GemBox.Document support generating only standard PDF files.
Request for supporting a PDF/A file format so that we can generate or convert input files into an output PDF/A format.
Mario at GemBox
This feature request has been implemented and is available in the latest versions of GemBox.Document.
Yes PDF/A supports vector images, just like the regular PDF does.
But unfortunately GemBox.Document currently does not convert vector image formats to PDF vector graphics (but rather to PNG).
However if/when GemBox.Document does add support for this conversion, it will be available for both PDF and PDF/A format (after support for it has been implemented).
are here any news about PDF/A? I would like to use this.
I'm afraid there is no news regarding PDF/A support.
This feature is not in our current road-map so it won't be available this year and for later I cannot say at the moment.
