Geometries in the first layer are clipped with geometries in the second one. &#10;&#10;Attributes are not modified, and each geometry is associated to the same set of attributes in the output layer as it was in the input one, even if the geometry itself has changed due to clipping. Attributes containin values of area, perimeter or any other ones related to the geometry shape should be recalculated.&#10;&#10;The following picture show the result of applying the difference algorithm to two layer, one with each polygon. The clipping layer is shown with transparent fill." description="Description" type="0">
