn on the current shape.
