Return Value
The number of points (if unsuccessful, 0 is returned)
Explanation
The GetArrayPointsNum property retrieves the number of
points used to define the selection area drawn using the Select or
the FreeSelect tools in the image-editing toolbar.
In the image-editing toolbar, the Select tool and the FreeSelect
tool can be used to select an area on an image. This selected area
is defined by a set of points. In the case of the Select tool, a
rectangular selection area is drawn so only 4 points are needed to
define that area. In the case of the FreeSelect tool, however, the
selection area can be defined by a large number of points. The
GetArrayPointsNum method can be used to retrieve the number
of points that defines the selection area. This can be useful if
you want to use the GetArrayPointsXY method to
retrieve each point's X,Y coordinates. By knowing the number of
points there are, you can define the size of the array needed to
hold the X,Y coordinate values.
