Graph Unit
Draws a line from the point (X1, Y1) to (X2, Y2).
Declaration:
procedure Line(X1, Y1, X2, Y2: Longint);
procedure Line(X1, Y1, X2, Y2: Longint; Color: DWORD);
Remarks:
Draws a line in the style defined by
SetLineStyle and uses the color set
by SetColor. Use
SetWriteMode to determine whether
the line is copied or XOR'd to the screen.
Note that
MoveTo(100, 100);
LineTo(200, 200);
is equivalent to
Line(100, 100, 200, 200);
MoveTo(200, 200);
Use LineTo when the current pointer (CP)
is at one endpoint of the line. If you want the CP updated automatically
when the line is drawn, use
LineRel to draw a line relative the
current pointer (CP). Line doesn't update the CP.
