PDFBox Error When Converting to BufferedImage: NoClassDefFoundError: org/apache/fontbox/FontBoxFont

Question

I'm trying to convert a PDF doc to .png files using PDFBox. I followed this answer to get an idea of what dependencies were needed and to give me a starting point. When I try to loop through the pages and create the BufferedImage I receive a NoClassDefFoundError error. It's looking for org/apache/fontbox/FontBoxFont but through some extensive Googling I've not found a thing about FontBoxFont. Is this a separate jar that needs to be included? What is causing this error? The following .jar's are included in the project:

pdfbox-2.0.2.jar
levigo-jbig2-imageio-1.6.5.jar
pdfbox-tools-2.0.2.jar
jai-imageio-core-1.3.1.jar
commons-logging-1.2.jar

Here is the main method:

public static void main(String[] args) {

    String sourceDir = "C:/Dev/Workspace/PdfToPng/Stocks.pdf";
    String destinationDir = "C:/Dev/Workspace/PdfToPng/pages/";

    try {
        PDDocument document = PDDocument.load(new File(sourceDir));
        PDFRenderer pdfRenderer = new PDFRenderer(document);
        for(int page = 0; page < document.getNumberOfPages(); ++page) {
            BufferedImage bim = pdfRenderer.renderImageWithDPI(page, 300, ImageType.RGB);
            ImageIOUtil.writeImage(bim, destinationDir + (page+1) + ".png", 300);
        }
        document.close();
    } catch(Exception e) {
        System.out.println(e.getStackTrace());
    }
}

The error is thrown on BufferedImage bim = pdfRenderer.renderImageWithDPI(page, 300, ImageType.RGB);

Answer 1

Obviously you need to add Apache FontBox 2.0.2 to your classpath, you can get it from mvnrepository

@Shaggy, when you download the bundle from - pdfbox.apache.org/download.cgi#20x - pdfbox-2.0.13-src.zip - you will get all jars in that bundle, as Nick said above. – Cough
