Cage-Tool performance

Hi

First of all it is a great tool! And I love it. but I found some strange behaviour, so before I start a new bugreport, I wanted to ask you, if this is a bug or just something that's got to do with my system (Linux Xubuntu)

First: when I made a cage and want to adjust the knots, I can't. I have to create a new cage. But when I create the cage new and close it, it cuts my picture into bits. The only way to avoid this, yet, is to restart Gimp and load the motiv new. Is there another way around this?

Second: I tried out, whether I get a difference in making a cage closer to the motif or leaving a wider gap between motif and cage. Using the adjustment of filling the background with color.

Normally, the background becomes transparent, when I use the option, but when I create a cage on the edge of the motif, the background becomes filled with a part-transperent background.

I made some pictures of this:

Yes you can. Close the cage, then in tool options switch to "Create or edit mode". Then you can adjust the cage untill you switch back to transform mode.

Cage transform is only defined for the interior of the cage. It's a limitation of the algorithm. The fill works based on the pixel under your first point. It's ideal operating environment is an element on a separate layer of a larger canvas with transparent bg. Cage is somewhat special transform. It strives to be shape preserving.

Thanks Alexia
that does help :)
by the way, the examples I made were made on transparent background, I only added a white layer to make it easier to see the cage.
