        Code example:

        The following example shows how set the background color for EMF. It actually draws a rectangle of the background color before drawing all other objects.

        String baseFolder = "c:\\temp";

// This is a helper class which does all real work.
class Util {
    private void addBackgroundRectangleEmf(com.aspose.imaging.fileformats.emf.EmfImage image, com.aspose.imaging.Color color) {
        image.cacheData();
        com.aspose.imaging.fileformats.emf.MetaObjectList records = image.getRecords();

        if (records.size() < 1) {
            return;
        }

        //Set Rectangle
        com.aspose.imaging.fileformats.emf.emf.records.EmfRectangle rectangle = new com.aspose.imaging.fileformats.emf.emf.records.EmfRectangle();
        rectangle.setBox(image.getHeader().getEmfHeader().getBounds());

        //Set Brush
        com.aspose.imaging.fileformats.emf.emf.records.EmfCreateBrushIndirect brush = new com.aspose.imaging.fileformats.emf.emf.records.EmfCreateBrushIndirect();
        brush.setLogBrush(new com.aspose.imaging.fileformats.emf.emf.objects.EmfLogBrushEx());
        brush.getLogBrush().setArgb32ColorRef(color.toArgb());
        brush.setIhBrush(1);

        //Select brush
        com.aspose.imaging.fileformats.emf.emf.records.EmfSelectObject selectObject = new com.aspose.imaging.fileformats.emf.emf.records.EmfSelectObject();
        selectObject.setObjectHandle(1);

        //Remove brush
        com.aspose.imaging.fileformats.emf.emf.records.EmfDeleteObject deleteObject = new com.aspose.imaging.fileformats.emf.emf.records.EmfDeleteObject();
        deleteObject.setObjectHandle(1);

        //Add records
        records.insertItem(1, brush);
        records.insertItem(2, selectObject);
        records.insertItem(3, rectangle);
        records.insertItem(4, deleteObject);
    }
}

// Here is the main example
String[] files = new String[]{"image1.emf", "image2.wmf"};
for (String fileName : files) {
    String inputFile = baseFolder + fileName;
    String outputFile = baseFolder + "Background_" + fileName;
    com.aspose.imaging.fileformats.emf.MetaImage image = (com.aspose.imaging.fileformats.emf.MetaImage) com.aspose.imaging.Image.load(inputFile);
    try {
        new Util().addBackgroundRectangleEmf((com.aspose.imaging.fileformats.emf.EmfImage) image, com.aspose.imaging.Color.getBlue());
        image.save(outputFile);
    } finally {
        image.close();
    }
}
