4.8. Perspektiv

The Perspective Tool is used to change the perspective of the active layer content, of a selection content or of a path. When you click on the image, according to the Preview type you have selected, a rectangular frame or a grid pops up around the selection (or around the whole layer if there is no selection), with a handle on each of the four corners. By moving these handles by click-and-drag, you can modify the perspective. At the same time, a Transformation information pops up, which lets you valid the transformation. At the center of the element, a circle lets you move the element by click-and-drag.

This tool is not actually a perspective tool, as it doesn't impose perspective rules. It is better described as a distort tool.

The information window shows a mathematical representation of the perspective transformation. You can find more information about transformation matrices on Wikipedia.

Readjust button

With this button, available since GIMP 2.10.10, you can reset the transform handles back to the original square shape, while keeping the current transformation and zoom level. This enables you to create more complex transformations by making the transformation in several steps.
