Examples
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.```csharp [C#]
string dir = "c:\\temp\\";
// Define a manual mask.
Aspose.Imaging.GraphicsPath manualMask = new Aspose.Imaging.GraphicsPath();
Aspose.Imaging.Figure figure = new Aspose.Imaging.Figure();
figure.AddShape(new Aspose.Imaging.Shapes.EllipseShape(new RectangleF(50, 50, 40, 40)));
figure.AddShape(new Aspose.Imaging.Shapes.RectangleShape(new RectangleF(10, 20, 50, 30)));
manualMask.AddFigure(figure);
// Each cluster (segment) will be stored to a separate PNG file.
Aspose.Imaging.ImageOptions.PngOptions exportOptions = new Aspose.Imaging.ImageOptions.PngOptions();
exportOptions.ColorType = Aspose.Imaging.FileFormats.Png.PngColorType.TruecolorWithAlpha;
exportOptions.Source = new Aspose.Imaging.Sources.StreamSource(new System.IO.MemoryStream());
// Set the manual mask.
Aspose.Imaging.Masking.Options.ManualMaskingArgs args = new Aspose.Imaging.Masking.Options.ManualMaskingArgs();
args.Mask = manualMask;
using (RasterImage image = (RasterImage)Image.Load(dir + "Blue hills.png"))
{
Aspose.Imaging.Masking.Options.MaskingOptions maskingOptions = new Aspose.Imaging.Masking.Options.MaskingOptions();
// Use manual clustering algorithm.
maskingOptions.Method = Masking.Options.SegmentationMethod.Manual;
// All shapes making up a mask will be combined into one.
maskingOptions.Decompose = false;
maskingOptions.Args = args;
// The backgroung color will be orange.
maskingOptions.BackgroundReplacementColor = Aspose.Imaging.Color.Orange;
maskingOptions.ExportOptions = exportOptions;
// The area of the source image that masking will be applied to.
maskingOptions.MaskingArea = new Rectangle(50, 50, 120, 120);
// Create an instance of the ImageMasking class.
Aspose.Imaging.Masking.ImageMasking masking = new Aspose.Imaging.Masking.ImageMasking(image);
// Divide the source image into several clusters (segments).
using (Aspose.Imaging.Masking.Result.MaskingResult maskingResult = masking.Decompose(maskingOptions))
{
// Obtain images from masking result and save them to PNG.
for (int i = 0; i < maskingResult.Length; i++)
{
string outputFileName = string.Format("Blue hills.Segment{0}.png", maskingResult[i].ObjectNumber);
using (Aspose.Imaging.Image resultImage = maskingResult[i].GetImage())
{
