saveas doesn't wait until imcontrast is finished

I would like to save the output of imcontrast using saveas like:

imcontrast(gg)
saveas(gcf,'Result.jpg')

but "saveas" doesn't wait until imcontrast is finished, so it saves the original version of image gg. Okay, when imcontast is finished I can use saveas "by hand", but I would like to prefer to do this in this code. Is there any possibilty to do this without using for example

pause(10);

? And how can I save the parameters used in imcontrast?

Thanks a lot

h = imcontrast(gg);
waitfor(h)

Simply close the tool when you are finished, the code will then continue executing.
