Creates an image splicing task. You can call this operation to splice multiple images into one based on a given rule and save the final image into an Object Storage Service (OSS) bucket.
Operation description
- Before you call this operation, make sure that you are familiar with the billing of Intelligent Media Management (IMM).****
- Make sure that the specified project exists in the current region. For more information, see Project management.
- You can call this operation to merge up to 10 images. Each side of an image cannot exceed 32,876 pixels, and the total number of pixels of the image cannot exceed 1 billion.
- This operation is an asynchronous operation. After a task is executed, the task information is retained only for seven days and cannot be retrieved when the retention period elapses. You can call the GetTask or ListTasks operation to query information about the task.`` If you specify Notification , you can obtain information about the task based on notifications.
