Method	Description
getMask()	Gets the set of graphic shapes that form mask.
setMask(GraphicsPath value)	Sets the set of graphic shapes that form mask.

Example: This example shows how to decompose a raster image into multiple images using image masking and a manual mask.

This example shows how to decompose a raster image into multiple images using image masking and a manual mask. Image masking is an image processing technique that is used to split the background from the foreground image objects.

String dir = "c:\\temp\\";

// Define a manual mask.
com.aspose.imaging.GraphicsPath manualMask = new com.aspose.imaging.GraphicsPath();
com.aspose.imaging.Figure figure = new com.aspose.imaging.Figure();
figure.addShape(new com.aspose.imaging.shapes.EllipseShape(new com.aspose.imaging.RectangleF(50, 50, 40, 40)));
figure.addShape(new com.aspose.imaging.shapes.RectangleShape(new com.aspose.imaging.RectangleF(10, 20, 50, 30)));
manualMask.addFigure(figure);

// Set the manual mask.
com.aspose.imaging.masking.options.ManualMaskingArgs args = new com.aspose.imaging.masking.options.ManualMaskingArgs();
args.setMask(manualMask);

com.aspose.imaging.RasterImage image = (com.aspose.imaging.RasterImage) com.aspose.imaging.Image.load(dir + "Blue hills.png");
try {
    com.aspose.imaging.masking.options.MaskingOptions maskingOptions = new com.aspose.imaging.masking.options.MaskingOptions();

    // Use manual clustering algorithm.
    maskingOptions.setMethod(com.aspose.imaging.masking.options.SegmentationMethod.Manual);

    // All shapes making up a mask will be combined into one.
    maskingOptions.setDecompose(false);
    maskingOptions.setArgs(args);

    // A maximum expected size of the TrueColor with Alpha PNG image.
    int estimatedMaxImageSize = image.getWidth() * image.getHeight() * 4;

    // Each cluster (segment) will be stored to a separate PNG file.
    com.aspose.imaging.imageoptions.PngOptions exportOptions = new com.aspose.imaging.imageoptions.PngOptions();

    exportOptions.setSource(new com.aspose.imaging.sources.StreamSource(new java.io.ByteArrayInputStream(new byte[estimatedMaxImageSize])));

    // The backgroung color will be orange.
    maskingOptions.setBackgroundReplacementColor(com.aspose.imaging.Color.getOrange());
    maskingOptions.setExportOptions(exportOptions);

    // The area of the source image that masking will be applied to.
    maskingOptions.setMaskingArea(new com.aspose.imaging.Rectangle(50, 50, 120, 120));

    // Create an instance of the ImageMasking class.
    com.aspose.imaging.masking.ImageMasking masking = new com.aspose.imaging.masking.ImageMasking(image);

    // Divide the source image into several clusters (segments).
    com.aspose.imaging.masking.result.MaskingResult maskingResults = masking.decompose(maskingOptions);

    try
    {
        // Obtain images from masking result and save them to PNG.
        for (int i = 0; i < maskingResults.getLength(); i++) {
            String outputFileName = String.format("Blue hills.Segment%s.png", maskingResults.get_Item(i).getObjectNumber());
            Image resultImage = maskingResults.get_Item(i).getImage();
            try {
