Examples

Example 1: Validate a file against its declared level.

using LMKit.Document.Pdf;

var report = PdfAValidator.Validate("invoice_pdfa.pdf");
Console.WriteLine($"{report.Verdict} ({report.Validator})");


foreach (var finding in report.Findings)
{
Console.WriteLine($"  {finding.Rule}: {finding.Description}");
}

Example 2: Convert, then verify the output independently.

using LMKit.Document.Pdf;

var converted = PdfAConverter.ConvertToBytes(sourceBytes);
var report = await PdfAValidator.ValidateAsync(converted.Data);


bool verified = report.Verdict == PdfAValidationVerdict.Compliant;

Remarks

Independent by construction. The validator re-parses the candidate bytes from scratch and evaluates the rule catalog against the document's actual state; it never trusts producer bookkeeping. It can therefore check files produced by PdfAConverter as well as files of unknown origin, and tell a file that merely declares PDF/A from one that holds up to the rules.

Levels. The B (basic) profiles of PDF/A-1, PDF/A-2 and PDF/A-3 are covered. With no explicit Level the level is resolved from the file's own XMP identification; a file declaring a part outside this coverage (e.g. PDF/A-4) yields Undetermined, never a false verdict.

Verdicts. Compliant means every evaluated rule passed; NonCompliant carries one PdfAValidationFinding per failed rule; Undetermined means the document could not be judged (unreadable, password required, uncovered level). RulesEvaluated states the pass's own coverage so stored verdicts stay honest.
