PDF/A-1b compatibility

[LosBubos]

Hello,

I have a problem to convert a document to pdf/a. The option is set for
the printer driver PXCComLib.CPXCPrinter via COM API (version 4.0.154.0).
Both of the following definitions don't work: "PDFA-1b" and "PDF/A-1b".

I have checked both versions on two different validators "http://www.soliddocuments.com" and on "PDF Validator vom PDF Tools", but I get error messages:

With the option: ....Option("General.Specification") = "PDFA-1b"
PDF Validator / PDF Tools:
The error message: "The separator before 'endtstream' must be an EOL."

The error message: "File structure Stream dictionary length value and detected stream length mismatch"

---------------------------------------------------------------------------------------------------------
With the option ....Option("General.Specification") = "PDF/A-1b"

PDF Validator / PDF Tools:
The error message: "The key Metadata is required but missing."


The error message:
"File structure Stream dictionary length value and detected stream length mismatch"
"Catalog The key <<OutputIntents>> is required for PDF/A-1b"
"Catalog The key <<Metadata>> is required for PDF/A-1b"

Any help is appreciated....thanks in advance.

Hi,

can you please supply a small and simple example (zipped) - direct to Ivan@tracker-software.com with a link back to this forum topic in the messsage body

with any necessary instructions/info.

thanks

Valid value for Option("General.Specification") is "PDFA-1b", not "PDF/A-1b".

Can you send me document created with this option?

Hi Ivan,

Yes, I had. And see strange things: Acrobat 8 says file conforms PDF/A-1b specification. Acrobat 9 - says not, and says that problems are with new lines/line feeds into streams.

But, when I take a look at PDF/A-1b ISO specification there is:

3.6 end-of-line marker
EOL marker
one or two character sequence marking the end of a line of text, consisting of a CARRIAGE RETURN character (0Dh) or a LINE FEED character (0Ah) or a CARRIAGE RETURN followed immediately by a LINE FEED.

....

6.1.7 Stream objects
The stream keyword shall be followed either by a CARRIAGE RETURN (0Dh) and LINE FEED (0Ah) character sequence or by a single LINE FEED character. The endstream keyword shall be preceded by an EOL marker.
The value of the Length key specified in the stream dictionary shall match the number of bytes in the file following the LINE FEED character after the stream keyword and preceding the EOL marker before the endstream keyword.
NOTE 1 These requirements remove potential ambiguity regarding the ending of stream content.

So, by ISO specification (hope it is common for all) our PDFs conform to PDF/A-1b (we are using 0Ah after stream, and 0Ah before endstream).

Hello Ivan,

this is peterandree, workmate of LosBubos.

We created documents with the most recent update of your software. It's still not working. There just is no EOL marker before endstream which you say should be the case. Could you please verify that everything is working as it should and recommend a possible solution to the issue?

[Ivan - Tracker Software]

Can you send me PDF without EOL marker before endstream (please use Ivan@tracker-software.com)? Please note, EOL marker is: 0Dh, 0Ah or sequence 0Dh,0Ah.

Thanks, fixed. Fix will be available in days into build 156.
