Example: The following example shows how to convert a multipage vector image to JPEG 2000 format in general way without referencing to a particular image type.

String dir = "C:\\aspose.imaging\\net\\misc\\ImagingReleaseQATester\\Tests\\testdata\\2548";
String inputFilePath = (dir + "Multipage.cdr");
String outputFilePath = (dir + "Multipage.cdr.j2k");

com.aspose.imaging.ImageOptionsBase exportOptions = new com.aspose.imaging.imageoptions.Jpeg2000Options();

try (com.aspose.imaging.Image image = com.aspose.imaging.Image.load(inputFilePath))
{
    exportOptions.setMultiPageOptions(null);

    // Export only first two pages. In fact, only one page will be rasterized because JPEG 2000 is not a multi-page format.
    com.aspose.imaging.IMultipageImage multipageImage = (image instanceof com.aspose.imaging.IMultipageImage) ? (com.aspose.imaging.IMultipageImage) image : null;
    if (multipageImage != null && (multipageImage.getPages() != null && multipageImage.getPageCount() > 2))
    {
        exportOptions.setMultiPageOptions(new com.aspose.imaging.imageoptions.MultiPageOptions(new com.aspose.imaging.IntRange(0, 2)));
    }

    if (image instanceof com.aspose.imaging.VectorImage)
    {
        com.aspose.imaging.imageoptions.VectorRasterizationOptions defaultOptions = (com.aspose.imaging.imageoptions.VectorRasterizationOptions) image.getDefaultOptions(new Object[]{Color.getWhite(), image.getWidth(), image.getHeight()});
        exportOptions.setVectorRasterizationOptions(defaultOptions);
        defaultOptions.setTextRenderingHint(com.aspose.imaging.TextRenderingHint.SingleBitPerPixel);
        defaultOptions.setSmoothingMode(com.aspose.imaging.SmoothingMode.None);
    }

    image.save(outputFilePath, exportOptions);
}
