public abstract class VectorImage
extends Image
implements IObjectWithSizeF

The vector image is the base class for all type of vector images.

See Also:

Image, IObjectWithSizeF

Code example:

The following example shows how to export a multipage vector image to another format in general way without referencing to a particular image type.

String dir = "C:\\aspose.imaging\\java\\misc\\ImagingReleaseQATester\\Tests\\testdata\\2548\\";
String inputFilePath = dir + "Multipage.cdr";
String outputFilePath = dir + "Multipage.cdr.tif";

com.aspose.imaging.ImageOptionsBase exportOptions = new com.aspose.imaging.imageoptions.TiffOptions(com.aspose.imaging.fileformats.tiff.enums.TiffExpectedFormat.Default);

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

    // Export only first two pages
    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);
}
