The map image event is identical to the map view event with the addition of generating an image file to send along with the map view. This event was added to support work flows between the TIBCO Spotfire application and ArcGIS.
Clicking on the send map image button creates a snapshot of the current ArcMap view and writes it to a JPEG image file. The image contains everything that is visible on the map, including any selection highlighting. The path to the file is sent along with a map view event. The map view event defines the spatial locations of the corners of the image. Receiving applications use the corner locations to display the image in the correct geographic location.
The TIBCO Spotfire Extension for OpenSpirit responds to the map image event by creating a map chart and setting the image as the map chart background image.
