### 4.5. Shear Tool

Shear tool is used to shift one part of an image, a layer, a selection or a path to a direction and the other part to the opposite direction. For instance, a horizontal shearing will shift the upper part to the right and the lower part to the left. A rectangle becomes a diamond. This is not a rotation: the image is distorted. To use this tool after selecting, click on the image or the selection: a grid is surperimposed and the Shearing Information dialog is opened. By dragging the mouse pointer on the image you distort the image, horizontally by default (x direction). To shear vertically press Shift and click on the grid (this operation is not well perfected). When you are satisfied, click on the Shear button in the info dialog to validate.
