Borderline TricksDouble boundaryInside, outside or in the middle?Borders—visible or invisibleShadows(The value dimen=outer for the first circle is actually redundant, sinceby default, the parameter dimen is set to outer). Perhaps the difference willbe better seen if each figure is provided with a coordinate grid underneathas shown below:21210000 1 2 0 1 2 0 1 221Online L A T E X TutorialPart II – GraphicsPSTricksThe dimen parameter can be applied to such closed graphic objects as\psframe, \pscircle, \psellipse and \pswedge, even when doublelinesis not in effect. It then determines whether the measurements refer to theoutside, inside or the middle of the boundary. The difference however isnoticeable, only for large linewidth. The example below illustrates this.\begin{pspicture}(0,0)(5,5)\psframe[linewidth=2mm,%linecolor=Red,%dimen=outer]%(1,1)(2,2)\psframe[linewidth=2mm,%linecolor=Blue,%c○2002, 2003, The Indian T E X Users GroupThis document is generated by PDFT E X withhyperref, pstricks, pdftricks and pdfscreenpackages on an intel PC running GNU/LINUXand is released under LPPLThe Indian T E X Users GroupFloor iii, sjp Buildings, Cotton HillsTrivandrum 695014, indiahttp://www.tug.org.in£ ¡ ¢ ¤ ¥ ¦ © 9/19
