Do It Yourself operation

The "pattern" just offers the data pointers (see Image data pointers) to the functor.

Instantiations of the pattern are invoked via

• HxImageRep::diyOp

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

• DstImgSigT is the signature type of the destination image
• SrcImgSigT is the signature type of the source image
• DiyT is the type of the DIY functor

The requirements on the DiyT template parameter expressed as class definition are:

template<class DstDataPtrT, class SrcDataPtrT>
class DiyT
{
public:
                        DiyT(HxTagList&);

    void                doIt(DstDataPtrT dstPtr, SrcDataPtrT srcPtr,
                             HxSizes dstSize, HxSizes srcSize);

    static HxString     className();
};

Example(s):

• instantiation : HxInstDiyTranspose_c, usage : HxTranspose

For further reference :

• Method frame : HxMfDiy
• HxImageData member : HxImageData::diyOp
