Global Variable

kCIImageApplyOrientationProperty

The key for transforming an image according to orientation metadata.

Declaration

const CIImageOption kCIImageApplyOrientationProperty;

Discussion

Images can contain metadata that reveals the orientation at capture time. You can load this metadata into CIImage with imageWithContentsOfURL: or initWithData: when the captured image contains orientation metadata. Use any of the initWith:options: methods if the kCIImageProperties (NSDictionary of metadata properties) option is also provided.

If the value of this key is true, then calls to imageWithContentsOfURL:options: and imageWithData:options: will return the image transformed according to its orientation metadata.
