名称

disp_ellipseT_disp_ellipseDispEllipseDispEllipsedisp_ellipse — Displays ellipses.

参数签名

disp_ellipse( : : WindowHandle, CenterRow, CenterCol, Phi, Radius1, Radius2 : )

描述

disp_ellipsedisp_ellipseDispEllipseDispEllipseDispEllipsedisp_ellipse displays one or several ellipses in the output window. An ellipse is described by the center (CenterRowCenterRowCenterRowCenterRowcenterRowcenter_row, CenterColCenterColCenterColCenterColcenterColcenter_col), the orientation PhiPhiPhiPhiphiphi (in radians) and the radii of the major and the minor axis (Radius1Radius1Radius1Radius1radius1radius_1 and Radius2Radius2Radius2Radius2radius2radius_2).

The operators used to control the display of regions (e.g., set_drawset_drawSetDrawSetDrawSetDrawset_draw, set_grayset_graySetGraySetGraySetGrayset_gray, set_drawset_drawSetDrawSetDrawSetDrawset_draw) 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_colorSetColorSetColorSetColorset_color.

注意

The center of the ellipse must be within the window.
