Some jpgs result in blank page once converted to PDF

Aspose.PDF Product Family
1

Hi,
I am using below code to convert jpg to pdf. But I see that the resultant PDF file is empty with only water mark appended.

I have attached a sample file for which PDF is empty.

//Code snippet
Document pdfDocument = new Document();
Page page = pdfDocument.getPages().add();
pdfPage.getPageInfo().setHeight(imHeight);
pdfPage.getPageInfo().setWidth(imWidth);
pdfDocument.getPageSetup().setOrientation(PageFormat.LANDSCAPE);
Image image = new Image();
image.setImageStream(is);
pdfDocument.getPages().get_Item(1).getParagraphs().add(image);
page.getParagraphs().add(image);
pdfDocument.save(“C:/temp/ImagetoPDF.pdf”);
saveFile(workerServlet, pdfDocument, os);

Hi,
I am using aspose-pdf-22.9-jdk16 for JAVA. I have tried the same with words jar as well. It is still empty. aspose words is aspose-words-22.9-jdk16 for JAVA

     Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);
  setPrintSettings(ps, dataProvider, printThread, book, img, builder); (I set img width , pageWidth , resolution, orientation and other attributes in this method)
   Shape img = builder.insertImage(is);
   doc.save("C:/temp/ImagetoPDF.pdf");

I’m not strong in Java - I wrote how it would look like in C#

var pdfDocument = new Aspose.Pdf.Document();
var pdfPage = pdfDocument.Pages.Add();

pdfPage.PageInfo.IsLandscape = true;

var image = new Aspose.Pdf.Image();
image.File = myDir + "Image-116.jpg";

pdfPage.Paragraphs.Add(image);

pdfDocument.Save(myDir + "image-out.pdf");

Hi,
This is a direct load from a file. But what I am trying is from an inputstream.
Shape img = builder.insertImage(is);
“is” is InputStream.

Document pdfDocument = new Document();
Page page = pdfDocument.getPages().add();
pdfPage.getPageInfo().setHeight(imHeight);
pdfPage.getPageInfo().setWidth(imWidth);
pdfDocument.getPageSetup().setOrientation(PageFormat.LANDSCAPE);
Image image = new Image();
image.setImageStream(is);
pdfDocument.getPages().get_Item(1).getParagraphs().add(image);
page.getParagraphs().add(image);

Check out this code snippet

var pdfDocument = new Aspose.Pdf.Document();
var pdfPage = pdfDocument.Pages.Add();

pdfPage.PageInfo.IsLandscape = true;

var image = new Aspose.Pdf.Image();

byte[] array = System.IO.File.ReadAllBytes(myDir + "Image-116.jpg");
var mstream = new System.IO.MemoryStream(array);
image.ImageStream = mstream;
pdfPage.Paragraphs.Add(image);

pdfDocument.Save(myDir + "image-out.pdf");
