<p class="Body"> If the <a href="../PreProcessor/Defines.htm"><b>use_xyz</b></a> pre-processor directive is enabled, then the IntPoint class will have an extra 'Z' member and the Clipper class's <a href="../Classes/Clipper/Properties/ZFillFunction.htm">ZFillFunction</a> property will be exposed so it can be assigned a custom callback function.<br><br> This custom callback procedure requires five IntPoint parameters: the first 2 parameters are the vertices that define one line segment involved in the intersection and the next two parameters the other line segment. <em>(Since the Clipper library has been developed in an environment that uses an inverted Y axis display, e1bot and e2bot will always have Y values greater than or equal to their corresponding e1top and e2top Y values.)</em> The last IntPoint parameter contain the actual coordinates at the intersection. This last parameter is passed by reference so that its Z member can be assigned with a custom value.<br><br> </p>
