Modify an image layer by changing the shape of an area of interest.

See Modify an object with curve warp shapes

Use this tool to quickly modify an image layer to change the appearance of an object without spending extensive time remodeling a speculative design change. Using the ability to warp a shape on an image, you can quickly answer the question, "What if it were taller/shorter/rounder/more square?"

To manipulate an image layer using Make warp shape:

Make the image layer current.
Ensure that you have a curve or curves that you want to serve as the shape manipulators.
Choose Paint Edit > Make warp shape. Click the curve or curves you want to be warp shapes.
A check mark appears next to each curve.
Click Accept to convert the curves to warp shapes.
Now that you have created warp shapes, drag CVs, scale curves, or perform other actions upon the shape. You will interactively see the image warp, based on the movement of the curve or CVs on the curve.

A new section appears in the Paint Control panel while you are warping an image.

Note the grid distortion where the roof line has been moved.
