WinLineExt

Declaration: void WinLineExt (WINDOW * w , const WIN_RECT * Line )
Category(ies): Windows
Description: Draw a line in a window using a WIN_RECT to define the end-points. The
line is drawn in the current attribute (set with WinAttr). This routine is
similar to WinLine except that it is more accurate in terms of clipping and
the exact pixels drawn, at the expense of being much slower. Use it when
precise pixel placement is needed especially when clipping is involved (see
example).
w
Inputs:
Line — Endpoints of line to draw.
Outputs: None
Assumptions: The valid line attributes are: A_NORMAL (set), A_REVERSE (clear), and
A_XOR.
Side Effects: Slower than WinLine, but more precise.
Availability: On AMS 2.00 and higher.
