Selection Tool

This tool is used to select rectangular areas of an image, and perform deformations on selected data.

You can select an area of an image by clicking and dragging a rectangle on the image with the left mouse button. There are also other methods of creating a selection, such as using selection-draw mode or pasting image data from the clipboard.

Once you've selected something, you can rotate and scale it with the Rotate/scale mode button, or deform it with the Deform mode button. Each mode will cause the selection to have a rectangular border on it, with lines going to the center of the selection. At each junction of these lines, there will be a small "stub" that you can click and drag with your mouse. You'll know that your mouse is on top of a stub because the mouse pointer will change to an up-arrow symbol.
