This function will add the Active Rectangle on frame A2 to A1 and put the result in Out. On pressing return a dialog appears asking if you wish to replace A1. A2 is multiplied by factor/1000 before adding, a negative factor would subtract. Remember the range of each colour component is 0 to 255 so if you add or subtract the resultant values are limited to this range which means it is easy to loose information from a picture due to over/under saturation.
The Macro version takes one parameter.
The Menu version allows you to adjust the 'factor' with the usual keys. If you move to another frame, or change the Active Rectangle before pressing Return to terminate this function a dialog will appear asking if you wish to use the function wiith the same settings on the new frame or region. O will toggle the Active Frame and Out, thus letting you see the before and after frames. Escape will abort this tool but Out is still modified. Changes to a Frame may not be reflected in the Picture until it is redrawn e.g. by pressing Escape.
