Controlling bitmap images with Lingo or JavaScript syntax

Lingo or JavaScript syntax lets you control bitmap images in two ways. First, you can perform
simple operations that affect the content of entire image cast members. These operations include
changing the background and foreground colors in addition to switching the image that appears
in a specific cast member with that of another cast member. Each of these operations manipulates
a property of the entire image cast member.
Second, you can use Lingo or JavaScript syntax to perform fine manipulations of the pixels of an
image or to create entirely new images. When you use script, you can be extremely flexible about
which images you display. You can create images based on dynamic information, such as user
input, or based on any other factors you want to include. To perform this kind of image
operation, Lingo or JavaScript syntax works with image objects. For more information, see
"Creating image objects" on page
