API | Description |
COS supports processing images upon upload. You can also process images that are already stored in COS and save the processed images to COS. |
Pic-Operations
option to the request header and set the relevant parameters. You can also save the input images and processing results to COS. Currently, images smaller than 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)
