Image after cropping

There are many reasons to crop an image; for example, fitting an image to fill a frame, removing a portion of the background to emphasize the subject, etc. There are two methods to activate the crop tool. Click the button in the Toolbox, or use ToolsTransform ToolsCrop in the image window. This changes the cursor and allow you to click and drag a rectangular shape. The button in the toolbox is the easiest way to get to any of the tools.

Crop rectangle with a fixed aspect ratio

After completing the click and drag motion, a rectangle with special regions is shown on the canvas. As the cursor is moved over the different areas of the selected crop area, the cursor changes. You can then drag the rectangle's corners or edges to change the dimensions of the selected area. As shown in the figure above, as the crop area is resized, the dimensions and ratio are shown in the status bar. Double-click inside the rectangle or press Enter to complete cropping. See Kohta 4.4, ”Rajaa” for more information on cropping in GIMP.

If you would like to crop the image in a specific aspect ratio, such as a square, make sure the tool options are visible (WindowsDockable DialogsTool Options). In the Tool Options dockable, check the mark next to Fixed Aspect Ratio. Type the desired aspect ratio in the text field below, such as 1:1.

You also have buttons to change the aspect from landscape to portrait. After you set the aspect ratio, drag one of the corners of the crop rectangle to update it. The rectangle changes to the chosen ratio, and when you drag it should maintain that ratio.
