get_line_approxget_line_approxget_line_approxGetLineApproxGetLineApprox (Operator)

Name

get_line_approxget_line_approxget_line_approxGetLineApproxGetLineApprox — Get the current approximation error for contour display.

Signature

Description

get_line_approxget_line_approxget_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_regiondisp_regionDispRegionDispRegion. 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_styleset_line_styleSetLineStyleSetLineStyle.

Parallelization

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

Parameters

Result

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

Possible Successors
