[JAI] Warp Operation
Good day, I have a question regarding the "warp" JAI operation. I've noticed that the super-class: Warp defines a method warpSparseRect that allows a period in the x and y directions to be specified.
Further, I notice that I must create an instance of one of Warp's subclasses to be used in the ParameterBlock that is passed to the create method of JAI, in order to create the operation.
My question is this: how can I specify the period values? Let's say I want to create an instance of WarpAffine, it's not immediately clear to me how I might specify the periodX and periodY values that will be used in the invocation of warpSparseRect during the operation. Of course, I might be missing the point altogether, in which case, clarification would be appreciated!
