1.1.4

What's Changed

The main change is the detection of horizontal and vertical lines and their exclusion from the mask expansion to avoid the inclusion of whole tables when chemical structures are placed in them. Additionally, the segments are now sorted in the intuitive reading order thanks to @deimos1078.

• Update docstrings by @OBrink in #68
• top down, left right reading ordered segments by @deimos1078 in #72
• fix crash-inducing bug introduced with #72 by @OBrink in #75
• Horizontal vertical line exclusion by @OBrink in #77
• fix: handle failed mask center determination #63 by @OBrink in #78
• Development by @Kohulan in #79
• fix: smaller threshold for definition of long vertical or horizontal lines by @OBrink in #80
• fix: fix broken test case by @OBrink in #81
• fix: avoid crash during mask application by @OBrink in #82
• version bump: 1.1.3 --> 1.1.4 by @OBrink in #83

New Contributors

• @deimos1078 made their first contribution in #72
• @Kohulan made their first contribution in #79
