disp_cross🔗
Short description🔗
disp_cross — Displays crosses in a window.
Signature🔗
disp_cross( window WindowHandle, coordinates.y Row, coordinates.x Column, number Size, angle.rad Angle )
Description🔗
disp_cross displays one or several crosses in the output
window. A cross is described by the coordinates of the center point
(Row,Column), the length of its bars Size and the
orientation Angle.
The operators used to control the display of regions
(e.g., set_color, set_gray, set_draw,
set_line_width) can also be used with crosses. Several crosses can
be displayed with one call by using tuple parameters. For the use of colors
with several crosses, see set_color.
