Scripting, toggles and accessing the application state

Hello everybody,

I am considering moving from Photoshop to The Gimp entirely. I did bend Photoshop to my needs and I master perfectly everything I need to master with this software. I am NOT a beginner in the world of image editing.

Therefore, before starting the long and painful process of learning a new software, I need to be sure it is worth it.

Question 1) Can I add a layer mask, make it active, add some noise, blur the thing, get a selection from a previously saved alpha channel and all that sort of things through scripts. Don't tell me how, I just want to know if I can do it.

Question 2) Can I access the application state through scripts? I mean is it possible to know if a layer mask is already added to the active layer or if the layer palette is visible?

Question 3) As far as I understand it, it is not possible to have toggles at the moment. Ctrl z twice will cancel 2 actions instead of undoing and redoing the last action. Am I right?

Cordialement,

John

Ctrl + Z = Undo
Ctrl + Y = Redo
Hold down Ctrl and do a two-finger dance to toggle.

This is unfortunately not true for german kezboards...

Yes

Yes

or if the layer palette is visible?

No. Scripts have no direct control on the UI.

There are parts of the UI that are toggles (for instance, Tab to show/hide dialogs, or Ctrl-T to show/hide the selection). It is normally useful to undo several steps in most applications, and I don't remember ever using an application where Ctrl-Z is a toggle as you describe (but there s no real standard for the "redo" shortcut)

You'll find there are two languages supported out of the box to write scripts: the historical script-fu (a LISP dialect), and Python. Unless you are already well versed in LISP/Scheme, use Python.

Scripting, toggles and accessing the application state

I answer on this thread, the other one (no subject) was another mistake of my part.

So as Jan said we aren't all that fluent in typing.

My personnal reason is that I used Photoshop for 21 years now and I consider that a program should yield to its users' needs and not the other way round.

For example I need a toggle when working on an image for which I have a sketch. Sometimes I need to show the layer with the sketch, then hide it then show it then hide it to see what is on the sketch that I lost on the image I built. Pressing F8 repetitively in very rapid strokes generally do the trick. Don' forget to half close your eyes as well

To some extent...; You can't take Excel and require it behaves like Photoshop. A program also has its own "philosophy", the more you stick to it, the happier you are. As they says the hard part is not learning Gimp, it's unlearning Photoshop.

Scripting, toggles and accessing the application state

I understand the technique having used Photoshop for 27 years. I have scripted Indesign, Pagemaker, Corel draw (made it draw pie charts with callouts from a simple list of data), Word, Excel. It was fun but the time I spent debugging was better put to use using the other side of my brain and being creative.

That’s just me.

Sans souci, Rick

Another approach is to duplicate the layer you are working on and put it above the original layer. Turning the dupe layer on/off will reveal the changes.
