Paint Edit > Deform Layer

Warps and deforms an image by moving the four corners and sides.

Constraint Type

Free – Lets you reshape any side or corner independently.

Skew – Mirrors the change on one side or corner to the opposite side or corner.

Deform Type

Perspective – Changes the midpoint of the image as you change the control points, and changes the image so it looks like it has been tilted away.

Distort – Reshapes the image, but does not attempt to force a perspective view.

Interactive Display

Check this option to see the changes as you distort the image.

Uncheck it to speed up the action by only showing the result of the distortion when you release the mouse button.

Snap to Guidelines

If this option is checked, the sides and corners snap to the guidelines.

Guidelines are created based on the position of the point when you start to drag it. Using the guidelines can help you make changes that are controlled by the borders of the image layer.

Horizontal Bias / Vertical Bias
These sliders let you adjust the midpoint of the image horizontally or vertically.

Image Deform operations can be undone using the standard Edit > Undo menu item.

When Image Deform is selected, the options are added to the Paint panel.

All Alias snap modes (grid, point, and curve) work with image deformation, allowing the manipulator handles to be snapped to geometry.
