Rotate PDF fails if /Rotate is set to an IndirectObject

[kgengler]

Some example page objects below:

This works because '/Rotate' is set to an integer value
{'/Contents': IndirectObject(5, 0), '/Rotate': 270, '/Type': '/Page', '/Resources': IndirectObject(6, 0), '/CropBox': [0, 0, 612, 792], '/Parent': IndirectObject(1, 0), '/MediaBox': [0, 0, 612, 792]}

This will work because '/Rotate' is missing and get will return the default 0 value
{'/Parent': IndirectObject(3, 0), '/Contents': IndirectObject(4, 0), '/Type': '/Page', '/Resources': IndirectObject(6, 0), '/MediaBox': [0, 0, 612, 792]}

But if you encounter a case where '/Rotate' gets set to an IndirectObject such below:
{'/Contents': IndirectObject(2, 0), '/Rotate': IndirectObject(12, 0), '/Type': '/Page', '/Resources': IndirectObject(3, 0), '/CropBox': [0, 0, 603, 751], '/Parent': IndirectObject(13, 0), '/MediaBox': [0, 0, 603, 751]}

PyPDF2 throws an exception when attempting to rotate the page.

Example Code:

pdf_reader = PyPDF2.PdfFileReader('broken.pdf')
for page_num in range(pdf_reader.numPages):
    page = pdf_reader.getPage(page_num)
    page.rotateClockwise(90)

Output:

Traceback (most recent call last):
  File "./main.py", line 26, in <module>
    page.rotateClockwise(90)

Opened #338

[MartinThoma]

Now that #338 is merged + released, can somebody check if the issue still exists?

Can somebody maybe share an example PDF + code that was showing the issue?

I believe this was fixed. Please let me know if it wasn't.
