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

Result
get_line_approxget_line_approxGetLineApproxGetLineApproxGetLineApproxget_line_approx
returns TRUE if the window is valid.
Otherwise an exception is raised.
