作为LEADTOOLS v19更新的一部分,新版本向Document Viewer添加了一个新的虚拟文档功能。 LEADTOOLS Document Composer界面可以轻松地从任意数量的页面以及来自多个源文档的文件中创建虚拟文档。你可以在查看该文档时进行修改,并可以使用代码添加或删除页面,也可以使用拖放来进行交互式操作。由Document Composer创建的虚拟文档可以保存在服务器上,与多个用户共享,并导出为任何格式。
从任何源文件中构建或撰写文档意味着什么?想象一下,房地产经纪人准备与客户会面,并想要准备几个房产相关的打印资料。他的计算机或云盘上收集了一些文件:PDF格式的列表、DOCX格式的列表、谷歌地图的截图,甚至是访问其他客户时的一些个人照片。房地产经纪人可以使用LEADTOOLS Document Composer从每个源文件中单击并拖动所需的页面并创建新的虚拟文档,然后将其打印出来参与会议,也可以将虚拟文档导出为新的PDF并通过电子邮件发送。
如果你想要尝试该功能,请查看Document Composer演示应用程序,或直接下载最新的LEADTOOLS安装程序!
