- 載入 AForge.NET 參考
- 實作 openFileDialog 讀圖
- 實作 saveFileDialog 存圖
- 開啟檔案「手動」瀏灠器載入圖。
- 以絕對路徑「自動」載入圖。
- 將圖放至專案/bin/Debug 目錄內「自動」載入圖。
Step1.
檔案 → 新增專案 → Windows Form 應用程式 → 拉物件 Form1.cs[設計] → 撰寫 Form1.cs
Step2.
方案總管 → 參考 → 右鍵加入參考 → 瀏灠(預設路徑) C:\Program Files (x86)\AForge.NET\Framework\Release → 加入參考
- AForge.Imaging.dll
- AForge.Imaging.Formats.dll
Step3.
拉入 Windows Form:
- pictureBox × 1
- button × 4
- openFileDialog × 1
- saveFileDialog × 1
Step4. Coding
