BitmapModified
If you allow the users to modify a fully-specified event-out (by settings the parameter Changeable=true), you can specify an alterative image with this parameter. This image will be displayed when an element has a control, which is not identical to its corresponding event-out in the registry. (One of the values: reference point, offset or parameter can be modified.) If no such alternative image is defined, the programs will draw a red frame around the main image (from the "Bitmap" parameter).
