Export Image task - The export image operation is performed on an image service resource. The result of this operation is an image resource. This resource provides information about the exported image, such as its URL, its width and height, and extent. Apart from the usual response formats of html and json, users can also request a format called image while performing this operation. When users perform an export with the format of image, the server responds by directly streaming the image bytes to the client. With this approach you don't get any information associated with the exported image besides the actual image. Users can provide arguments to the export image operation as query parameters. These parameters include the request extent, size information, interpolation, pixel type, and so on.
