GetDocumentInfo From stream


Is it possible to call GetDocumentInfo from a stream? At the moment it seems that it is only possible to do this on an actual file, whereas in our usecase (chunked files stored) we have been able to do this using streams.

If this is not possible, is there an absolute requirement to use the document information? or can i just pass back basic information such as the page numbers, etc.?

I’m also not sure if you’re intending for your customers to make use of the showcases as-is but there are a number of critical security flaws in them. Please contact me privately and/or give me a pgp key for more info.

this is the method:

I thought as much re. the github project, but always good to make sure. Thanks for the quick reply. I’ve also noticed in the trial that calling GetDocumentInfo will also generate a file (fd.xml) in APP_DATA by default. Is there any way to change/specify the location of this file?

Thanks for the quick reply, and looking forward to hearing from the product team.
