=== Cropping an image ===

==== Cropping an image ====

You learnt how to crop an image (reduce the image to a part that you want) using Screenshot. However, in this method, you can only grab an area that is in the shape of a rectangle. Using GIMP you can crop an image in the shape of a rectangle, but you can also use a free hand selection.

Select Tools → Selection Tools → Free Select

Select <u>Tools → Selection Tools → Free Select</u>

You can move your cursor on the image to outline the area you want to crop, this is free hand, not necessarily in the form of a rectangle. Then crop the image to your selection through Image → Crop to Selection. You can export this cropped image using File → Export as and export to an image format like .png or .jpeg.
