There is limited support for including pictures on the model diagram.
To include a picture on the model diagram it must be a bitmap in gif or jpeg format. Either the whole model desktop can be used, or a submodel can be used as a placeholder. The bitmap will be cropped or tiled to fit in the available space.
The following procedure is used to add a picture to the model diagram.
The selected picture will now appear in the background of the model, or on the model desktop. You can continue to work with the submodel exactly as normal. You can resize it, in which case the picture will be cropped or tiled as necessary, or add model diagram elements, which will appear in front of the picture.
Note that the zoom commands do not affect the size of bitmaps (these are fixed in pixels). Therefore if a model diagram is zoomed in to higher magnification, the bitmap will appear smaller than before, relative to its placeholder.
