About progress bar and Photoshop
I have been reading a lot about how to make a progress bar in photoshop (scripting) and my conclusion is that it is not worthy. The only way to make a progress bar is by using Palette window but Photoshop does not support it. If we use a dialog window, since it is modal, it will freeze whatever your script is doing so, you cannot use it (how to track the progress of a script if the script is paused while the dialog is being shown?). Although Photoshop does not support Palette, there are two workarounds that would make it work and they are using either app.refresh() or waitForRedraw() (and undocumented function that seems to me to do exactly the same thing that app.refresh() does). But as the manual says, app.refresh() will slow down considerably your code. According to my experimentation, each time you call app-refresh(), your script will waste about 1 second (no matter how powerful your computer is). That is a lot of time! In practical terms, you would use app.refresh() only a few times so your progress bar could be refreshed only a few times during the whole duration of your script, still one second lost for each time you use it. In other words, there is no good way of making a progress bar in photoshop scripting.
My question is: am I right? Is there a way to code a progress bar in PS that would not delay the code unreasonably?
