Core Api PDF/A3 lost

Hello,
i write XMP Data into a PDF/A3. After that, it's no longer a PDF/A3.
I tried the following:
(1) Open the PDF/A3, do nothing and write in new file, PDF/A3 lost.
(2) Open the PDF/A3, do nothing and write in same file, PDF/A3 not lost.
Code: Select all
pDoc = pInst.OpenDocumentFromFile(sFilePath, Nothing, Nothing, 0, 0)
pDoc.WriteToFile(PdfFileOut, Nothing, 0)
What am I doing wrong?
Best Regards,
edvschu

Are you using latest build (315) of the Core API ? I just checked and cannot reproduce the issue.
Can you send me your file as it might be file specific issue?

I use last Build (315) of Core Api.
Problem with writing in same/new file are resolved. But writing XMP Data resulting in the loss of PDF/A3 Format.
I do this:
Code: Select all
Dim pDoc As LIBNAME.IPXC_Document = OpenDocumentFromFile(sFile, pdfInst)
If pDoc Is Nothing Then
Return
End If
Dim Meta As LIBNAME.IPXC_XMPMetadata = pDoc.GetXMPMetadata
Dim sSchemaZUGFeRD As String = System.IO.File.ReadAllText(sFileDir & "ZUGFeRD_extension_schema.xmp")
Dim sptr As IntPtr = Marshal.StringToHGlobalAnsi(sSchemaZUGFeRD)
Dim iDataSize As UInteger = Convert.ToUInt32(sSchemaZUGFeRD.Length)
Dim memBlock As LIBNAME.IMemBlock = auxInst.CreateMemBlock()
memBlock.SetData(sptr, iDataSize)
Meta.SetXMP(memBlock)
pDoc.WriteToFile(sFileXMP)
pDoc.Close()
Can anyone help?
Regards,
edvschu

As I see your code replaces XMP metadata, not append it.
And your XMP block has no:
Code: Select all
<rdf:Description rdf:about=""
xmlns:pdfaid="http://www.aiim.org/pdfa/ns/id/">
<pdfaid:part>3</pdfaid:part>
<pdfaid:conformance>B</pdfaid:conformance>
</rdf:Description>
block.
Also there some issues with editing PDF/A documents - some methods prevents PDF/A documents modification.
Will fix this issue, and will add a method to add blocks to existing XMP metadata.

Thanks for information.
Which method i must use for appending?
From Adobe there are an XMP SDK. I append these XMP Data on these PDF. The XMP Block was no required.
Must it be done differently with Core Api?
What do you mean with 'fix this issue'?

Hello, edvschu.
As Ivan said, we will add a method to append blocks to existing XMP metadata in the future build.
As for the 'issue fix' - it's about 'some methods prevent PDF/A documents modification'.
