2008-12-10 2010-09-27 There is no sure proof way to determine if a generic pdf file is modified. If you go to the document properties (control or command d), if the proper metadata is available, it will list the creation date and time and modified date and time. This can help you determine if a pdf file has been modified since creation. However, it is not foolproof.

Code navigation not available for this commit Go to file @sylvainpelissier @Yenthe666 Hey, I am trying to use the code which extracts all the images from python.And getting NotImplementedError for /DCTDecode. I found that I am using simple PyPDF2 Library.Can you please give me the link to that particular library which resolves this? 2008-12-10 2010-09-27 There is no sure proof way to determine if a generic pdf file is modified.
