Re: [libcvd-members] Windows issues

[Simon Taylor]

The exception just means the file couldn't be opened. You can get a bit 
more information:

try
{
  Image<double> in = img_load("frog.bmp");
}
catch(CVD::Exceptions::Image_IO::OpenError ex)
{
  cout << "Open Error: " << ex.what << endl;
}

The common cause of that one is just the file path being incorrect.

I wonder why you're opening a bmp as an Image of doubles? I wasn't aware 
that bmp could support any kind of high definition formats - Image<byte> 
is generally what you want for 8-bit greyscale, or Image<Rgb<byte> > for 
24-bit RGB.

Hope that helps
