Aspose.PSD for .Net是高級PSD和入門級AI文件格式操作API，允許創(chuàng)建和編輯Photoshop文件，并提供更新圖層屬性，添加水印，執(zhí)行圖形操作或?qū)⒁环N文件格式轉(zhuǎn)換為另一種文件的功能，沒有任何Adobe Photoshop或Adobe Illustrator依賴項。

令人興奮的是，.NET版Aspose.PSD迎來了v20.8的最新更新！新增了如下三大新功能：

• 支持SoLdResource（智能對象層數(shù)據(jù)資源）
• 支持PlLdResource（智能對象層的放置層資源）
• 添加對象數(shù)組和單位數(shù)組結(jié)構(gòu)支持：ObAr / UnFl簽名
