如何替换pdf文件中的文本？ [英] How to replace text within a pdf file?

问题描述

是否可以使用Google Apps脚本替换PDF文件中的文本？

我试着在替换时没有成功，下面的代码看起来像字符串以我无法理解的方式编码。

  var pdfFile = DocsList.getFileById（pdf-doc-id）; 
 var asBlob = pdfFile.getBlob（）; 
 var asString = asBlob.getDataAsString（）; 
 var s2s =旧字符串; 
 var s2r =new string; 
 var repString = asString.replace（s2s，s2r）; 
 var repBlob = Utilities.newBlob（repString）.setContentType（application / pdf）。setName（Testing）; 
 DocsList.createFile（repBlob）; 
  

EDIT1：我得到一个空的pdf回来

任何想法？

谢谢

解决方案

c $ c> getDataAsString（）不返回PDF文件的文本内容，而是返回文件二进制内容的文本表示。该功能适用​​于任何文件，甚至那些没有文本的文件（如图片）。

不幸的是，我认为你完全可以用Apps Script来完成你的目标。如果您可以使用云端硬盘用户界面将Google PDF导入为PDF文档，那么您可以使用Apps脚本的DocumentApp修改文档并将其作为PDF导出。

Is it possible to replace text within a pdf file using Google Apps Script?

I am trying the following code without success on the replace, it seems like the string is encoded in a way I cannot understand.

  var pdfFile = DocsList.getFileById("pdf-doc-id");
  var asBlob = pdfFile.getBlob();
  var asString = asBlob.getDataAsString();
  var s2s = "old string";
  var s2r = "new string";
  var repString = asString.replace(s2s, s2r);
  var repBlob = Utilities.newBlob(repString).setContentType("application/pdf").setName("Testing");
  DocsList.createFile(repBlob);

EDIT1: I got an empty pdf back

Any ideas?

Thanks

解决方案

The function getDataAsString() doesn't return the textual content of a PDF file, but instead a textual representation of the binary content of the file. That function works on any file, even those that don't have text (like images).

Unfortunately I don't think you can fully accomplish your goal with Apps Script. If you are able to import your PDF as a Google Document using the Drive UI, then you can use Apps Script's DocumentApp to modify the document and export it as a PDF.
