Hi,

I want to add some xmp data to Pdf's.

I saw that you can set custom metadata using:

QP.SetInformation(.,.);

But my question is: Can I set xmp metadata, using a xmp schema with properties, fields and values?

Thanks,

Evert-Jan Modderkolk

We don't have direct functions but you could use QP.GetDocumentMetadata to get the XMP metdata, then using something like MSXML to add the values that you need and then call QP.SetDocumentMetadata.

Hi Andrew,

thanks that works.

But I was testing it, adding values of more than one schema, then it goes wrong.

So when I only add the values of the first schema to the xml and save it in the pdf als xmp, save the pdf. It goes ok. When I later open that file and add the values of the second schema to the saved file, it goes ok too.

But when I add the values of the two schemas in one run, no xmp is left in the Pdf.

What can be the reason?
