Crop Tool Quick Tip

I had never understood how to use the Fixed aspect ratio option of the Crop tool correctly to retain the image's proportions. I learned this procedure from Beginning GIMP: From Novice to Professional, Akkana Peck, Apress, 2006.

1. Select the Crop tool and click in the image to open the Crop dialog.
2. Click on From selection to set the crop rectangle to the entire image.
3. Next check Fixed aspect ratio. Now you can drag on one of the resize handles (upper-left or lower-right) to change the size of the crop rectangle while the proportions remain the same.
4. Then you can use one of the move handles to position the crop rectangle as desired.
