OK, my Zen is back. I updated develop branch. Thanks to everyone who looked into my issue. Christian On Mon, Jul 3, 2017 at 4:57 PM, Christian Henning wrote:

Hi all,

my metaprogramming zen is failing me and I like to ask for some help.

Using gil's updated develop branch the following code creates a compilation error with Visual Studio 2015 Update 3.

#include

using namespace std; using namespace boost; using namespace gil;

int main() { gray1_image_t img; write_view( "", view( img ), tiff_tag() );

return 0; }

The compiler output is here:

I think the error is in https://github.com/boostorg/gil/blob/develop/include/ boost/gil/premultiply.hpp#L29

but I'm not sure what to do.

Any help would be very helpful!

Thanks, Christian
