Is there a function to determine the pdf/a - conformance of an existing file.

To get for example: pdf/a 2a, pdf/a 1b, ...

APDF - Adobe PDF Library (as licensed by DataLogics).

API is identical to the Acrobat plug-in API, except without any UI. Also without file conversions and preflighting (which is what does PDF/A validation).

Karsten - do you actually want to see if a file claims to be PDF/A (includes the PDF/A marker), or do you want to check whether a file claiming to be PDF/A conforms to all of the requirements in the ISO standard?

Thanks for answering so far.

The Adobe PDF Library has functions to convert pdf-files into a pdf/a conform standard.

typedef enum {
/** Convert to PDF/A-1a RGB */
kPDFProcessorConvertToPDFA1aRGB,
/** Convert to PDF/A-1a CMYK */
kPDFProcessorConvertToPDFA1aCMYK,
/** Convert to PDF/A-1b RGB */
kPDFProcessorConvertToPDFA1bRGB,
/** Convert to PDF/A-1b CMYK */
kPDFProcessorConvertToPDFA1bCMYK,
/*DLADD 29Jul2019 - Added new options for Part 2 and Part 3.*/
/** Convert to PDF/A-2b RGB */
kPDFProcessorConvertToPDFA2bRGB,
/** Convert to PDF/A-2b CMYK */
kPDFProcessorConvertToPDFA2bCMYK,
/** Convert to PDF/A-2u RGB */
kPDFProcessorConvertToPDFA2uRGB,
/** Convert to PDF/A-2u CMYK */
kPDFProcessorConvertToPDFA2uCMYK,
/** Convert to PDF/A-3b RGB */
kPDFProcessorConvertToPDFA3bRGB,
/** Convert to PDF/A-3b CMYK */
kPDFProcessorConvertToPDFA3bCMYK,
/** Convert to PDF/A-3u RGB */
kPDFProcessorConvertToPDFA3uRGB,
/** Convert to PDF/A-3u CMYK */
kPDFProcessorConvertToPDFA3uCMYK
} PDFProcessorPDFAConversionOption;

PDFProcessorConvertAndSaveToPDFA()

But i found no function to check the current pdf/a conformance of an existing pdf-file. So, before i convert a file to the wanted pdf/a conformance, i need to consider the file.

I can parse the file by myself and search for <pdfaid:part> and <pdfaid:conformance>, but that's not what i wanted.

Is there a way to check this by Adobe PDF Library or some other c++ Library?
