------------------------------------
Hi,
I started to work on this issue last week.
My first impression is that the font HiddenHorzOCR isn't well formed because the extracted FontFile doesn't have any glyph definition.
That seems to confirm the error.
Maybe I'm wrong. I will try to work on this issue this week.
I don't yet look at the Metadata error.
BR,
Eric

[jira] [Resolved] (PDFBOX-1204) OCR generated PDF/A has problems
with preflight validation
Posted by "Eric Leleu (Resolved) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/PDFBOX-1204?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eric Leleu resolved PDFBOX-1204.
--------------------------------
Resolution: Fixed
Hi,
I thank you for the link.
It helped me a lot to find the fix.
As you have said, the problem is the partial font embedded by the OCR process.
When a glyph was used in a text, an exception was thrown when the glyph was missing or when the glyph width was inconsistent. This exception should not be thrown when the Rendering Mode is set to 3. I added this condition.
I fixed the XMP error too.
Now the boyd.pdf file is considered as a valid PDF/A-1b.
BR,
Eric

-----------------------------------------
Hi Eric,
I was looking at this document:
http://www.aiim.org/documents/standards/PDF-A/ISO19005AppNotes.pdf
I was wondering with an OCR type document if only a partial font set is used and if this paragraph wouldmake any sense:
"Developers should be aware that although the PDF/A-1 specification implies that all glyphs in the embedded data must have a matching entry in the Widths table, only those glyphs actually used need to have Width entries."
so, I'm trying to understand if the above applies to the 3.3.1 error message returned.
Regards,
Bill

Hi Eric,
With issues 1110 and 1200 getting fixed, I reran my test on the boyd.pdf and still get a preflight validation error below:
/home/fausser/boyd.pdf is not valid, error(s) :
3.3.1 : Glyph error, CID 95 is missing from the Composite Font format "HiddenHorzOCR"
7.2 : Error on MetaData, ModificationDate present in the document catalog dictionary doesn't match with XMP information
OCR generated PDFs are a big part of the way PDF/As get generated and if these bugs get cleared up, I think the preflight product wiill
become usable as a valid PDF/A validator.
Regards,
Bill
