I get nothing from this PDF. No Text or Table

[robbanp]

I'm not sure why, if it's the settings or data. I tried with multiple pdfs from the same source.
tst.pdf

import pdfplumber
print(pdfplumber.version)
pdf = pdfplumber.open("../data/tst.pdf")
p0 = pdf.pages[1]
p0.extract_words()

returns []

...

im = p0.to_image(resolution=75)
im

returns

p0.extract_table()

returns

[['', '', '', '', '', '', '', ''],
['', '', '', '', '', '', '', ''],
[None, '', None, None, None, None, None, None],
['', '', '', '', '', '', '', ''],
[None, '', None, None, None, None, None, None],
['', '', None, None, None, None, None, None],
[None, '', None, None, None, None, None, None],
['', '', '', '', '', '', '', ''],
[None, '', None, None, None, None, None, None],
['', '', '', '', '', '', '', ''],
[None, '', None, None, None, None, None, None]]

It appears that the text in that PDF is rasterized (converted from actual information about the characters to an image version of them). You can test this by opening the PDF in standard PDF-viewing software and attempting to select or copy-paste the text.

To resolve the problem, you can try running the PDF through optical character recognition (OCR) software, but be aware that pdfplumber does not work as well with OCR'ed PDFs.
