question: converts coordinates from second space to first space . concode_field_sep double s_y_inv concode_elem_sep double env2[] concode_elem_sep double env1[] concode_elem_sep double s_y concode_elem_sep double s_x concode_elem_sep double s_x_inv concode_field_sep Coordinate transform concode_elem_sep Coordinate transform concode_elem_sep void setTransformation
target: Coordinate function ( Coordinate arg0 , Coordinate arg1 ) { arg1 . x = ( arg0 . x - env2 [ 0 ] ) * s_x_inv + env1 [ 0 ] ; arg1 . y = ( arg0 . y - env2 [ 2 ] ) * s_y_inv + env1 [ 2 ] ; return arg1 ; }
