Повысить ошибки чтения изображений

0 голосов
/ 02 июля 2018

Я хотел написать простую программу для чтения и редактирования изображений с помощью boost :: gil. Ошибка происходит всегда с функцией чтения изображения. Я продолжаю учебники, найденные на буст-сайте. 

#include <iostream>
#include <boost/gil/gil_all.hpp>
#include <boost/gil/extension/io/jpeg_io.hpp>
#include <boost/gil/extension/dynamic_image/any_image.hpp>
#include <boost/gil/channel.hpp>
#include <boost/mpl/vector.hpp>

int main(int argc, char *argv[])
{
    namespace bg = boost::gil;
    static const std::string resources_dir = "../resources";
    static const std::string filename = "face.jpg";
    typedef boost::mpl::vector<bg::gray8_image_t, bg::gray16_image_t, bg::rgb8_image_t, bg::rgb16_image_t> my_img_types;

    bg::any_image<my_img_types> runtime_image;
    try{
    bg::jpeg_read_image(resources_dir + filename, runtime_image);
    } catch (const std::ios_base::failure &e) {
        std::cout << e.what() << std::endl;
    }

    return 0;
}

Ошибка довольно длинная, не знаю, что не так. Похоже на передачу неподдерживаемого типа изображения в шаблон изображения, но оно отображается независимо от аргументов - я также попытался передать один тип.

Я тоже новичок в написании CMakeLists.txt, поэтому я включил эти файлы. CMakeLists в главной папке: 

cmake_minimum_required(VERSION 2.8)
project(edges1)

set(CMAKE_BUILD_TYPE "Debug")
add_subdirectory(src)
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR})
set(LIBRARY_OUTPUT_PATH ${PROJECT_BINARY_DIR})

CMakeLists.txt в папке src: 

set(SOURCES main.cpp)

set(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR})
set(LIBRARY_OUTPUT_PATH ${PROJECT_BINARY_DIR})
include_directories(${CMAKE_SOURCE_DIR}/include)

find_package(Boost REQUIRED COMPONENTS)
include_directories(${BOOST_INCLUDE_DIRS})

#link_directoires(${CMAKE_SOURCE_ROOT}/lib)
#link_directoires(${LIBRARY_OUTPUT_PATH})
add_executable(edges ${SOURCES})

использование read_and_convert_image дает другую ошибку ...

EDIT:

Установленные libjpeg, CMakeLists в каталоге src: 

set(SOURCES main.cpp)

set(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR})
set(LIBRARY_OUTPUT_PATH ${PROJECT_BINARY_DIR})
include_directories(${CMAKE_SOURCE_DIR}/include)
add_executable(edges ${SOURCES})

все еще проблема с jpeg, но включение всех трех файлов с расширением / io не работает: (

Ответ, предоставленный @sehe, совершенно корректен для GIL, выпущенного в Boost 1.67 или более ранних версиях.

С тех пор, как расширения ввода / вывода были полностью переписаны в Boost.GIL, выпущенном в Boost 1,68 , ваш пример нуждается в корректировках. Вот обновленная минимальная версия: 

#include <boost/gil.hpp>
#include <boost/gil/extension/dynamic_image/any_image.hpp>
#include <boost/gil/extension/io/jpeg.hpp>
#include <boost/mpl/vector.hpp>

int main()
{
    namespace bg = boost::gil;
    using my_img_types = boost::mpl::vector<bg::gray8_image_t, bg::gray16_image_t, bg::rgb8_image_t, bg::rgb16_image_t>;
    bg::any_image<my_img_types> runtime_image;
    bg::read_image("file.jpg", runtime_image, bg::jpeg_tag());
}

Также стоит отметить, что для последней версии Boost.GIL теперь требуется компилятор, совместимый с C ++ 11 .

Вам не хватает включает 

#include <boost/gil/extension/io/dynamic_io.hpp>
#include <boost/gil/extension/io/jpeg_dynamic_io.hpp>

Затем компилирует и ссылки:
