Hi all, I am currently trying to write a compressed jpeg image without any success. Here is my code: #include <string> #include <boost/mpl/vector.hpp> #include <boost/gil/gil_all.hpp> #include <boost/gil/extension/io_new/tiff_read.hpp> #include <boost/gil/extension/io_new/tiff_write.hpp> #include <boost/gil/extension/io_new/jpeg_read.hpp> #include <boost/gil/extension/io_new/jpeg_write.hpp> using namespace std; using namespace boost; using namespace gil; int main(int argc, char** argv) { string base_image_path(argv[1]); string output_image_path(argv[2]); string output_compressed_image_path(argv[3]); typedef mpl::vector< rgb8_image_t, rgb16_image_t > rgb_image_types; typedef any_image<rgb_image_types> any_image_type; typedef any_image_type::view_t any_view_type; // Read tiff image image_read_info< tiff_tag > info = read_image_info( base_image_path , tiff_tag() ); any_image_type input_image; read_image(base_image_path.c_str(), input_image, tiff_tag()); write_view(output_image_path.c_str(), view(input_image), jpeg_tag()); image_write_info< jpeg_tag > compressed_jpeg_info; compressed_jpeg_info._quality = 30; //compressed_jpeg_info._dct_method = jpeg_dct_method::fastest; write_view(output_compressed_image_path.c_str(), view(input_image), compressed_jpeg_info); } Could you please help me ? Regards, Olivier
