Expected behavior

.hyperlinks should work on CroppedPage objects and it should only return hyperlinks contained within the cropped area

Environment

• pdfplumber version: 0.11.2
• Python version: 3.9.18
• OS: Linux

Many thanks for flagging this in such a clear and reproducible bug report, @Safrone. Should be fixed now on the develop branch in e5737d2, and will go in the next release.

This does avoid raising an exception, though it does not appear that hyperlinks are filtered based on cropped area:

reproducible example of what I mean:
