Name

get_line_approxT_get_line_approxGetLineApproxGetLineApproxget_line_approx — Get the current approximation error for contour display.

Warning

Signature

get_line_approx( : : WindowHandle : Approximation)

Description

get_line_approxget_line_approxGetLineApproxGetLineApproxget_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_regionDispRegionDispRegiondisp_region. 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_styleSetLineStyleSetLineStyleset_line_style.

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

Result

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