Global Variable


A key for specifying whether to ignore the image orientation. The associated value is a Boolean value packaged as an NSNumber object. The default value is NO. An image is usually loaded in its proper orientation, as long as the associated metadata records its orientation. For special purposes you might want to load the image in its physical orientation. The exact meaning of "physical orientation” is dependent on the specific image.
