Steps to Convert PDF to XPS Document using Java REST Interface

  1. Create the PdfApi object to change PDF to XPS
  2. Read the source PDF file contents into a byte array
  3. Convert the byte array to a MemoryStream for uploading
  4. Upload the MemoryStream to the Cloud storage containing a PDF file
  5. Call the GetPdfInStorageToXps() to transform PDF to XPS
  6. Parse the API response and fetch the XPS contents for saving on the disk

The above steps describe the process of converting the PDF of XPS using Java RESTful Service. Load the source PDF file into a byte array and create a memory stream for loading it to the Could storage. Finally, call the GetPdfInStorageToXps() method to change the online PDF file to XPS and return the converted XPS stream.

// Convert PDF to XPS
InputStream xpsStream = pdfApi.getPdfInStorageToXps(documentName, null, null);
// Save the result locally
try (FileOutputStream outputStream = new FileOutputStream(outputFileName)) {
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = xpsStream.read(buffer)) != -1) {
outputStream.write(buffer, 0, bytesRead);
}
}
System.out.println("PDF successfully converted to XPS and saved as: " + outputFileName);
} catch (Exception e) {
e.printStackTrace();
}
}
}

This code demonstrates the conversion of PDF to XPS file using Java REST API. You may upload multiple PDF files to the Cloud storage and call the GetPdfInStorageToXps() method individually for each PDF and convert it to an XPS file. You may also customize the uploaded PDF file before converting it to the XPS format if required.

This guide has taught us the development of a PDF to XPS file converter using Java Low Code API. To transform a PCL file to PDF, refer to the article Convert PCL file to PDF using Java REST API.
