Maps can contain more than drawing objects. For example, you can add graphics.
In this lesson, you insert a raster (bitmapped) graphic and display it behind the other objects in your map.
You also modify the image in your map. Your edits do not change the original image file, but only the way the map displays it. In this lesson, you change the brightness and contrast. You also clip the image, to display only part of it.
For a tutorial on adding an FDO raster image through Data Connect, see Lesson 4, Exercise 5: Add a raster image in the Building a Map tutorial.
