The tic mark length applies only to the following annotation objects:
The dLength parameter is expressed in pixels, not in points. The length is for the whole line, not just from the intersection point with the ruler to the end point of the tic mark - it is from one end of the tic mark to the other end of the tic mark.
Note that a ruler can have tic marks of different lengths. For example, the ruler in the figure below has tic marks with several different lengths. In this case, pdLength is updated with the length of the longest tic mark.
For an example, refer to LAnnAutomation::SetTicMarkLength.
