Convert SVG into PDF using Java REST API

This short tutorial guides on how to convert SVG into PDF using Java REST API. It will teach you the process of developing an SVG to PDF converter using Java Low Code API with a Java-based Cloud SDK. You will learn the workings of the API and download the converted file from the Cloud storage.

Prerequisite

Steps to Change SVG to PDF using Java REST API

  1. Create an instance of the PdfApi object with client ID and secret for changing SVG to PDF
  2. Define the name of the source SVG file name for use in Cloud storage
  3. Read all bytes from the source SVG and create a MemoryStream object
  4. Invoke the UploadFile() method to upload the memory stream to the Cloud storage
  5. Call the GetSvgInStorageToPdf() method to transform the SVG file in the Cloud storage to a PDF file
  6. Parse the API response and retrieve the memory stream containing the PDF file

These steps summarize the process of changing SVG to PDF using Java REST Interface. Read all the bytes of the SVG file into a memory stream, upload it to a Cloud storage, and call the GetSvgInStorageToPdf() method to transform the SVG file to PDF. Finally, retrieve the resultant PDF file generated from the SVG using the API response and save it on the disk.

This code has demonstrated the transformation of the file format from SVG to PDF using Java RESTful Service. The memory stream can be generated from the file on the disk or retrieved from a database or network. You can further modify the newly created PDF by uploading it to the Cloud storage and performing desired operations as per the requirement.
