How to convert JPEG to PDF
Hi guys!
I have the requirement to convert JPG to PDF. I already have pyFileSource property (I think that it is like a stream). I need to convert this stream to PDF format and place it instead of old pyFileSource property. How can I do it? Thanks in advance!
P.S. I already tried different ways from PDN articles

@KALINGAROUT thank you for help!
I found other solution. Code of my function you can see below:

I found other solution. Code of my function you can see below:
//Get Engine API library
PublicAPI api = (PublicAPI) ThreadContainer.get().getPublicAPI();
//find primary page
ClipboardPage mainPage = api.findPage("pyWorkPage");
//get value of property (it's a stream of uploaded file)
String IMGstr = mainPage.getString(".FoundingDocument.pyFileSource");
String IMGname = mainPage.getString(".FoundingDocument.pyFileName");
//convert stream to byte array
byte[] ImgArray = IMGstr.getBytes();
//Prepare byte array output stream
java.io.ByteArrayOutputStream outfile = new java.io.ByteArrayOutputStream();
//Create new document
com.lowagie.text.Document document = new com.lowagie.text.Document();
try{
// Get Instance of PDF writer
com.lowagie.text.pdf.PdfWriter writer = com.lowagie.text.pdf.PdfWriter.getInstance(document,outfile);
writer.setStrictImageSequence(true);
// Open the document
document.open();
//Get array
com.lowagie.text.Image jpg = com.lowagie.text.Image.getInstance(Base64Util.decodeToByteArray(IMGstr));
//Scale the image
float scaler = ((document.getPageSize().getWidth() - document.leftMargin() - document.rightMargin()) / jpg.getWidth()) * 100;
jpg.scalePercent(scaler);
//Add image to document and finish work with document
document.add(jpg);
document.close();
//set correct values to properties
mainPage.putString(".FoundingDocument.pyFileName", IMGname + "_converted.pdf");
mainPage.putString(".FoundingDocument.pyFileType", "pdf");
mainPage.putString(".FoundingDocument.pyNote", IMGname + "_converted");
//Encode result pdf and replace it instead of uploaded JPEG
String pdfStream = Base64Util.encodeToString(outfile.toByteArray());
mainPage.getProperty(".FoundingDocument.pyFileSource").setValue(pdfStream);
outfile.flush();
}catch(Exception e){
e.printstacktrace();

@Artsiom_Sukhanau - You can try using iText to convert jpg to pdf. Pega already ships with iText jar so I don't think we need to import anything.

@KALINGAROUT hello! Thanks for your reply☺
But in that article we work with physical files
But I have a case and its clipboard. So I need to create logical PDF in Java with my pyFileSource property, convert it to stream back and replace current pyFileSource (which has stream of uploaded JPEG) with a stream of newly created PDF. So user after pressing the button "Download file" must get PDF instead of JPG.
Here is example of pyFileSource property (JPEG):
