I'm using MSVC 2017 and compiled with:
cl "/IC:\Program Files\ImageMagick-7.0.6-Q16\include" bug.cc

The error is two lines:
bug.cc(6): error C2065: 'Quantum': undeclared identifier
bug.cc(6): error C2059: syntax error: 'constant'

I can reproduce this same bug in Ubuntu 17.04 with:
g++ -I/usr ...

When compiling this:

#include <iostream>
#include "Magick++.h"

int main()
{
std::cout << QuantumRange << std::endl;
}


I get:
error C2065: 'Quantum': undeclared identifier

This appears to be a namespace issue. I thought it might be in the MagickCore namespace, but that didn't work either.

The camera encoded JPEG looks slightly smaller (4368x2912) than the raw CR2 image (4386x2920).

However the CR2 to BMP image is much brighter:


than the camera JPEG:

After your "img.read", the image is not in Bayer format.

You have found that the top-left pixel of a de-bayered image is different to the top-left pixel of the in-camera JPG. Well, yes, is that surprising?


I know that the decoded raw image I'm dealing with is no longer in Bayer filter format ...

I'm trying to decode a raw CR2 image with Magick++ but am getting some strange results. I want to get the RGB color values for each pixel so I can loop through them and do some analysis.

To decode the CR2 I'm using:

Image img;
img.read("cr2:image.CR2");
Pixels view(img);
Quantum *pixels = view ...
