I don't know if this is the right place to report errors in GT (not assets).

Also, I am not sure if this is a systematic error or a singular phenomenon.

In euler_rechenkunst01_1738, page phys_0005 region TextRegion_1475759982805_45, the first line line_1475759982883_47 is bogus: its y coordinates extend only 2 pixels, and its TextEquiv is empty.

Yes, it is.

We should have heuristics to check for

  • polygon containment (overlapping regions, wordf outside line etc.)
  • artifacts from annotation like point or line-like regions

Another example in the same document: page phys_0003 region TextRegion_1475753831444_264 line line_1475753831522_266 is only 5 pixels in height and has empty TextEquiv, too.
