Args: other_pens: list of SegmentPens used to draw the transformed outlines. max_err: maximum approximation error in font units. For optimal results, if you know the UPEM of the font, we recommend setting this to a value equal, or close to UPEM / 1000. reverse_direction: flip the contours' direction but keep starting point. This pen does not follow the normal SegmentPen protocol. Instead, its moveTo/lineTo/qCurveTo/curveTo methods take a list of tuples that are arguments that would normally be passed to a SegmentPen, one item for each of the pens in other_pens. c~|r|Dcgc]}t|d}}||_||_d|_d|_ycc}w)NT)outputImpliedClosingLine)rpensr start_pts current_pts)r other_pensrrr:s rrzCu2QuMultiPen.__init__sO &"#EJ  s:c2|j tdy)NzmoveTo is requiredrtrUrs r_check_contour_is_openz$Cu2QuMultiPen._check_contour_is_opens    # !56 6 $rc2|j tdy)Nz closePath or endPath is requiredrwrxs r_check_contour_is_closedz&Cu2QuMultiPen._check_contour_is_closeds    ' !CD D (rc|j?t|j|jD]\}}|j|d|_yyr )rsziprrmoveTo)rrPr:s r _add_moveTozCu2QuMultiPen._add_moveTosG >> %t~~tyy9 C B !DN &rc`|j|x|_|_|jyr )r{rsrtr)rptss rr~zCu2QuMultiPen.moveTos) %%',//) rc|j|jt||jD]\}}|j|||_yr )ryrr}rrlineTort)rrrPr:s rrzCu2QuMultiPen.lineTosM ##% 3 * GB CJJO rcN|jt|ddk(r$|j|Dcgc]}|df c}y|jg}t ||j D])\}}|j ||j|df+||_ycc}w)Nrrr=) ryr rrr}rrr"r?rt)r pointsListr,rtr:s rr"zCu2QuMultiPen.qCurveTos ##% z!}  " KKJ?&&)? @   z4995 .KFC CLL& !   r } - .'@s B"cg}t|j|D]\}}|j||zt||jgt |z}g}|D]}|j|dd|j |y)Nr)r}rtr?rrr r")rrcurvesrr, quadratics quadratics r_curves_to_quadraticz"Cu2QuMultiPen._curves_to_quadratic&s"%d&6&6 "C / J MM*v- . /($,,#f+1MN  # -I   im , - j!rcF|j|j|yr )ryr)rrs rr#zCu2QuMultiPen.curveTo0s ##% !!*-rc|j|j!|jD]}|jdx|_|_yr )ryrsrr closePathrtrr:s rrzCu2QuMultiPen.closePath4sC ##% >> !yy   ,004>rc|j|j!|jD]}|jdx|_|_yr )ryrsrrr`rtrs rr`zCu2QuMultiPen.endPath;sC ##% >> !yy   ,004>rc|jt||jD]\}}|j||yr )r{r}rrrg)r glyphNametransformationstransr:s rrgzCu2QuMultiPen.addComponentBs< %%'otyy9 /JE3   Y . /rN)F)r/r0r1r2rryr{rr~rr"rr#rr`rgrmrrrorosD(  7E"   '".11/rro)rjfontTools.cu2qurrfontTools.pens.basePenrfontTools.pens.filterPenr fontTools.pens.reverseContourPenrfontTools.pens.pointPenrr r r5rormrrrsEC>.>9:8#y8#vJ=)J=Ze/e/r
