增加 gil 读取图像错误

Boost gil read image errors

本文关键字：错误 图像 读取 gil 增加      更新时间：2023-10-16

我想编写简单的程序来读取和编辑带有boost：：gil的图像。读取图像功能始终发生错误。我继续在提升网站上找到的教程。

#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，不知道出了什么问题。似乎将不受支持的图像类型传递到图像模板中，但它显示无论参数如何 - 我也尝试传递一种类型。

我自己也刚开始编写CMakeLists.txt所以我包含了这些文件。主文件夹中的 CMakeList ：

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 在 src 文件夹中：

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会给出其他错误...

编辑：

已安装的libjpeg，CMakeLists在src dir中：

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仍然有问题，但是包含扩展名/io中的所有三个文件:(

不起作用

你缺少包括

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

然后它编译并链接：

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

@sehe提供的答案对于 Boost1.67或更早版本中发布的 GIL 是完全正确的。

由于I/O 扩展已在Boost1.68 中发布的 Boost.GIL中完全重写，因此您的示例需要调整。这里更新了，最小版本：

#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());
}

可能还值得注意的是，最新的 Boost.GIL现在需要一个符合 C++11 的编译器。

更新：Boost 1.72 提供从 Boost.MPL 移植到 Boost.MP11 的 GIL，请参阅发行说明，因此应使用mp_list而不是mpl::vector。
