then ur must also be provided, but box cannot.longitude and latitude, for the

ll and
ur corners within the lon-lat corners specified in the image data. (A
previous version trimmed in UTM space, and in fact this may be done in future
also, if a problem in lonlat/utm conversion is resolved.) An error results if
there is no intersection between the trimming box and the image box.
