 gipfel allows to save the image paramters in the comment section of

+Hidden Object Detection
+=======================
+
+gipfel tries to identify objects in its database, that are hidden by others.
+This is done by assuming that every object/peak has the form of a cone 
+with a fixed steapness. If such imaginary cone would hide the view to a
+point in the database, gipfel marks it as hidden. Hidden objects are
+not shown by default, but you can enable the display of hidden objects using
+the Option->Show Hidden menu entry. Hidden objects and hidden GPS way points
+are displayed in blue.
