The Create border button or the
button in the toolbar panel allow a line
to be drawn around the points with the left mouse button. The Esc key deletes
the last point. The right mouse button connects the line ends. After defining a line, the
Add Border to Map button automatically stores it in the file Border.brd and
links with the given object. The border can be deleted, stored in a file of different name
and later recovered. One can change the thickness and border color or fully hide a border.
Width or line thickness is given in pixels beginning from zero. Width 0
and 1 appear the same in the screen. When zooming, however, for example in the package
Excel, a width of 1 increases; a width of 0 does not.
