描述

set_drawset_drawSetDrawSetDrawSetDrawset_draw defines the region fill mode. If ModeModeModeModemodemode is set to 'fill', output regions are filled, if set to 'margin', only contours are displayed. Setting ModeModeModeModemodemode only affects the valid window. It is used by operators with region output like disp_regiondisp_regionDispRegionDispRegionDispRegiondisp_region, disp_circledisp_circleDispCircleDispCircleDispCircledisp_circle, disp_rectangle1disp_rectangle1DispRectangle1DispRectangle1DispRectangle1disp_rectangle1, disp_rectangle2disp_rectangle2DispRectangle2DispRectangle2DispRectangle2disp_rectangle2, disp_arrowdisp_arrowDispArrowDispArrowDispArrowdisp_arrow etc. It is also used by operators with gray value output for some gray value output modes. If the mode is 'margin', the contour can be affected with set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidthset_line_width and set_line_styleset_line_styleSetLineStyleSetLineStyleSetLineStyleset_line_style。

注意

If the output mode is 'margin' and the line width is more than one, objects may not be displayed.
