Overview |
Refer to Implementing Annotations. |
Remarks
Gets and sets the length of the tic mark of the specified annotation object, if hObject specifies an ANNOBJECT_RULER or an ANNOBJECT_POLYRULER object. The tic marks are the perpendicular lines that measure the units.
The length of the tic mark 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, this property is updated with the length of the longest tic mark.
You must set the AnnFlags property before setting this property. Possible values for the Flags property for this property are:
0
ANNFLAG_SELECTED
ANNFLAG_NOTTHIS
ANNFLAG_RECURSE
ANNFLAG_NOTCONTAINER
ANNFLAG_NOINVALIDATE
ANNFLAG_CHECKMENU
