I'm actually not sure how our view rotation is expressed -- but we don't save it either to .kra or to .ora yet. We also don't store the zoom settings or the mirror settings. It's a good idea, though. > - View mirroring is a concept which may not be used in all other editors. Krita supports that as well. Krita also has split-view, but limited, like I said in another mail -- and I'm thinking of removing it. We used to have an overview widget, but that wasn't implemented as a low-zoom view -- it's something we want to revive. Maybe this is a good moment to start thinking of what split view really should look like for Krita :-). > > > Both of these affect the notion of what a view of the document is, but > the split-screen implementation on my branch is somewhat funky too: > > - It's structured as a binary tree dividing space, which is horrible > for other programs which might want to do this as multiple windows but > fast to dump and recreate in terms of two-panel HPaneds and VPaneds. > Leaf nodes are the views themselves.

Going with the dividers is a bit implementation specific, I think. -- Boudewijn Rempt http://www.valdyas.org, http://www.krita.org, http://www.boudewijnrempt.nl _______________________________________________ CREATE mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/create
