提升gil读取图像错误

时间:2018-07-02 18:16:26

标签: c++ image boost cmake boost-gil

我想编写一个简单的程序以使用boost :: gil读取和编辑图像。读取图像功能总是发生错误。我会继续在Boost网站上找到教程。

#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;
}

错误很长,不知道出什么问题了。似乎将不支持的图像类型传递到图像模板中,但是无论参数如何,它都会显示-我也尝试传递一种类型。

我也是自己编写CMakeLists.txt的新手,所以我包括了这些文件。主文件夹中的CMakeLists:

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})
src文件夹中的

CMakeLists.txt:

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})

使用read_and_convert_image会产生其他错误...

编辑:

在src目录中安装了libjpeg,CMakeLists:

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})

find_package(Boost REQUIRED COMPONENTS)
IF(BOOST_FOUND)
  target_link_libraries(edges Boost::boost)
ENDIF()
find_package(JPEG REQUIRED)
IF(JPEG_FOUND)
  include_directories(${JPEG_INCLUDE_DIR})
  target_link_libraries(edges ${JPEG_INCLUDE_DIR})
ENDIF()

cmake命令:

cmake -DJPEG_LIBRARY:PATH=/usr/lib/x86_64-linux-gnu/libjpeg.so --libdir=/usr/lib64 ..

jpeg仍然存在问题,但包括扩展名/ io的所有三个文件都不起作用:(

2 个答案:

答案 0 :(得分:1)

您缺少附件

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

然后编译并链接:

g++ -Wall -Wextra -pedantic -pthread -o sotest test.cpp -ljpeg

答案 1 :(得分:0)

@sehe提供的答案与Boost 1.67 或更早版本中发布的GIL完全正确。

由于 I / O扩展已在Boost 1.68中发布的Boost.GIL中被完全重写,因此您的示例将需要进行调整。在这里,它已更新为最低版本:

#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());
}

值得注意的是,最新的Boost.GIL 现在需要兼容C ++ 11的编译器
