Make Substack shows no progress bar

[Stein Rørvik]

I frequently extract smaller sections of large stacks (tens of gigabytes) using the Image - Stacks - Tools - Make Substack.

This works as it should, but there is no status or progress bar shown in the ImageJ main window.

If the stack is in memory this is usually not a problem, as it completes in not too many seconds. But if the stack was loaded as a virtual stack from a slow networked drive, the command may take tens of minutes or even hours to complete. It is then a great disadvantage to not have a progress bar, as you do not know how long to wait for it to complete. The same problem also applies to the stack command "Plot Z-Axis Profile".

This is not really a critical problem, just a suggestion for future improvement.

With the latest ImageJ daily build (1.51h11), the Image>Stacks>Z-axis Profile and Image>Stacks>Tools>Make Substack commands display a progress bar if the stack has more than 400 slices or it is a virtual stack.
