get_line_approxT_get_line_approxGetLineApproxGetLineApprox (Operator)

Name

get_line_approxT_get_line_approxGetLineApproxGetLineApprox — Get the current approximation error for contour display.

Warning

get_line_approxget_line_approxGetLineApproxGetLineApproxGetLineApprox is obsolete and is only provided for reasons of backward compatibility.

Signature

get_line_approx( : : WindowHandle : Approximation)

Description

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

Execution Information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

Parameters

Current approximation error for contour display.

Result

get_line_approxget_line_approxGetLineApproxGetLineApproxGetLineApprox returns 2 (H_MSG_TRUE) if the window is valid. Otherwise an exception is raised.
