Description

disp_linedisp_lineDispLineDispLineDispLinedisp_line displays one or several lines in the output window. A line is described by the coordinates of the start (Row1Row1Row1Row1row1row_1,Column1Column1Column1Column1column1column_1) and the coordinates of the end (Row2Row2Row2Row2row2row_2,Column2Column2Column2Column2column2column_2). The operators used to control the display of regions (e.g., set_colorset_colorSetColorSetColorSetColorset_color, set_grayset_graySetGraySetGraySetGrayset_gray, set_drawset_drawSetDrawSetDrawSetDrawset_draw, set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidthset_line_width) can also be used with lines. Several lines can be displayed with one call by using tuple parameters. For the use of colors with several lines, see set_colorset_colorSetColorSetColorSetColorset_color.

Attention

The starting points and the ending points of the lines must be in the window.
