Error saving in linearized format

Hi all,

I am copying the pages of a 81284 page pdf file, and saving to a new file with linearization. However, the save call came back with an exception during execution:

Exception: An error occurred during linearization: Operation file seek failed

What possible causes are there for the save command to fail with this error? I’ve attached my python code below.

new_doc = PDFDoc()

doc = PDFDoc("./test.pdf")


copy_pages = VectorPage()

itr = doc.GetPageIterator()

while itr.HasNext():

page = itr.Current()



imported_pages = new_doc.ImportPages(copy_pages)

i = iter(imported_pages)

for x in i:



new_doc.Save("./test_resave.pdf", SDFDoc.e_linearized)


I know that it may be difficult to debug this without the original pdf, so just pointing me at possible causes of this error message would be great. I cannot provide the pdf itself without approval from management, as it has confidential information in it.

Thanks for building an excellent product!

Are you using the latest version (i.e. v.5.8 or higher - There were some files which were causing similar errors in older versions of the library. If upgrading does not help, we would need to take a look at the file to diagnose the issue.
