Default Pulling TIFF file from path in ORM and writing it to another directory.

Hi All,

Looking for some guidance if possible.

I am receiving the following ORM which has a file path to a .tiff which I would like to pull out and write to another folder (or if I could convert the TIFF to a PDF and write to a folder, even better).

Would anyone be able to give some guidance on how to go about this?

I have tried adding the following into the Destination Transformed but I think I am way off:

var fileName = "msg['OBX'][1]['OBX.5']['OBX.5.1'].toString()"

var directory = "E:\Inbound" 
var outFileName = "test.tiff";
var destination = directory +"\\" + outFileName

//var file = new java.io.File(directory);
var inputFile = new File(fileName);
var outputFile = new File(destination);

I would channelMap the variables so you can verify the contents. Or use logger.info()

your message indicates that you have to pull the file from a SMB-Share
So you have to use the CIFS-library.

var fn=msg['OBX'][i]['OBX.5']['OBX.5.1'].toString().replace(/\\E\\/g,"/").replace(/\/\//,"smb://youtusername:yourpassword@");
var file=new Packages.jcifs.smb.SmbFile(fn);
var inputStream=file.getInputStream();
var byteArray = IOUtils.toByteArray(inputStream);
Don't forget to change yourusername and yourpassword to your appropriate credentials :-)

You now have a Java byte array representing your TIFF-File

As for converting this to PDF:

var doc = new org.apache.pdfbox.pdmodel.PDDocument();

var seekableStream = new Packages.com.sun.media.jai.codec.ByteArraySeekableStream(byteArray);
var imageDecoder = ImageCodec.createImageDecoder("tiff", seekableStream, null);
for (var i=0; i < imageDecoder.getNumPages(); i++) {
	var renderedImage = imageDecoder.decodeAsRenderedImage(i);
	var page = new Packages.org.apache.pdfbox.pdmodel.PDPage();
	var contentStream = new Packages.org.apache.pdfbox.pdmodel.PDPageContentStream(doc, page);
	var image = Packages.org.apache.pdfbox.pdmodel.graphics.image.LosslessFactory.createFromImage(doc, javax.media.jai.PlanarImage.wrapRenderedImage(renderedImage).getAsBufferedImage());
     	contentStream.drawImage(image, 1, 1, 600, 750);
var ba = new java.io.ByteArrayOutputStream();
var att=addAttachment(Packages.org.apache.commons.codec.binary.Base64.encodeBase64(ba.toByteArray(),false),"PDF");
All this results in an attachment containing your converted PDF-File, which you can even view with Mirth's PDF-Viewer
It looks a bit streched - but not being a graphics person I have no idea what these parameters in drawImage mean.
I just want to show you one possible way and this was the first one I found in stackoverflow.

You have to put sun-jai_codec.jar and sun-jai_core.jar into your resources directory.
