Description

get_line_approxget_line_approxGetLineApproxGetLineApproxGetLineApproxget_line_approx returns a parameter that controls the approximation error for region contour display in the window. It is used by the operator disp_regiondisp_regionDispRegionDispRegionDispRegiondisp_region. ApproximationApproximationApproximationApproximationapproximationapproximation controls the polygon approximation for contour display ( 0 <=> no approximation). ApproximationApproximationApproximationApproximationapproximationapproximation is only important for displaying the contour of objects, especially if a line style was set with set_line_styleset_line_styleSetLineStyleSetLineStyleSetLineStyleset_line_style.
