作为许多文档和成像工作流程的重要组成部分，LEADTOOLS Annotations SDK提供了一个界面来标记具有各种形状，注释，突出显示，标尺和修订的图像，并带有用于永久更改图像或存储信息以撤消和更改注释的选项。

LEADTOOLS注释具有足够的便携性和灵活性，可用于各种不同的图像和文档格式。LEADTOOLS SDK提供的其他注释类型包括私有DICOM数据元素，存储在TIFF标签中的Wang注释，IBM FileNet P8注释，Daeja注释以及PDF标记和注释。注释可以成为数据的永久部分，也可以作为XML，SVG和EMF导出。

下面的代码显示了创建加载，保存和拆分注释的解决方案所需的基础知识。如果您需要完整的分步教程，请查看我们的控制台C＃教程：如何加载，保存和拆分注释。
