我正在编写一个小的脚本,需要合并许多一页的pdf文件。我希望脚本与Python3一起运行,并具有尽可能少的依赖关系。
对于PDF合并部分,我尝试使用PyPdf。但是,Python 3支持似乎有问题。它无法处理inkscape生成的PDF文件(我需要)。我已经安装了PyPdf的当前git版本,并且以下测试脚本不起作用:
import PyPDF2
output_pdf = PyPDF2.PdfFileWriter()
with open("testI.pdf", "rb") as input:
input_pdf = PyPDF2.PdfFileReader(input)
output_pdf.addPage(input_pdf.getPage(0))
with open("test.pdf", "wb") as output:
output_pdf.write(output)
它引发以下堆栈跟踪:
Traceback (most recent call last):
File "test.py", line 7, in <module>
output.addPage(input.getPage(0))
File "/usr/lib/python3.3/site-packages/pyPdf/pdf.py", line 420, in getPage
self._flatten()
File "/usr/lib/python3.3/site-packages/pyPdf/pdf.py", line 574, in _flatten
self._flatten(page.getObject(), inherit)
File "/usr/lib/python3.3/site-packages/pyPdf/generic.py", line 165, in getObject
return self.pdf.getObject(self).getObject()
File "/usr/lib/python3.3/site-packages/pyPdf/pdf.py", line 616, in getObject
retval = readObject(self.stream, self)
File "/usr/lib/python3.3/site-packages/pyPdf/generic.py", line 66, in readObject
return DictionaryObject.readFromStream(stream, pdf)
File "/usr/lib/python3.3/site-packages/pyPdf/generic.py", line 526, in readFromStream
value = readObject(stream, pdf)
File "/usr/lib/python3.3/site-packages/pyPdf/generic.py", line 57, in readObject
return ArrayObject.readFromStream(stream, pdf)
File "/usr/lib/python3.3/site-packages/pyPdf/generic.py", line 152, in readFromStream
obj = readObject(stream, pdf)
File "/usr/lib/python3.3/site-packages/pyPdf/generic.py", line 86, in readObject
return NumberObject.readFromStream(stream)
File "/usr/lib/python3.3/site-packages/pyPdf/generic.py", line 231, in readFromStream
return FloatObject(name.decode("ascii"))
File "/usr/lib/python3.3/site-packages/pyPdf/generic.py", line 207, in __new__
return decimal.Decimal.__new__(cls, str(value), context)
TypeError: optional argument must be a context
但是,相同的脚本可以完美地在Python 2.7中使用。
我在这里做错了什么?这是库中的错误吗?我可以解决该问题而无需接触PyPDF库吗?
最佳答案
所以我找到了答案。 Python3.3中的decimal.Decimal
模块显示了一些奇怪的行为。这是相应的StackOverflow问题:Instantiate Decimal class我向PyPDF2库添加了一些解决方法,并提交了请求请求。
