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
• Add SVG Images to PDF in Java

Install Spire.PDF for Java

First of all, you're required to add the Spire.Pdf.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

<repositories>
    <repository>
        <id>com.e-iceblue</id>
        <name>e-iceblue</name>
        <url>https://repo.e-iceblue.com/nexus/content/groups/public/</url>

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();
    }
}

This article demonstrates how to add shadow effects to shapes in PowerPoint by using Spire.Presentation for Java. In addition to the PresetShadowEffect shown in this article, you can also add InnerShadowEffect, OuterShadowEffect and SoftEdgeEffect, etc.

import com.spire.presentation.*;
import com.spire.presentation.drawing.*;
import java.awt.*;
import java.awt.geom.Rectangle2D;

public class setShadowEffect {
    public static void main(String[] args) throws Exception {

        //Create a Presentation instance
        Presentation ppt = new Presentation();

        //Get the first slide
        ISlide slide = ppt.getSlides().get(0);

        //Add a shape to the slide.
        Rectangle2D rect = new Rectangle2D.Float(120, 100, 150, 300);
        IAutoShape shape = slide.getShapes().appendShape(ShapeType.RECTANGLE, rect);

        //Fill the shape with a picture
        shape.getFill().setFillType(FillFormatType.PICTURE);
        shape.getFill().getPictureFill().getPicture().setUrl("https://cdn.e-iceblue.com/C:\\Users\\Administrator\\Desktop\\img.png");
        shape.getLine().setFillType(FillFormatType.NONE);
        shape.getFill().getPictureFill().setFillType(PictureFillType.STRETCH);

        //Set shadow effect
        PresetShadow presetShadow = new PresetShadow();
        presetShadow.setPreset(PresetShadowValue.BACK_RIGHT_PERSPECTIVE);
        presetShadow.getColorFormat().setColor(Color.lightGray);

        //Apply the shadow effect to shape
        shape.getEffectDag().setPresetShadowEffect(presetShadow);

        //Save the document
        ppt.saveToFile("output/ShapeShadow.pptx", FileFormat.PPTX_2013);
    }
}

This article demonstrates how to detect merged cells in an Excel worksheet and unmerge the merged cells using Spire.XLS for Java.

The input Excel file:

import com.spire.xls.CellRange;
import com.spire.xls.ExcelVersion;
import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;

public class DetectMergedCells {
    public static void main(String[] args) throws Exception {

        workbook.loadFromFile( "Input.xlsx");

        //Get the first worksheet
        Worksheet sheet = workbook.getWorksheets().get(0);

        //Get the merged cell ranges in the first worksheet and put them into a CellRange array
        CellRange[] range = sheet.getMergedCells();

        //Traverse through the array and unmerge the merged cells
        for(CellRange cell : range){
            cell.unMerge();
        }
        
        //Save the result file
        workbook.saveToFile("DetectMergedCells.xlsx", ExcelVersion.Version2013);
    }
