Christine Straub	94fbbed189	feat: bbox shrinking in xycut algo, better natural reading order (#1560) ... Closes GH Issue #1233. ### Summary - add functionality to shrink all bounding boxes along x and y axes (still centered around the same center point) before running xy-cut sort ### Evaluation Run the followin gcommand for this [PDF](https://utic-dev-tech-fixtures.s3.us-east-2.amazonaws.com/pastebin/patent-11723901-page2.pdf).

cragwolfe	d0749d181f	fix: avoid PDF sorting error on negative coords (#1361) ... The default sorting algorithm for PDF's, "xycut," would cause an error when partitioning a document if Y coordinate points were negative. This change checks for that condition (or more broadly, any negative coordinates) and falls back to the "basic" sort if that is the case. This PR does not address the underlying issue of "bad points" which still should be investigated. However, the sorting code should be less brittle to unexpected bounding boxes in the first case.

Yao You	9191be7ae8	[issue 1237] fix empty coordinates break sorting bug (#1242) ... This PR resolves #1237 by checking if any coordinates are `None`; if yes do not attempt to sort with xy cut method and return the list as is.	2023-09-01 03:15:10 +00:00
