Abstract: A document preview system provides previews of a native document to client devices. The previews include comments associated with native objects in the native document. The document preview system identifies bounding areas in the preview associated with the native objects, which may be identified by the rendering markers applied to the native document prior to rendering. Using the bounding areas, the document preview system identifies comments for the native document and determines the location to display the comment using native objects associated with the comment. When a new comment is received from a user for a preview of a native document, the document preview system determines native objects for the new comment that match a user's selection for placing the new comment. The new comment is inserted with the native objects in the native document.

Abstract translation: 文档预览系统将本机文档的预览提供给客户端设备。 预览包括与本机文档中的本机对象相关联的注释。 文档预览系统识别与本地对象相关联的预览中的边界区域，其可以在渲染之前由应用于本机文档的呈现标记来识别。 使用边界区域，文档预览系统识别本机文档的注释，并使用与注释关联的本机对象确定显示注释的位置。 当从用户接收到用于预览本机文档的新注释时，文档预览系统确定与用户的选择相匹配的新注释的本地对象来放置新注释。 新注释与本机文档中的本机对象一起插入。
