I suspect, you are missing some headers.
Hi Mateusz, Thanks. So your example worked. I had a lot of headers so started there. I finally commented just about every thing I had and still had the issue. Even with VS2017.
I should have started by just looking at your example write to file line for a subtle difference.. Here is what it was...
bg::write_view( path_to, const_view( destImg), bg::jpeg_tag() );
^^^^^^^^ need to use const_view!
Dan, Hmm, it should compile with gil::view as well. I have just checked the resize.cpp modified with VS2017 bg::rgb8_image_t square100x100(100, 100); bg::resize_view(bg::view(img), bg::view(square100x100), bg::bilinear_sampler{}); bg::write_view("out-resize.jpg", bg::view(square100x100), bg::jpeg_tag{}); It compiles. If you still encoutner the problem, I suggest you to open a new issue at https://github.com/boostorg/gil and include minimal example to reproduce the problem Best regards, -- Mateusz Loskot, http://mateusz.loskot.net
