Possible values: 'auto': fill the position rectangle with data. 'equal': same as aspect=1, i.e. same scaling for x and y. WitrynaWhen resizing an image: It is important to keep in mind the original aspect ratio of the image (i.e. width by height), if you want to maintain the same in the resized image too. Reducing the size of an image will require resampling of the pixels. Increasing the size of an image requires reconstruction of the image.
