Steps for XHTML to PDF Converter using Java Low Code API

  1. Add Aspose.HTML.Cloud.Sdk and Aspose.HTML.Cloud.Sdk.Conversion to your application for accessing HTML Cloud API classes and conversion features
  2. Create an instance of HtmlApi by providing your Client ID and Client Secret for authentication with Aspose Cloud
  3. Retrieve the ConvertApi object from the initialized HtmlApi to perform document conversions
  4. Instantiate a PDFConversionOptions object to define output parameters for the PDF file
  5. Set the PDF page height to 8 inches and width to 11 inches (landscape format)
  6. Specify all four margins—top, bottom, left, and right—as 1 inch each
  7. Call ConvertAsync() on the convertApi to convert the XHTML file into a PDF

These steps explain how to change an XHTML document to PDF using Java API. To convert your XHTML file into a PDF, first connect to Aspose Cloud by adding the SDK, authenticating with your Client ID and Secret, and then accessing the conversion API. After that, set up your PDF options such as page size and margins, and run ConvertAsync() to generate the final PDF.
