How can I validate if a stream is a valid pdf document?

Aspose.PDF Product Family

Hello,

So, are there any methods that can validate if a stream is a valid pdf document? With Aspose.Words I can use the method DetectFileFormat() and catch the UnsupportedFileFormatException when I instantiate the Document class to verify if a stream is a valid word document. And with Aspose.Pdf.Kit, is there something like that?

Thank you!

Regards,

André

Hi André,

If you want to know whether the input file stream is in a valid PDF file format, then you can capture the IOException in your code. When the input file is not in a valid format, you’ll receive the following message:

"Invalid pdf format:pdf head signature is not found!: v3.5.0.0"

However, I’m afraid that there is no exception class defined for this purpose in the current version of Aspose.Pdf.Kit.

If you have any further questions, please do let us know.

Regards,
