skip command if function is unavailable?

[Guest]

Hi,

I was wondering if anyone could help.

I am trying to write a code which uses selections within it the problem is with the "smooth"command. If the image for some reason has a selection that is 100% of the image then the smooth command is unavailable which causes the script to stop working.

Does anyone know of a way to skip something if it is unavailable or any kind of workaround to it?

When you know something may fail because some condition may exist. A way to handle something like that is with a try and catch errors. You can have special code to handle specific errors or ignore them and just continue processing.

There are several selection commands that cause errrors if the entire layer is selected. If you don't want to use a try/catch block you could compare the selection bounds to the document bounds.

However a selection bounds could be equal to the a document canvas bounds and not be a problem. Bounds are rectangles selection can be any shape.
