virtual L_INT LAnnAutomation::SetLineWidth(dLineWidth, uFlags=0)
Sets the unscaled line width of the annotation object.
The unscaled line width of an object, relative to its container object. The width is interpreted using the container's scaling factors, which are described in Low-Level Coordinate System for Annotations.
Reserved for future versions, use 0.

The line width of an object is relative to its container object, and the value is interpreted using the container's scaling factors. For example, suppose you want the line to be three pixels wide on your screen using the current scaling factors. You would use the following calculation, where A is the desired width of three pixels, B is the value that you get from the LAnnotation::GetScalarX function, and C is the value that you get from the LAnnotation::GetScalarY function:
dLineWidth = A / sqrt( B * C )
For more information, refer to Low-Level Coordinate System for Annotations.
Win32, x64.
For an example, refer to LAnnAutomation::GetLineWidth.
