Description

disp_rectangle2disp_rectangle2DispRectangle2DispRectangle2DispRectangle2 draws one or several arbitrarily oriented rectangles in the output window. A rectangle is described by the center (CenterRowCenterRowCenterRowCenterRowcenterRow,CenterColCenterColCenterColCenterColcenterCol), the orientation PhiPhiPhiPhiphi (in radians) and half the lengths of the edges Length1Length1Length1Length1length1 and Length2Length2Length2Length2length2. The operators used to control the display of regions (e.g. set_drawset_drawSetDrawSetDrawSetDraw, set_grayset_graySetGraySetGraySetGray, set_drawset_drawSetDrawSetDrawSetDraw) can also be used with rectangles. Several rectangles can be displayed with one call by using tuple parameters. For the use of colors with several rectangles, see set_colorset_colorSetColorSetColorSetColor.

Attention

The center must lie within the window boundaries.
