IlvBitmapFilter is the base class of all image processing classes in Views. It defines the interface for image processing classes using a single method:

apply

This method accepts an array of IlvBitmapData and returns another IlvBitmapData.

The ilvbmpflt library from the Views foundation package defines many subclasses of IlvBitmapFilter; most of them are implementations of the W3Cs SVG filters specification. In the following sections, you will find a list of the image processing classes and their features.
