Direct Known Subclasses:

ImageTrapModeWithThreshold

class 
Generic:ImageTrapMode

This is a generic image trap mode formula.

It takes a sequence of complex point pairs (untransformed and transformed), including image point pairs, and distances and produces a final result. It similar to generic trap mode in common.ulb.
