@ravikashyap,

I have worked with the sample file shared. An issue with ID IMAGINGJAVA-1442 has been created in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be notified once the issue will be fixed.

aspose.pdf.Image creates a blank PDF for the same above PNG file, with no exceptions thrown

Is this expected? If so, how can we check if the generated PDF is going to be blank?
If not, could you please open a different bug for this?

Document doc = new Document();
// Add a page to pages collection of document
Page page = doc.getPages().add();
// Load the source image file to Stream object
java.io.FileInputStream fs = new java.io.FileInputStream(imageFilename);
// Create an image object
Image image1 = new Image();
// Add the image into paragraphs collection of the section
page.getParagraphs().add(image1);
// Set the image file stream
image1.setImageStream(fs);

// Save resultant PDF file
doc.save(pdfFilename);

@ravikashyap,

Can you please use Aspose.Imaging for Java to convert PNG image to PDF and if there is still an issue than please share feedback with us. Also please visit this documentation link for source code.
