[SOLVED] pdfplumber im.show doesn't work but im.save() works fine

Actually, I'm trying to get table data from a pdf, but the table has not borders. Turns out, it is quite tricky to pick up the empty cells as well! But that's not relevant here!

The documentation for pdfplumber at PyPi clearly states that im.show() should work.

pdf1 = pdfplumber.open(path2pdf + my_pdf)
page = pdf1.pages[0]
cropped_page = page.crop(bounding_box)
im = cropped_page.to_image(resolution=150)
im.save(path2pdf + "test1.png", format="PNG")

The documentation also says change /etc/ImageMagick-6/policy.xml from

<policy domain="coder" rights="none" pattern="PDF" />

to

<policy domain="coder" rights="read|write" pattern="PDF" />

I did that, rebooted to be sure the new policy was loaded.

But still im.show() won't work. This in the Idle shell:

>>> im.show() Traceback (most recent call last): File "/usr/lib/python3.8/idlelib/run.py", line 559, in runcode exec(code, self.locals) File "<pyshell#19>", line 1, in <module> AttributeError: 'PageImage' object has no attribute 'show' >>>

Like I said, I can save the cropped page image.

Any ideas why im.show() won't work?

I do a similar thing for my little multi-choice answer form programme and there im.show() works.

Later, I remembered, I had a similar problem before.

After installing a module, I noticed that im.show() would not work.

I ran the programme in a VENV, then it worked!

So solved!
