Provides a similar functionality as the XCLIP command in CAD applications. .. important:: This class handles only 2D clipping paths. The visibility of the clipping path can be set individually for each block reference, but the HEADER variable $XCLIPFRAME ultimately determines whether the clipping path is displayed or plotted by the application: === =============== === 0 not displayed not plotted 1 displayed not plotted 2 displayed plotted === =============== === The default setting is 2. ct|ts!tjdt |||_t ||_y)NzINSERT entity required, got ) isinstancer r DXFTypeErrorstr_insertr_spatial_filter)r&inserts r(__init__zXClip.__init__Zs=&&)$$'CCK=%QR R 1&9r)c|jS)zReturns the underlaying SPATIAL_FILTER entity if the INSERT entity has a clipping path and returns ``None`` otherwise. r<r+s r(rzXClip.get_spatial_filter`s###r)cd}|jj0|jjjjdd}|S)Nz $XCLIPFRAME)r;docheaderget)r&policys r(get_xclip_frame_policyzXClip.get_xclip_frame_policyfs> <<   '\\%%,,00BF r)c|jduS)z1Returns if the INSERT entity has a clipping path.Nr@r+s r(has_clipping_pathzXClip.has_clipping_pathls##4//r)ct|jtr)t|jjj Sy)z8Returns ``True`` if block reference clipping is enabled.F)r8r<r r"dxfis_clipping_enabledr+s r(rLzXClip.is_clipping_enabledqs4 d**M :,,00DDE Er)c\t|j}|y|jtS)z.Returns ``True`` if clipping path is inverted.F)get_roundtrip_xrecordr< has_sectionr)r&xrecs r(r#zXClip.is_inverted_clipxs.%T%9%9: < ;<> !  6 6:: !5!5!G!G H  x=A !(+H$XF $T%9%9: d, -*@11+M '3I913M /.2M *r)ct}t|jts t ||S|j }|j j}tj|j|j}t|dk(rt|j}t ||j}|jrtj|j|j}t|dk(rt|j}||_tj|j|j |_|S)zReturns the clipping path in WCS coordinates (relative to the WCS origin) as 2D path projected onto the xy-plane. rBrY)r3r8r<r rrbr;matrix44rr[rr]r rect_verticesr#r r!)r&rblock_clipping_pathr`wcs_clipping_pathr s r(get_wcs_clipping_pathzXClip.get_wcs_clipping_paths'$)7$.. >(3 3"::< LL ! ! #::a223F3O3OPQ x=A $X.<<>H( ':'K'K   / / JJ$$%8%F%FGM=!Q& -m < J J L .;  +6:jj$$%8%N%NO7  3! r)c|jt|j|_|j}|j|t ddd|j _t|j _d|j _ d|j _ d|j _ d|j _ t}|j||j||j!y)aSet clipping path in block coordinates (relative to block origin).
