Figure 14.151. Handle Transform tool

This tool allows you to apply moving, rotating, shearing, perspective and scaling corrections using handles placed on canvas.

Original image: a text layer

You can use 1 to 4 handles, and the effect depends on the number of handles. The tool acts on a selection, or, if there is no selection, on the whole layer. The active handle is bigger than the others. When the mouse pointer is on a handle, it goes with a small icon that represents the active action.

When you click and drag a handle, a transformation is applied, and the other handles stay at their place:

With 1 handle: click and drag the handle to move all pixels of the selection.

Figure 14.152. Example for 1 handle (Move)

With 2 handles: when you click and drag a handle, you rotate around the other handle as a center, and you scale the selection, keeping the aspect ratio.

Figure 14.153. Example for 2 handles (Rotate and scale)

With 3 handles: when you click and drag a handle, you shear and scale the selection, aspect ratio is not kept.

With 4 handles: when you click and drag a handle, you change perspective and scale the selection, aspect ratio is not kept.
