Converting images to PDF using AEM services

Hello!

For our projects at the Finanzinformatik in Frankfurt we need to convert PDF documents with
barcode to an image format and back to PDF for automated comparison. Converting PDF to image is working fine.

But how can an image be converted into a PDF document using AEM services?

I have been researching ways with AssemblerService by calling invoke method with DDX
and GeneratePdfService, but it only seems to be supported for some office document types.

Is there a solution for converting images into PDF, perhaps with a little code example?

That would be very helpful!

Thanks!

The javadoc is here for the API

The following is sample JSP code

ToImageOptionsSpec spec = new com.adobe.fd.cpdf.api.ToImageOptionsSpec();

       System.out.println("$$$$$$$Successfully set the image spec");
spec.setImageConvertFormat(ImageConvertFormat.JPEG);
spec.setGrayScaleCompression(GrayScaleCompression.Low);
spec.setColorCompression(ColorCompression.Low);
spec.setFormat(JPEGFormat.BaselineOptimized);
spec.setRgbPolicy(RGBPolicy.Off);
spec.setCmykPolicy(CMYKPolicy.Off);
spec.setColorSpace(ColorSpace.RGB);
spec.setResolution("72");
spec.setMonochrome(MonochromeCompression.None);
spec.setFilter(PNGFilter.Sub);
spec.setInterlace(Interlace.Adam7);
spec.setTileSize(180);
spec.setGrayScalePolicy(GrayScalePolicy.Off);
ConvertPdfService convertPdfService = sling.getService(ConvertPdfService.class);
System.out.println("$$$$$Got Convert PDF Service");
    System.out.println("Inside dummy for PDF G");
   System.out.println("The ocr value is ..."+request.getParameter("ocr"));
   SlingScriptHelper scriptHelper = bindings.getSling();
RequestParameter inputFileParam = scriptHelper.getRequest().getRequestParameter("inputDoc");
   String convert = request.getParameter("Convert");
   System.out.println("The value of convert "+convert);

       InputStream inputDocStream = null;
       String fileName = FilenameUtils.getName(inputFileParam.getFileName());
       inputDocStream = inputFileParam.getInputStream();
        com.adobe.aemfd.docmanager.Document uploadedDocument = new com.adobe.aemfd.docmanager.Document(inputDocStream);

java.util.List allImages = convertPdfService.toImage(uploadedDocument,spec);

System.out.println("@@@@@@@The number of images I got was ...."+allImages.size());

System.out.println("$$$$ Converted the PDF to Images&&&&&&");
