Operation

None

Description

The image processing features of KS3 enable you to use the pipeline to perform multiple operations on images to meet your requirements in complex scenarios. The pipeline enables you to use the vertical bar (|) to connect different operations.

Permission

To use the pipeline, you must have the GetObject permission. If the object does not exist, the following errors may be returned:

  • If you have the ListBucket permission on the bucket where the object resides, KS3 returns a 404 error.
  • If you do not have the ListBucket permission on the bucket, KS3 returns a 403 error.
