Java: Convert SVG to PDF

SVG files are vector-based graphics that can be scaled and resized without losing quality. While they can be very useful in certain scenarios, there may still be times when you need to convert them to PDFs for further processing, sharing, distributing, printing, or archiving. In this article, you will learn how to programmatically convert SVG images to PDF files using Spire.PDF for Java.

Convert SVG to PDF in Java

Spire.PDF for Java offers the PdfDocument.loadFromSvg() method to load an SVG file directly, and you can then convert it to a PDF file through the PdfDocument.saveToFile() method. The following are the detailed steps.

• Create a PdfDocument instance.
• Load a sample SVG file using PdfDocument.loadFromSvg() method.
• Convert the SVG file to PDF using PdfDocument.saveToFile(String filename, FileFormat.PDF) method.

import com.spire.pdf.FileFormat;
import com.spire.pdf.PdfDocument;

public class SVGToPDF {
    public static void main(String[] args) {
        //Create a PdfDocument instance
        PdfDocument pdf = new PdfDocument();

        //Load a sample SVG file
        pdf.loadFromSvg("sample.svg");

        //Save as PDF file
        pdf.saveToFile("SVGToPDF.pdf", FileFormat.PDF);
    }
}

Add SVG Images to PDF in Java

In addition to converting SVG to PDF, Spire.PDF for Java also supports adding SVG images to PDF files. During the process, you are allowed to set the position and size of the SVG image. The following are the detailed steps.

• Create a PdfDocument instance and load an SVG file using PdfDocument.loadFromSvg() method.
• Create a template based on the content of the SVG file using PdfDocument.getPages().get().createTemplate() method.
• Create another PdfDocument object and load a PDF file using PdfDocument.loadFromFile() method.
• Get a specified page in the PDF file using PdfDocument.getPages().get() method.
• Draw the template with a custom size at a specified location on the PDF page using PdfPageBase.getCanvas().drawTemplate() method.
• Save the result PDF file using PdfDocument.saveToFile() method.

import com.spire.pdf.FileFormat;
import com.spire.pdf.PdfDocument;
import com.spire.pdf.graphics.PdfTemplate;

import java.awt.*;
import java.awt.geom.Point2D;

public class AddSVGImagetoPDF {
    public static void main(String[] args) {
        //Create a PdfDocument instance
        PdfDocument doc1 = new PdfDocument();

        //Load an SVG file
        doc1.loadFromSvg("Image.svg");

        //Create a template based on the content of the SVG file
        PdfTemplate template = doc1.getPages().get(0).createTemplate();

        //Create another PdfDocument instance
        PdfDocument doc2 = new PdfDocument();

        //Load a PDF file
        doc2.loadFromFile("Intro.pdf");

        //Draw the template with a custom size at a specified location in the PDF file
        doc2.getPages().get(0).getCanvas().drawTemplate(template, new Point2D.Float(100,200), new Dimension(400,280) );

        //Save the result file
        doc2.saveToFile("AddSVGtoPDF.pdf", FileFormat.PDF);
        doc1.close();
        doc2.close();
    }
}
