Comments

The font size of an object is relative to its container object. The height of a font is interpreted using the container's vertical scaling factor. For example, suppose you want the font to appear as a 10-point font on your screen using the current scaling factor. You would use the following calculation, where A is the pixel height of a 10-point font, 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:

dFontSize = A / sqrt( B * C )

For more information, refer to Low-Level Coordinate System for Annotations.
