Hi all,
I have encountered a compilation error in Visual Studio 2010 that I can't find any information online about. The error is:
error C2338: (is_same::value)
It occurs when I call transform_pixels (..) on image views that are not grayscale. Below is example code that reproduces the error and I have attached the build output. If you comment out the first absolute difference call, the program compiles as expected. Also, if it helps, I was able to get similar code working intermittently by commenting the line and rebuilding, then un-commenting and building (not rebuilding). That made me think it may be something related to the template definitions during compile time and the previous build results effecting something.
#include "stdafx.h"
#include
#include
using namespace boost::gil;
template <typename Out>
struct op_absoluteDifference {
template <typename T> Out operator()(const T& in1, const T& in2) const {
return Out(abs(in2-in1));
}
};
template
void absoluteDifference(const SrcView1& src1, const SrcView2& src2, const DstView& dst)
{
typedef typename channel_type<DstView>::type dst_channel_t;
transform_pixels(src1, src2, dst, op_absoluteDifference());
}
int _tmain(int argc, _TCHAR* argv[])
{
rgb8_image_t img1(100,100);
fill_pixels(view(img1), rgb8_pixel_t(0,0,0));
rgb8_image_t img2(100,100);
fill_pixels(view(img2), rgb8_pixel_t(10,20,30));
rgb8_image_t img3(100,100);
fill_pixels(view(img3), rgb8_pixel_t(0,0,0));
absoluteDifference(const_view(img1), const_view(img2), view(img3)); //causes compilation error C2338: (is_same::value)
gray16_image_t img4(100,100);
fill_pixels(view(img4), gray16_pixel_t(0));
gray16_image_t img5(100,100);
fill_pixels(view(img5), gray16_pixel_t(10));
gray16_image_t img6(100,100);
fill_pixels(view(img6), gray16_pixel_t(0));
absoluteDifference(const_view(img4), const_view(img5), view(img6));
return 0;
}
I'm very new to the library so I wouldn't be surprised if I was doing something incorrectly. I appreciate any help or guidance.
Thank you for your time,
Mark
