Display RGB operation for 2D images

The pattern loops over all pixels in the image and converts the pixel value to an integer in ARGB formats for display purposes. The result is written to the given integer buffer.

Instantiations of the pattern are invoked via

• HxImageRep::getRgbPixels2d(int*,HxString,int,int,HxGeoIntType)

Instantiation is done via the HxImgFtorRgb2d functor, with the following template parameters:

• ImgSigT is the signature type of the image
• RgbT is the type of the rgb pixel functor

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

template<class ValT, class ValDoubleT>
class RgbT
{
public:
                        RgbT(HxTagList& tags);

    int                 doIt(const ValT& pixV);

    int                 doItDouble(const ValDoubleT& pixV);

    static HxString     className();
};

Depending on the display parameters set by the GUI the function doIt will be called with 1 parameter of type ImgSigT::ArithType or the doItDouble function will be called with 1 parameter of type ImgSigT::ArithTypeDouble.

Example(s):

• instantiation : HxInstRgb2dDirect_c, usage :
