The only action here is to push the "Invert" button and observe the result in the lower right-hand window.
The constant used for true is 255 and for false is 0.
The output is displayed to the right of the input image.
Pressing the green start button causes the operator to run. Pressing the Stop button causes the operator to stop running. This is useful if the system being run on is very slow and the operator is taking a long time to complete.
The time box shows the amount of time which the operator took to complete the process on the input image.
You can inspect the input and result image pixel values by depressing the left mouse button and moving the cursor over the desired pixel. The pixel coordinates and gray-level value are displayed underneath the image. Note that some images are larger than the displayed 256x256 display window. Larger images are subsampled in an appropriate manner.
You can find out about known problems with the system here.
