I'm trying to add image to new word document using docx4j. I've taken this code from online and modified it for my program, however I receive a strange error and I'm not sure what is causing it or how to debug it...

Here's my code

Code: Select all

private static void test()
{
    WordprocessingMLPackage wordMLPackage = null;
    try {
        wordMLPackage = WordprocessingMLPackage.createPackage();
    } catch (InvalidFormatException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
        javax.swing.JOptionPane.showMessageDialog(panel, "Cannnot create package.");
    }
    wordMLPackage.getMainDocumentPart().addStyledParagraphOfText("Title", "Hello Word! \n\t" + "Try This!");

    byte[] bytes = null;
    try {
        bytes = convertImageToByteArray();
    } catch (FileNotFoundException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
        javax.swing.JOptionPane.showMessageDialog(panel, "Image file not found.");
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
        javax.swing.JOptionPane.showMessageDialog(panel, "Image file exception: " + e1.toString());
    }
    try {
        addImageToPackage(wordMLPackage, bytes);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        javax.swing.JOptionPane.showMessageDialog(panel, "Cannot add image to package: " + e.toString());
    }

    try {
        wordMLPackage.save(new java.io.File("HelloWord7.docx"));
    } catch (Docx4JException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        javax.swing.JOptionPane.showMessageDialog(panel, "Cannot save image to file.");
    }
}

private static void addImageToPackage(WordprocessingMLPackage wordMLPackage,
        byte[] bytes) throws Exception {
    BinaryPartAbstractImage imagePart =
            BinaryPartAbstractImage.createImagePart(wordMLPackage, bytes);

    int docPrId = 1;
    int cNvPrId = 2;
    Inline inline = imagePart.createImageInline("Filename hint",
            "Alternative text", docPrId, cNvPrId, false);

    P paragraph = addInlineImageToParagraph(inline);
    wordMLPackage.getMainDocumentPart().addObject(paragraph);
}

private static P addInlineImageToParagraph(Inline inline) {
    // Now add the in-line image to a paragraph
    ObjectFactory factory = new ObjectFactory();
    P paragraph = factory.createP();
    R run = factory.createR();
    paragraph.getContent().add(run);
    Drawing drawing = (Drawing) factory.createDrawing();
    run.getContent().add(drawing);
    ((org.docx4j.wml.Drawing) drawing).getAnchorOrInline().add(inline);
    return paragraph;
}


private static byte[] convertImageToByteArray() throws IOException {
    // get DataBufferBytes from Raster
    WritableRaster raster = logo.getRaster();
    DataBufferByte data = (DataBufferByte)raster.getDataBuffer();

    return (data.getData());
}


I'm getting the following error on line

Code: Select all

BinaryPartAbstractImage imagePart =
            BinaryPartAbstractImage.createImagePart(wordMLPackage, bytes);


Error returned is: Docx4JException: Error checking image format.

Here's is how 'logo' is loaded,

Code: Select all

try {
        BufferedImage logo = ImageIO.read(getClass().getResourceAsStream("/logo.png"));
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        javax.swing.JOptionPane.showMessageDialog(panel, "Cannot load logo for word doc");
    }


Any help is appreciated, thanks

I've tried using different images, jpg, png etc but still the same result ....


Any help??

Additional info ....

I run the application as runnable jar and receive the error above. However, when I run the application inside eclipse the program gets stuck instead of giving the error.

I've modified the code a bit, and here's how I run it from eclipse ...

Code: Select all

private static void test() throws Exception
{
    File file = new File("logo.png" );
    if (!file.canRead())
        javax.swing.JOptionPane.showMessageDialog(panel, "Cannot read file");
    if (!file.exists())
        javax.swing.JOptionPane.showMessageDialog(panel, "File does not exist");
    javax.swing.JOptionPane.showMessageDialog(panel, file.getAbsolutePath());

    String filenameHint = null;
    String altText = null;

    int id1 = 0;
    int id2 = 1;

    P p = newImage(wordMLPackage, file, filenameHint, altText, id1, id2);

    wordMLPackage.getMainDocumentPart().addObject(p);
    wordMLPackage.save(new File("Example.docx"));
}

public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            try {
                wordMLPackage = WordprocessingMLPackage.createPackage();
            } catch (InvalidFormatException e2) {
                // TODO Auto-generated catch block
                e2.printStackTrace();
                javax.swing.JOptionPane.showMessageDialog(panel, "Could not create wordMLPackage: " + e2.toString());
            }
            new Calculator().setVisible(true);
        }
    });
}

Please someone pinpoint a way to debug or an error in my code ...

Didn't include the entire code block in last post ..

Code: Select all

public static P newImage(WordprocessingMLPackage wordMLPackage, File file,
        String filenameHint, String altText, int id1, int id2) throws Exception {
    BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordMLPackage, file);
    //.createImagePart(wordMLPackage, bytes);
    javax.swing.JOptionPane.showMessageDialog(panel, "Created image part");
    Inline inline = imagePart.createImageInline(filenameHint, altText, id1, id2, false);

    ObjectFactory factory = new ObjectFactory();

    P  p = factory.createP();
    R  run = factory.createR();

    p.getContent().add(run);       
    Drawing drawing = (Drawing) factory.createDrawing();     
    run.getContent().add(drawing);       
    ((org.docx4j.wml.Drawing) drawing).getAnchorOrInline().add(inline);

    return p;
}

private static void test() throws Exception
{
    File file = new File("logo.png" );
    if (!file.canRead())
        javax.swing.JOptionPane.showMessageDialog(panel, "Cannot read file");
    if (!file.exists())
        javax.swing.JOptionPane.showMessageDialog(panel, "File does not exist");
    javax.swing.JOptionPane.showMessageDialog(panel, file.getAbsolutePath());

    String filenameHint = null;
    String altText = null;

    int id1 = 0;
    int id2 = 1;

    P p = newImage(wordMLPackage, file, filenameHint, altText, id1, id2);

    wordMLPackage.getMainDocumentPart().addObject(p);
    wordMLPackage.save(new File("Example.docx"));
}

public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            try {
                wordMLPackage = WordprocessingMLPackage.createPackage();
            } catch (InvalidFormatException e2) {
                // TODO Auto-generated catch block
                e2.printStackTrace();
                javax.swing.JOptionPane.showMessageDialog(panel, "Could not create wordMLPackage: " + e2.toString());
            }
            new Calculator().setVisible(true);
        }
    });
}
