Read write and display image using openVX

Question

I am trying to read image using openVX. I have written following program by referring some samples.

#include <iostream>
#include <string>
//#include <vx_examples.h>
#include <VX/vx.h>
//#include <VX/vx_helper.h>

using namespace std;
int main(int argc, char** argv)
{
 cout << "SampleOpenVXCode" << endl;
 vx_image vxSrc;
 vx_context context = vxCreateContext();
 vxuFReadImage(context, argv[1], vxSrc);
 vxuFWriteImage(context, vxSrc, "/home/deepak/Desktop/test.jpg");
}

But I am getting following error.

openvxTest.cpp: In function ‘int main(int, char**)’:
openvxTest.cpp:18:39: error: ‘vxuFReadImage’ was not declared in this scope
  vxuFReadImage(context, argv[1], vxSrc);
                                       ^
openvxTest.cpp:20:65: error: ‘vxuFWriteImage’ was not declared in this scope
  vxuFWriteImage(context, vxSrc, "/home/deepak/Desktop/test.jpg");

Also I was not able to find the functions vxuFWriteImage() and vxuFReadImage() in the openVX headers (openvx/include/VX/vx_* ).

Can anybody help me to read write and display images using openVX.

Thank you.

There is no such function in OpenVX specification. This is being cross compiled for a specific platform? Because they might have written this API and hence appropriate header file and library needs to be linked.
