Unary pixel operation

The pattern loops over all pixels in the image and applies the pixel functor to each pixel. The result is written to the corresponding position in the result image.

Instantiations of the pattern are invoked via

• HxImageRep::unaryPixOp
• HxImageRep::binaryPixOp(const HxValue,HxString,HxTagList&)

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

• DstImgSigT is the signature type of the destination image
• SrcImgSigT is the signature type of the source image
• UpoT is the type of the pixel functor

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

• Translation invariant unary pixel operation
• Translation variant unary pixel operation

Tags for UpoT variations:

• TransVarianceCategory : HxTagTransVar or HxTagTransInVar

• HxImageData member : HxImageData::unaryPixOp
