## 作业要求对应情况
|
||||
|
||||
- 使用 Qt 设计界面：已使用 Qt Widgets 实现菜单栏、工具栏和双栏图像显示界面。
|
||||
- 打开图片、保存图片、另存图片：已实现。
|
||||
- 缩放、平移、旋转：
|
||||
- 缩放：工具栏滑块、放大、缩小、原始大小、双击适配窗口。
|
||||
- 平移：图片位于 `QScrollArea` 中，放大后可通过滚动条平移查看。
|
||||
- 旋转：左旋 90°、右旋 90°。
|
||||
- 图片处理：灰度化、反色、目标提取、简单分类。
|
||||
- 处理前后对比：主界面左右两个 `QWidget` 区域分别显示处理前和处理后图像。
|
||||
- 显示方式：使用 Qt Widgets 显示图片，未使用 `cv::imshow`。
|
||||
- OpenCV 处理线程：灰度化、反色、目标提取、简单分类通过 Qt 线程执行，避免处理时阻塞界面。
|
||||
- Windows 应用构建发布：`.gitea/workflows/build-windows-release.yml` 会在 Gitea Actions 的 Linux Runner 中交叉构建 Windows x64 程序并上传 Release 附件。
|
||||
|
||||
## 功能
|
||||
|
||||
当前实现：
|
||||
|
||||
- 打开图片：PNG、JPG、JPEG、BMP、GIF、WebP 等 Qt 支持的格式
|
||||
- 保存当前图片
|
||||
- 保存当前处理后图片
|
||||
- 另存为 PNG / JPG / BMP 等格式
|
||||
- 图片显示：使用 Qt Widgets，不使用 OpenCV 窗口
|
||||
- 处理前 / 处理后双栏对比显示
|
||||
- 缩放：工具栏滑块、放大、缩小、原始大小
|
||||
- 平移：放大后使用滚动条移动查看区域
|
||||
- 双击图片适配窗口
|
||||
- 旋转：左旋 90°、右旋 90°
|
||||
- 翻转：水平翻转、垂直翻转
|
||||
- 简单处理：灰度化、反色
|
||||
- OpenCV 图片处理：灰度化、目标提取、简单分类
|
||||
- 其它处理：反色

```
|
||||
|

如果仓库主分支已切换到当前版本，直接构建即可；否则可手动切换：
|
||||
|
||||
```powershell
|
||||
git checkout main
|
||||
```
|
||||
|
||||
## 一键构建（推荐）
|
||||
|
||||
在 Windows PowerShell 中进入项目目录，然后执行：
|
||||
|
||||
```powershell
|
||||
powershell -ExecutionPolicy Bypass -File .\build-windows.ps1 -QtPrefix "C:\Qt\6.7.2\msvc2019_64"
|
||||
```
|
||||
|
||||
请把 `-QtPrefix` 改成你本机实际 Qt 安装目录。例如：
|
||||
|
||||
```powershell
|
||||
powershell -ExecutionPolicy Bypass -File .\build-windows.ps1 -QtPrefix "C:\Qt\6.8.0\msvc2022_64"
|
||||
```
|
||||
|
||||
脚本会完成：
|
||||
|
||||
1. 检查 Qt、CMake、编译器环境
|
||||
2. 生成 CMake 构建目录
|
||||
3. 编译 Release 版本
|
||||
4. 调用 `windeployqt` 收集 Qt 运行库
|
||||
5. 把发布文件放到 `dist-windows\chengnan`
|
||||
|
||||
构建成功后，运行：
|
||||
|
||||
```powershell
|
||||
.\dist-windows\chengnan\chengnan.exe
|
||||
```
|
||||
|
||||
## 手动构建
|
||||
|
||||
如果不使用脚本，也可以手动执行：
|
||||
在已配置 Visual Studio C++ 编译环境的 PowerShell 或 “x64 Native Tools Command Prompt for VS 2022” 中执行：
|
||||
|
||||
```powershell
|
||||
cmake -S . -B build-windows -G "Visual Studio 17 2022" -A x64 -DCMAKE_PREFIX_PATH="C:\Qt\6.7.2\msvc2019_64"
|
||||
cmake -S . -B build-windows -G "Visual Studio 17 2022" -A x64 -DCMAKE_PREFIX_PATH="C:\Qt\6.7.3\msvc2022_64;C:\opencv\build"
|
||||
cmake --build build-windows --config Release
|
||||
```
|
||||
|
||||
打包 Qt 运行库：
|
||||
|
||||
```powershell
|
||||
C:\Qt\6.7.2\msvc2019_64\bin\windeployqt.exe --release --no-translations build-windows\Release\chengnan.exe
|
||||
C:\Qt\6.7.3\msvc2022_64\bin\windeployqt.exe --release --no-translations build-windows\Release\chengnan.exe
|
||||
```
|
||||
|
||||
还需要把 OpenCV 的运行库 DLL（例如 `opencv_world4100.dll`）复制到 `chengnan.exe` 同目录。
|
||||
|
||||
## Gitea Actions / GitHub Actions 风格工作流
|
||||
|
||||
仓库中的 `.gitea/workflows/build-windows-release.yml` 使用 Linux Runner 的 Fedora 容器交叉构建 Windows x64 应用并发布 Release 附件：
|
||||
|
||||
- 安装 MinGW-w64、Qt MinGW、OpenCV MinGW 依赖
|
||||
- 使用 `x86_64-w64-mingw32-cmake` 配置 Windows 目标程序
|
||||
- 使用 Ninja 在 Linux 上交叉编译生成 `chengnan.exe`
|
||||
- 打包 `chengnan.exe`、Qt DLL、OpenCV DLL、Qt 插件目录
|
||||
- 上传 `.zip` 和 `.sha256` 到仓库 Release
|
||||
|
||||
发布上传使用仓库 Secret：`RELEASE_TOKEN`。如果没有配置该 Secret，工作流会尝试使用运行环境提供的 `GITHUB_TOKEN`。

### exe 复制到其它电脑无法运行
