Detailed Description

Convert image types.

The following example available in tutorial-image-converter.cpp shows how to convert an OpenCV cv::Mat image into a vpImage:

#include <visp/vpImageIo.h>
#include <visp/vpImageConvert.h>
int main()
{
#if defined(VISP_HAVE_OPENCV) && (VISP_HAVE_OPENCV_VERSION >= 0x020100)
  try {
    cv::Mat A;
#if (VISP_HAVE_OPENCV_VERSION >= 0x030000)
    A = cv::imread("lena.bmp", cv::IMREAD_GRAYSCALE);
#else
    A = cv::imread("lena.bmp", CV_LOAD_IMAGE_GRAYSCALE);
#endif
    vpImage<unsigned char> I;
    vpImageConvert::convert(A, I);
#  ifdef VISP_HAVE_LIBPNG
    vpImageIo::write(I, "lena.png"); // Gray
#  endif
  }
  catch(vpException e) {
    std::cout << "Catch an exception: " << e << std::endl;
  }
#endif
}

Convert a vpImage<vpRGBa> to a yarp::sig::ImageOf<yarp::sig::PixelRgba>

A yarp::sig::Image is a YARP image class. See http://eris.liralab.it/yarpdoc/df/d15/classyarp_1_1sig_1_1Image.html for the YARP image class documentation.

Parameters

src	: Source image in ViSP format.
dest	: Destination image in YARP format.
copyData	: Set to true to copy all the image content. If false we only update the image pointer.
