I don't think such a thing can be implemented without massive changes to the internals. But why would your users want such a behaviour? And what are your users?

Hmm. It probably wouldn't be incredibly difficult to modify gimp to allow opening an image with multiple views -- but it would be *very* difficult to make those views share some objects but not others.

Huh? You can have multiple views on an image since forever. There's nothing you would have to modify for this.

What is lacking if you use layers to contain this additional markup that is not to be in the report, and adjusting the visibility appropriately? I can see that it would be nice to have layer groups and read-only layers available, but I don't think that they would be essential.

P.S. please trim your quotes appropriately!

Sorry, I should have been clearer. You can of course have multiple views already, but as far as I know there is no way to make gimp automatically create multiple views when opening an image, that is, using a script or plugin. I think there is no way except to open the image and then create the new views by hand.

There is gimp-display-new(). One could easily write a little plug-in that installs itself as the load handler for a particular file extension, loads the image and creates multiple views for them. GIMP creates the first display automatically when an image is opened, but I can't think of anything that would prevent a plug-in to create more. Whether that will result in a reasonable working environment or not, I don't know. The PDB doesn't give you much control over the displays.

As I seem to have requested similar functionality, I would like to know what are these internals. Could you point me to the files which has the mentioned internals.

For example, I open an image and create a new view (View/New View menu). Then when I use the rectangle selection tool, the solid line is visible only in one view. The selection's non-solid line becomes visible in both views.

Why the tool's solid line is not visible in both views? What code file controls it?

I had one solution to the problem earlier: I suggested the tool plugins and a vector/geometry layer (perhaps different consept than what got implemented this summer). The example tool was the rectangle tool, where the tool's solid line was added to a temporary vector layer. The solid line would have been visible in both views trivially because the vector layer would had been part of the image itself.

I have a perfect solution ;-) too but I would like to check the internals first.

Because tool displays are drawn onto the view, not the image.

This is not necessarily true. The marching ants ('non-solid line') are only visible in views that have the 'Show selection' option enabled. The selection outline shows in all views of an image which are set to show it, because it is part of the image rather than the view.

Whether new views have 'show selection' enabled by default is controlled by an option in preferences. (Image windows->Appearance subsection)

Why the path or other objects would not be visible in both views?

? They are. Maybe you mean 'why should the path or other objects not be visible in both views' -- which is a question that someone else needs to answer.

I cannot answer your other questions.

What is your perfect solution?
