The IlvMergeFilter Class
The IlvMergeFilter class lets you composite input image layers on top of each other using the over operator.
Many effects produce a number of intermediate layers in order to create the final output image. This filter allows us to collapse them into a single image. Although this could be done by using n-1 IlvComposeFilter filters, it is more convenient to have this common operation available in this form, and offers the implementation some additional flexibility.
