AssertionError on using fitz.IRect

[psambit9791]

Background

I am using a column-by-column parsing of PDF text as described in this link from the pymupdf repository . This has a segment where fitz.IRect is called using bounding box values. On running the code, I get assertion error from the convert(x) function.

To Recreate:

b = {'number': 0, 'type': 0, 'bbox': (403.3577880859375, 330.8871765136719, 541.2731323242188, 349.5766296386719), 'lines': [{'spans': [{'size': 14.0, 'flags': 4, 'font': 'SFHello-Medium', 'color': 1907995, 'ascender': 1.07373046875, 'descender': -0.26123046875, 'text': 'Inclusion and diversity', 'origin': (403.3577880859375, 345.9194030761719), 'bbox': (403.3577880859375, 330.8871765136719, 541.2731323242188, 349.5766296386719)}], 'wmode': 0, 'dir': (1.0, 0.0), 'bbox': (403.3577880859375, 330.8871765136719, 541.2731323242188, 349.5766296386719)}]}
bbox = fitz.IRect(b["bbox"])

Thanks for the report.

This looks like an assert that is too strict - it fails if we try to construct an IRect from floating point values. I have a fix in my tree.
