IGSettings is the diagnostics application which allows you to control what ImageGlue does and the way in which it does it. When you launch the application you will see something like the following.

The Last Image tab allows you to see exactly what ImageGlue is doing at any point in time. The Canvas Log and Operation Log show statistics collected on each canvas created and each operation performed. The other tabs allow you to fine tune ImageGlue and adjust the statistics collected.
