影象處理控制元件Aspose.Imaging v19.6新版亮點示例詳解（1）
阿新 • • 發佈：2019-08-16
Aspose.Imaging for .NET一種高階影象處理控制元件，允許開發人員建立，編輯，繪製或轉換影象。影象匯出和轉換是API核心功能之一，它允許在不安裝Photoshop應用程式或任何其他影象編輯器的情況下儲存為AdobePhotoshop®本機格式。
近期釋出了Aspose.Imaging for .NET v19.6，JPEG輸出中不再保留IMAGINGNET-3351 DPI屬性，下面我們一起來探索新版中的新增功能及其工作原理。>>歡迎下載Aspose.Imaging for .NET v19.6體驗
