Automatic rotation

Images taken by some cameras carry the orientation property. Automatic rotation is applicable to only images that carry the orientation property. After you enable the automatic rotation feature, DCDN automatically rotates these images to a proper orientation.
Notice After you enable automatic conversion to WebP, the cache hit ratio decreases. It automatically increases after a short period of time. Do not enable this feature during peak hours.

Set the action to auto-orient.

Examples
image_process=auto-orient

Manual rotation

Images can be rotated to a specific angle clockwise. Supported angles are 90°, 180°, and 270°.

Set the action to rotate.

Examples
image_process=rotate,180
