a test-pdf I got fromhttp://www.orimi.com/pdf-test.pdf was processed fine

what is the reason for this error, since it can't come from code?

Hello,

My Request is 17 month old, I'm using the recent release Version 15.4460.0.20 still, this problem is not fixed. I'm quiet disapointed.

Hi Raymond, 

The patch for the issue “Unexpected token object start before 24 when loading the document” has been already included in the product version 15.4460.0.20( volume 3 service pack 1, 2016 release).  

 

Since the previously provided document is corrupted, we should load the document with OpenAndRepair parameter, please refer below snippet for your reference. 

 

PdfLoadedDocument document = new PdfLoadedDocument(docStream, true); 

UG Link: https://help.syncfusion.com/file-formats/pdf/loading-and-saving-document#opening-a-corrupted-pdf-document 

Note: The OpenAndRepair overload is capable of resolving basic cross reference offset issues and cannot repair complex document corruption. 

Please let us know if you need any further assistance.
