Hi, i’m trying to convert a PNG/JPEG/GIF to PDF in PDF/A-1a format. Unfortunately the test failed:

    @Test
    void testImageToPdfA1a() throws IOException {
        try(ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {
            Resource inputDocument = new ClassPathResource("sampleInput.png");

            Image image = Image.load(inputDocument.getInputStream());

            PdfOptions pdfOptions = new PdfOptions();
            PdfCoreOptions pdfCoreOptions = new PdfCoreOptions();
            pdfCoreOptions.setPdfCompliance(PdfComplianceVersion.PdfA1a);
            pdfOptions.setPdfCoreOptions(pdfCoreOptions);

            image.save(outputStream, pdfOptions);

            InputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray());

            assertThat(new Document(inputStream).validate(outputStream, PdfFormat.PDF_A_1A)).isTrue();
        }
    }

Does anyone knows what i’m doing wrong ? For PDF/A-1b it is working:

    @Test
    void testImageToPdfA1b() throws IOException {
        try(ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {
            Resource inputDocument = new ClassPathResource("sampleInput.png");

            Image image = Image.load(inputDocument.getInputStream());

            PdfOptions pdfOptions = new PdfOptions();
            PdfCoreOptions pdfCoreOptions = new PdfCoreOptions();
            pdfCoreOptions.setPdfCompliance(PdfComplianceVersion.PdfA1b);
            pdfOptions.setPdfCoreOptions(pdfCoreOptions);

            image.save(outputStream, pdfOptions);

            InputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray());

            assertThat(new Document(inputStream).validate(outputStream, PdfFormat.PDF_A_1B)).isTrue();
        }
    }

I’m using JDK 17 or 21 and
Maven: com.aspose:aspose-imaging:jdk16:23.10 (aspose-imaging-23.10-jdk16.jar)

Hello, @KevinK!
We appreciate your interest in Aspose.Imaging.
Could you send me the error you faced? Or stack trace? Or source png file?

Best regards

ConvertDocumentToPDFServiceTest.sampleInput.png.zip (30,7 KB)

Thank you, let me take a look at this.

I have tested your examples. It produced correct PDF files in both cases, and Adobe PDF Reader can open them. The reason for the error in validating I can not explain, I think you should relay this question to the Aspose.PDF team.
Let me know if I can do more for you.
Best regards

Hello @evgeniy.sidenko,
first of all, thank you for your help. But here a few questions:

  • How can you verify, that the outcome document is in the a PDF/A-1a format ?
  • How can i reach the Aspose.PDF Team ?

If i upload the document to PDF/A validator | PDFen.com then i get

CHECK FAILED
THE DOCUMENT DOES NOT CONFORM TO THE PDF/A-1A STANDARD.

Thank you!

@KevinK
I open the output PDF file with Adobe Acrobat Reader and it says that it is PDF/A-1a and only for reading.
Ok, we are going to check it out with PDF/A validator | PDFen.com
You can write this question to this forum in the “Aspose.PDF Product Family” branch.
