So, I had to deal with a lib I worked on last a couple of years ago. Great news, the file IO has been greatly simplified in 1.68. I was able to retire several dozens of cryptic,(for me), lines. The old code won't compile as the Adobe extensions are gone. I'm almost there, I can read files, but I don't understand why I can't get the writer to compile. I get to my code, in case it matters: bg::rgb8_image_t destImg( res, x ); resize_view( view( sourceImg ), view( destImg ), bg::bilinear_sampler( ) ); and rgb8_image_t should be a good one from what I read: <https://www.boost.org/doc/libs/1_68_0/libs/gil/doc/html/io.html> With either: bg::write_view( path_to, destImg, bg::jpeg_tag() ); or: bg::image_write_info<bg::jpeg_tag> write_setttings; bg::write_view( path_to, destImg, write_setttings ); ms140 complains: 1>C:\cpp\boost_1_68_0\boost/gil/extension/toolbox/metafunctions/get_pixel_type.hpp(33): error C2039: 'reference': is not a member of 'boost::gil::image<boost::gil::rgb8_pixel_t,false,std::allocator<unsigned char>>' 1> c:\cpp\boost_1_68_0\boost\gil\typedefs.hpp(176): note: see declaration of 'boost::gil::image<boost::gil::rgb8_pixel_t,false,std::allocator<unsigned char>>' 1> console_test.cpp(248): note: see reference to class template instantiation 'boost::gil::get_pixel_type<boost::gil::rgb8_image_t>' being compiled 1>C:\cpp\boost_1_68_0\boost/gil/extension/toolbox/metafunctions/get_pixel_type.hpp(34): error C2146: syntax error: missing '>' before identifier 'reference' What am I missing? Do I need to supply more information? I'll put the whole thing in a url if needed. Thanks, Dan.
