Block length does not match with its complement

Hi,

When I use the aspose.pdf and create document and load the pdf using EssentialObjects.PDFDocument(), it is throwing the following error.

Block length does not match with its complement.

Is there any measures that need to be taken from aspose while saving the file.

Could you please.

Below is the implementations:

Hi,


Thank you for contacting support. Kindly share the input PDF, image and complete code. Your code is not in fully compilable form because the “wholedata” object is not defined. We need to replicate the same issue in our environment, and then we will be able to investigate and fix it. Your response is awaited.
