How to compare two PDF

Aspose.PDF Product Family

Hi,

Currently I am using Aspose.Words to compare two PDF documents using below code.

Document baselineDoc = new Document(baselinePdfPath);
Document generatedDoc = new Document(generatedPdfPath);

// There should be no revisions before comparison
baselineDoc.AcceptAllRevisions();
generatedDoc.AcceptAllRevisions();

baselineDoc.Compare(generatedDoc, "Reports PDF Comparison", DateTime.Now);

if (baselineDoc.Revisions.Count.Equals(0))
{
    logger.Debug("Both PDF's matches");
    return true;
}
else
{
    string filePath = Path.Combine(outputFilePath, string.Concat(outputFileName, ".pdf"));
    baselineDoc.Save(filePath);
    logger.Debug($"There is a mismatch between the PDF's, the differences is saved in the file - {filePath}");
    return false;
}

We have Aspose.Total license. Wanted to check is there other ways to compare two PDF documents for equality and print/highlight the differences.

Thanks,

Unfortunately, Aspose.PDF does not support the PDF comparison feature. We logged this feature request as PDFNET-38669 in our issue tracking system. However, you can please check the document comparison API of GroupDocs, a venture of Aspose.
