Although the BitmapObject object has information about the image displayed in the image field, the ImageField object has information about the field itself, such as the size of the field. The most important attribute of the ImageField class is the DisplayPolicy attribute, which determines how the image fits into the field. For more information about the DisplayPolicy attribute, see ImageField Object (see ImageField Object).

The following illustration of an ImageField and a BitmapObject displays the relationship between the two variables associated with the image field, the BitmapObject and the ImageField. For more information about using the ImageField system class, see ImageField Object (see ImageField Object).
