This structure defines the orientation of an image. It works on the image representation and thus allows you to flip and rotate an image without modification of its data (pixels).

It is useful to manipulate the orientation of scanned black-and-white images. Since ImageGear for .NET stores such images using lossless compression, this may avoid significant expansion of memory usage while operating on these images.

Some file formats support orientation natively and this allows you to save flipped or rotated images without loss of pixel data or file size enlargement when using compression.
