Description

get_line_approxget_line_approxGetLineApproxget_line_approxGetLineApproxGetLineApprox returns a parameter that controls the approximation error for region contour display in the window. It is used by the operator disp_regiondisp_regionDispRegiondisp_regionDispRegionDispRegion. 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_styleSetLineStyleset_line_styleSetLineStyleSetLineStyle.
