LiveCode isn't naturally a graphics powerhouse and its way of handling image data (often referred to as "bitmap data" by other tools) is somewhat unusual.

Handling a final image is quite flexible, but in order to create something along the lines of a jigsaw puzzle, we need to understand the format of imageData, a LiveCode property.
In this chapter, we will:
- Examine the way LiveCode stores bitmap data in an image object

- Make a collision detection map
- Create a jigsaw puzzle app that takes...
