In case somebody else is interested in this task, meanwhile I've
found a quite satisfying solution (no intermediate image required):
// BEGIN macro snipped
getRawStatistics( n );
getSelectionBounds( x, y, width, height );
snapshot();
setBackgroundColor( 0, 0, 0 );
run( "Clear Outside" );
// fill array with all non zero-valued pixels of the "selection bound"-area
// if these are less than n pixels, then top up with zeros
reset();
// END macro snipped
