Question

i am getting this error and i dont know why or understand the reason:

    vector<double> fourier_descriptor(Gdiplus::Bitmap myBitmap)
{


    vector<double> res;
    Contour c;
    vector<Pixel> frame;// = c.GetContour(p);

frame = c.GetContour(myBitmap);


    return res;

}

the error is in this line
frame = c.GetContour(myBitmap);

Answer 1

I can’t find a reference for the GetContour method, but that looks like you’re trying to pass a Bitmap by value, which (if I remember my C++ correctly) will invoke the copy constructor — and Bitmap doesn’t have a public copy constructor.

If you own Contour, rewrite that function to take a Bitmap* or Bitmap& instead (i.e. pass a pointer or reference), thereby avoiding the copy constructor.
