Fx class is a base class for all image types in the FxPlug SDK. It is the parent class of both the
Fx classes which represent images stored either in RAM or on the video card, respectively.
A plug-in can query an
Fx class or subclass to get information from it such as its width and height in pixels, which field of video it represents, or what colorspace it is in. This is necessary to render most effects. For example, if your plug-in has a point parameter, it can use the input image's width and height to figure out what point in the image corresponds to the point the user has selected.
