I have been working on rigging on another software meant for 2d animation and I have noticed somethings that are already made in krita but connected different so it has a different usage altogether.
The idea:
Transformation filter but with the twist that you can keyframe from the original source image making various shapes through time.
As you can see this is a well known transformation mode. The different idea in this case would it be constantly active when a transformation filter acting with the timeline.
Why use this?
Well strangely it acts strangely efficient on many situations to the points certain programs revolve all around that fact.
Why do it?
Should be fairly simple to do since the base to create the cage and the deformation is already made and would allow a traditional animator to have a really powerful tool to ease the work load from tedious tasks like real tweens for less complex shapes.
This would make the curve docker relevant and still remain on the 2d realm. I cannot stress how much you can get away with this modifier.
Deformation notes?
This kinda hinges on the fact that reverting back to the original shape will give the same results as before and that is only possible if what is drawn before this deformer is applied is set inside a mesh and this deformer acts over that mesh instead of the pixels directly that would cause loss of data.
Timeline extra notes?
I would dare to say that deforming a single object is awesome but if some how the object is able to be swapped on a given keyframe with another drawing and mesh it would prove making animation much easier in the long run.
Path interpolation?
So the mesh points would be bound to control points from the cage and they would linearly travel from key frame to key frame. Makes sense and works most of the time but can create a issue with circular motions making the cage scale the object up and down. My suggestion here would be to show the path of control points between keyframes like a bezier curve and make the control points take that path. This would make circles but perhaps curves much easier to achieve.
By products?
This would probably create an effect of animation files have less pixel information and make smaller files at least I imagine it too.
