def clip_end_points_contours_xld(contours: HObject, mode: str, length: Union[int, float]) -> HObject
描述
算子 clip_end_points_contours_xldclip_end_points_contours_xldClipEndPointsContoursXldClipEndPointsContoursXldClipEndPointsContoursXldclip_end_points_contours_xld clips the end
points of an XLD contour. The parameter ModeModeModeModemodemode determines
the measure used to determine which part of the contour is clipped.
If ModeModeModeModemodemode = 'length'"length""length""length""length""length", the Euclidean length of the
part to be clipped is passed in LengthLengthLengthLengthlengthlength. If ModeModeModeModemodemode
= 'num_points'"num_points""num_points""num_points""num_points""num_points", the number of points to be clipped is
passed in LengthLengthLengthLengthlengthlength。
The clipped contour is returned in ClippedContoursClippedContoursClippedContoursClippedContoursclippedContoursclipped_contours. If all
points of the input contour are clipped, no contour is returned.
Therefore, the number of returned contours is less or equal to the
number of input contours.
