The background of an oneline diagram can display a variety of objects, including lines, filled polygons, and even pictures. The latter will be discussed in this section.
Edit Mode
Simulator can insert bitmaps, jpegs, enhanced and standard metafiles, and icons from files into the oneline diagram. These pictures may either serve as a background or appear above other objects on the oneline.
To add a picture object to the oneline diagram, go to the Draw ribbon tab and select Background > Picture from the Individual Insert ribbon group. Then, click the oneline diagram at the point where you would like the top left corner of the graphic to be placed. The Open Picture Dialog will open, asking you to select the graphic file that you want to insert. When you select a file from the dialog, the dialog displays a preview image so that you can be sure that you are selecting the right file. When you have identified the file to insert, click OK. The image will then appear on the oneline. It may be resized by dragging its resizing handles.
By default, pictures are inserted at the middle stack level. Thus, they hide most other oneline display objects. To change the stack level of the picture, click it to select it, and then select the Levels/Layers button 
found in the Formatting ribbon group of the Draw ribbon tab. From the Levels/Layers Tab, select the stack level of your choice. The Base stack level places the picture below all other oneline display objects, while the Top stack level will cause the picture to obscure all other display objects.
To resize or reshape an existing picture object, click on it to select it and then drag its resizing handles.
