Code: [Select]
//scan.pdf is just my file name
//Same error happen in the code when using
PdfParser p = new PdfParser(IvyDocumentReader.ReadPdf("scan.pdf"));

Hi, thank you so much for the prompt reply.

The 1.50 beta did address the error "Error: The given key was not present in the dictionary" but it did also create some discrepancy between 1.49 and 1.50.

Let take this file for example,
https://drive.google.com/file/d/1OSbz3JV4KVqhuJd_28IhfqrglOp5Ru-e/view?usp=sharing

When 1.49 parse the file above, page 66 did have the table border properly preserved. Please see
https://drive.google.com/file/d/1rWuvaruphJQHRDJu15yMH3vEwAw5PIwh/view?usp=sharing

When 1.50 beta, same file, the lines(borders) on page 66 are stripped away
https://drive.google.com/file/d/1-PR4M0jUjPs7izLkyRUnv3cQg9g4dSmb/view?usp=sharing

In this scenario, I think 1.49 has more accurate result - this somehow affect the "EnclosedArea()" logic in my code.

Thank You - for the amazing library!

Hi,

Thank you for the sample files! It turned out there was a change in version 1.50 related to processing sub-streams in PDF documents, which caused this problem.
It should be fixed now. Please try this version:

Please let me know if you notice any other issues!

Thank you,
Andrew
