PDF/A Knowledge

Hi All

Can anybody with PDF/A knowledge help out with https://issues.apache.org/jira/browse/PDFBOX-2442 as without a copy of the spec I’m blind.

Does the PDF/A spec add anything beyond that sentence? As it’s already in the PDF spec.
The thing is, that the widths definitely do not match, but the file passes Adobe’s Preflight.

The only thing I can think of is that when the Widths entry has the glyph width as zero then
the glyph is never rendered, so it doesn’t matter that the width in the font is wrong - but where
in the PDF (or indeed PDF/A) spec does it say that?

Hi John,
For every font embedded in a conforming file, the glyph width information stored in the Widths entry of the font dictionary and in the embedded font program shall be consistent.
