The Count 2 Tiff Tag in Java

To set Tiff tags in Java, you need to specify the tag’s code, name, and value, as explained here.

But certain tags hold a peculiarity of having a “Count 2” attribute, which means that one tag can receive two values:

Setting these tags in Java requires this code in addition to PDFBox codes.

private static IIOMetadataNode createShortField(int tiffTagNumber, String name, int val1, int val2) {
    IIOMetadataNode field = new IIOMetadataNode("TIFFField");
    field.setAttribute("number", Integer.toString(tiffTagNumber));
    field.setAttribute("name", name);
    IIOMetadataNode arrayNode = new IIOMetadataNode("TIFFShorts");
    field.appendChild(arrayNode);
    IIOMetadataNode valueNode1 = new IIOMetadataNode("TIFFShort");
    arrayNode.appendChild(valueNode1);
    valueNode1.setAttribute("value", Integer.toString(val1));
    IIOMetadataNode valueNode2 = new IIOMetadataNode("TIFFShort");
    arrayNode.appendChild(valueNode2);
    valueNode2.setAttribute("value", Integer.toString(val2));
    return field;
}
