The top half of the plugin displays the amount of time taken to calculate and paint the currently displayed image.

The bottom half of the plugin displays the progress of the currently running operation, if appropriate. The amount of time elapsed so far is displayed. After that comes how far through the operation we are. Note that, as with the progress meters at the bottom of the main window, this percentage gives you the amount of the work that has been done, which may not be the same as the proportion of the time to have elapsed. Often, the speed at which the calculation can progress will vary. Finally, if possible, an estimate of the total time will be displayed. This is only an estimate, but does give an indication of how long things will take.

Finally, there is a Cancel button.
