ObjectID is not internal PDF ObjectID depending on PDF open mode #111

Closed jgunter7 closed 1 year ago

jgunter7 commented 4 years ago

For example, when I open a Form-Fill PDF, take this as an example: https://www.irs.gov/pub/irs-pdf/f1040.pdf

Depending on if I use PdfDocumentOpenMode.Modify, or PdfDocumentOpenMode.ReadOnly, a specific field I am looking for has a different ObjectID. Note, I get the correct Object ID when using "ReadOnly" mode.

I am viewing ObjectID's using CosEdit, and I can reproduce this issue when printing out the AcroForm field ObjectID's when opening the PDF file in different modes.

This is by design. Objects should be addressed by Name, not by ID.
