用于处理现有PDF的Ruby库 [英] Ruby library for manipulating existing PDF

问题描述

例如，我正在搜索一个库来编辑已经存在的PDF，并在每个页面上添加一个水印.也可以每隔一页等空白.

I'm searching for a library to edit already existing PDF's and add a watermark to each page, for example. Could also be blank every other page etc.

那里似乎有一些PDF库，但是只有极少数的PDF库可以编辑现有的PDF，而我对选择哪种方法感到迷茫.

There seem to be a few PDF libraries out there, but only very few of them can edit existing PDF's and I'm a bit lost on which way to go.

有什么建议吗?

谢谢.

推荐答案

我有一个具有此功能的虾分支.不幸的是，它尚未在上游被合并，但我希望它会很快发生.有关更多信息，请尝试在虾Google网上论坛中搜索模板".

I have a prawn branch that has this functionality. Unfortunately it's yet to be merged upstream, but I'm hopeful it will happen soon. For more information, try searching the prawn google group for "templates".
