In/Out pixel operation

The pattern loops (a number of times) over all pixels in the image and fetches/offers each pixel from/to a pixel functor. With the In variation of the pattern the pixel functor is asked to produce a pixel value for each position in the image. With the Out variation of the pattern the pixel functor is offered the pixel value at each position to do something with it.

Instantiations of the pattern are invoked via

• "constructors/factory"
• HxImageRep::exportOp

Instantiation is done via the HxImgFtorInOut functor, with the following template parameters:

• ImgSigT is the signature type of the image
• InOutT is the type of the in/out pixel functor

The requirements for the InOutT parameter and an example of its use are given in the sections on variations:

• Translation invariant, 1 phase pixel export operation
• Translation variant, 1 phase pixel export operation
• Translation invariant, 1 phase pixel import operation
• Translation variant, 1 phase pixel import operation
• Translation invariant, n phase pixel export operation
• Translation variant, n phase pixel export operation
• Translation invariant, n phase pixel import operation
• Translation variant, n phase pixel import operation
