Re: [Boost-users] GIL: New file io, almost there, but can't compile 'write_view'

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

At glance, the docs look fine.

With either: bg::write_view( path_to, destImg, bg::jpeg_tag() ); or: bg::image_write_infobg::jpeg_tag write_setttings; bg::write_view( path_to, destImg, write_setttings );

What am I missing?

I suspect, you are missing some headers. I have just updated GIL example resize.cpp to catch it up with the new GIL IO https://github.com/boostorg/gil/commit/531e671b4919420af029568e8e33ffb2baa47... I verified it compiles without errors using Visual Studio 2017 15.9.3 Preview 1.0 (FYI, I configured x64 build with Ninja using the CMake configuration provided and https://github.com/boostorg/gil/blob/develop/example/cmake/CMakeSettings.jso...) Please, git pull and git checkout develop branch, and try out the example if it compiles for you as well. I hope it does. If it does, compare your program against it to see what is different/missing. p.s. FYI, if you prefer, there is also https://lists.boost.org/mailman/listinfo.cgi/boost-gil Best regards, -- Mateusz Loskot, http://mateusz.loskot.net
