About the Perspective Tool

The Perspective tool lets you deform a drawing selection and alter its perspective. You can use the corner and edge anchor points to warp the shape.

NOTE: If you use the Contour Editor, Perspective or Envelope tool on a textured brush stroke, it will deform its texture to fit the new shape of the brush stroke. Note that this will resample the texture, which is liable to make it lose quality.
NOTE: To learn more about the Perspective tool options, see Perspective Tool Properties.
