Description

disp_ellipsedisp_ellipsedisp_ellipseDispEllipseDispEllipse displays one or several ellipses in the output window. An ellipse is described by the center (CenterRowCenterRowCenterRowCenterRowcenterRow, CenterColCenterColCenterColCenterColcenterCol), the orientation PhiPhiPhiPhiphi (in radians) and the radii of the major and the minor axis (Radius1Radius1Radius1Radius1radius1 and Radius2Radius2Radius2Radius2radius2).

The operators used to control the display of regions (e.g. set_drawset_drawset_drawSetDrawSetDraw, set_grayset_grayset_graySetGraySetGray, set_drawset_drawset_drawSetDrawSetDraw) can also be used with ellipses. Several ellipses can be displayed with one call by using tuple parameters. For the use of colors with several ellipses, see set_colorset_colorset_colorSetColorSetColor.

Attention

The center of the ellipse must be within the window.
