Describe the bug

When i try to convert some pages from opened pdf to images using to_image() method it throws the follwoing error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\jjjku\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\site-packages\pdfplumber\page.py", line 381, in to_image

    wand = library.NewMagickWand()
OSError: exception: access violation writing 0x0000000000000008
>>>

I tried to invoke this method from PyCharm and from windows cmd ant the result is the same.

Code to reproduce the problem (code I used in cmd)

>>> import pdfplumber
>>> myPDF = pdfplumber.open("scansmpl.pdf")
>>> myPDF.pages[0].to_image()

PDF file

Basically it occured for any pdf file I tried.

scansmpl.pdf

Expected behavior

Rather not an error but image object

Actual behavior

Error was thrown

Environment

• pdfplumber version: [0.7.4]
• Python version: [ 3.10.6]
• OS: [Windows 10]

Additional context

If it was not a bug but something wrong on my side then sorry. I tried to find the solution to the problem on my side but without results. I have Magic Wand and Ghostscript installed and environment variable for Magic Wand is set, so I don't know what more can be the cause of this issue.

Hi @jjjkuba, and thanks for the well-described report. The error appears to stem from one of this library's dependencies, Wand, and appears to have been fixed recently: emcconville/wand#586 & emcconville/wand#587

If you pip install -U wand, does that resolve the error?

[jjjkuba]

Yes, it solved the issue.
Thanks

Hello,
for me it still doesn't work. working with google colab, installed with pip - pdfplumber, imagemagick.
had the same error as here, as suggested above ran-
!pip install -U wand

my code looks like this-

import pdfplumber

pdf = pdfplumber.open("file.pdf") # Import the PDF.
page = pdf.pages[0] 
im = page.to_image()
im

and now I get this error -

---------------------------------------------------------------------------

@maayansharon10 Your issue appears to be different than the one discussed here. Instead, please see this thread: #81 (comment)

Does that help?
