API | Description |
Processes an image during upload, or processes an image stored in COS and saves the processing result to COS. |
Pic-Operations to the request header and set relevant parameters. You can also save the input images and processing results to COS. Currently, images within 20 MB can be processed.cos_status_t *ci_put_object_from_file(const cos_request_options_t *options,const cos_string_t *bucket,const cos_string_t *object,const cos_string_t *filename,cos_table_t *headers,cos_table_t **resp_headers,ci_operation_result_t **results)
