Object Storage Service:Rotate

Rotate public-read or public-read-write images

For images with public-read or public-read-write ACL, append the x-oss-process query parameter to the image URL.

The following examples use this source image:

https://oss-console-img-demo-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/example.jpg

Rotate 90° clockwise

https://oss-console-img-demo-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/example.jpg?x-oss-process=image/rotate,90

Rotate 70° clockwise

https://oss-console-img-demo-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/example.jpg?x-oss-process=image/rotate,70

Rotate private images

For private images, use the OSS SDKs or RESTful API to sign the request and apply the rotation.
