【背景】

折腾：

期间，去试试使用pyPdf去把一个不可复制的PDF文件，转换为文本或HTML。

【折腾过程】

1.参考：

去找到：

并下载：

2.但是安装时找不到Python：

看来是：

我此处安装的x64的python，此处无法识别啊。。。

3.重新下载：

然后去解压安装：D:\tmp\dev_tools\python\pdf\pyPdf-1.13\pyPdf-1.13>python setup.py install

running install

4.然后再去解决上述问题：

没找到解决办法。

其中：

说是，其代码对于其他pdf正常，所以无视此bug。。。

【总结】

目前也是无法通过pyPdf将上述不可拷贝的pdf转换为想要的文本或html。
