Perspective tool

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.

[Nota] Nota

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

You can access the Perspective tool in different ways:

  • From the image menu bar Tools/ Transform Tools Perspective,
