Comments
The line width of an object is relative to its container object, and the value is interpreted using the container's scaling factors. As a result, when zooming in the line width increases, and when zooming out the line width decreases. This is the default behavior.
In some cases it might be preferable to have the line width of an annotation object remain constant, regardless of the amount of scaling (zooming). To do this, call L_AnnSetLineFixedWidth function with the bLineFixedWidth parameter set to TRUE.
