我也做过类似这样的Aspose使用买单的工具，但我很好奇，如果有任何开源工具，在那里，将做到这一点。

I have done this using "pay" tools like ASPOSE, but I was curious if there are any open source tools out there that will do this.

推荐答案

我相信有可能是工具，有这样做，但如果你能得到的文件进入，然后可以很容易地光栅化的格式，它可能是值得探讨的。例如，将工作文档为PDF格式，然后缩图的。

I am sure there may be tools out there to do that, but if you can get the file into a format that can then be rasterized easily, it may be worth exploring that. eg converting the work doc to pdf then thumbnailing that.
