Alibaba Cloud CDN supports automatic image rotation and manual image rotation. You can rotate images to change the orientation or angle.
Note
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. You can enable automatic rotation by following instructions on Enable image processing.
Important 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.
