negative region coordinates and empty regions

[jahtz]

After running the script, I noticed some negative coordinates, not enough coordinates and some empty regions.

negative coordinates:

<TextLine id="r1l31" custom="readingOrder {index:28;}">
    <Coords points="304,4432 2797,4482 2799,4365 1058,4337 -1323,4351"/>
    <Baseline points="320,4410 443,4412 566,4414 689,4416 812,4418 935,4421 1058,4422 1181,4424 1304,4426 1427,4428 1550,4430 1673,4434 1796,4436 1919,4438 2042,4442 2165,4446 2288,4450 2411,4454 2534,4460 2657,4464 2780,4470"/>
    <TextEquiv>
        ...

-> Value '304,4432 2797,4482 2799,4365 1058,4337 -1323,4351' is not facet-valid with respect to pattern '([0-9]+,[0-9]+ )+([0-9]+,[0-9]+)' for type 'PointsType'.

not enough coordinates and empty regions:

<TextRegion id="region_1535370511662_1" custom="readingOrder {index:1;}">
    <Coords points="206,1554"/>
        <TextEquiv>
            <Unicode/>
        </TextEquiv>
</TextRegion>

-> Value '206,1554' is not facet-valid with respect to pattern '([0-9]+,[0-9]+ )+([0-9]+,[0-9]+)' for type 'PointsType'.

ty!

Could you please append an example PAGE file which can be used to reproduce the issue?

Sorry for the delay. The files are attached below.

Thank you very much!
