Cropping
By default, the straightened image is cropped to the cropping area that is displayed in the preview window. The final image has the same
aspect ratio as the original image, but it has smaller dimensions. However, you can preserve the original width and height of the image by
cropping and resampling the image.
You can also produce an image at an angle by disabling cropping and then using the Crop tool to crop the image in the drawing window.
