Hi @deepseek !

Thank you for the issues and the very clear example.

I have been able to reproduce negative coordinates indeed for the TextBlock element on your example. TextLine in the block are correct, I will review how these block coordinates are calculated, probably simply an absolute value missing.

is this problem solved？ I still facing block width and height with negative value

Hi @yueyub !

I think it was solved, do you have a reproducible example ? It would help a lot.

It's this paper:, https://arxiv.org/abs/2207.04630, but I think it may apply to any arxiv paper.

After extract xml file,

search "arXiv:2207.04630v2", it's on the first page, the block coordinates is :

<TextBlock ID="p1_b17" HPOS="18.3400" VPOS="443.790" HEIGHT="-443.79" WIDTH ="-18.340">

How to understand the negative height and width?

Thank you very much @yueyub for the error case. I think it's just a bug (a missing absolute value for the TextBlock element only) - I reproduce it with your example for the @WIDTH and I will fix it.
