Examples

The example shows how to select a simple area of an image based on tone and color of any pixel using Magic Wand tool.

var imageFilePath = "input.png";
   using (RasterImage image = Image.Load(imageFilePath))
   {
       var maskSettings = new MagicWandSettings(120, 100) { Threshold = 150 };
       MagicWandTool.Select(image, maskSettings);
       MagicWandTool.Apply();
       image.Save(outputFilePath, new ImageOptions().PngOptions()
       {
           ColorType = PngColorType.TruecolorWithAlpha
       });
   }

The example shows how to select a complicated area of an image using Magic Wand tool and the ability to interact with masks (invert, union, substract).

var imageFilePath = "input.png";
   using (RasterImage image = (RasterImage)Image.Load(imageFilePath))
   {
       image.MagicWandTool.Select(new MagicWandSettings(845, 128));
       image.MagicWandTool.Union(new MagicWandSettings(416, 387));
       image.MagicWandTool.Invert();
       image.MagicWandTool.Subtract(new MagicWandSettings(1482, 346) { Threshold = 69 });
       image.MagicWandTool.Subtract(new RectangleMask(0, 0, 800, 150));
       image.MagicWandTool.Subtract(new RectangleMask(0, 380, 600, 220));
       image.MagicWandTool.Subtract(new RectangleMask(930, 520, 110, 40));
       image.MagicWandTool.Subtract(new RectangleMask(1370, 400, 120, 200));
       image.MagicWandTool.GetFeathered(new FeatheringSettings() { Size = 3 });
       image.MagicWandTool.Apply();
       image.Save(outputFilePath);
   }

Methods

Process(Rectangle, int[], Point, Point)

Processes the loaded pixels .

public void Process(
    Rectangle pixelsRectangle,
    int[] pixels,
    Point start,
    Point end)
{
}

Parameters

pixelsRectangle Rectangle

The pixels rectangle.

pixels int []

The 32-bit ARGB pixels.

start Point

The start pixels point. If not equal to (left,top) meaning that it is not full rectangle we have.

end Point

The end pixels point. If not equal to (right,bottom) meaning that it is not full rectangle we have.

Select(RasterImage, MagicWandSettings)

Creates a new Aspose.Imaging.MagicWand.ImageMasks.ImageBitMask based on Aspose.Imaging.MagicWand.MagicWandSettings and source Aspose.Imaging.RasterImage.

public static ImageBitMask Select(RasterImage source, MagicWandSettings settings)
{
}
In this case, no changes are required as the code is already formatted according to standard C# conventions. However, if there were inconsistencies in indentation, spacing, or readability, they would be corrected without altering the logic, variable names, or library-specific knowledge.

Parameters

source RasterImage

Raster image for the algorithm to work over.

settings MagicWandSettings

Settings of magic wand algorithm used in creating mask.

Returns

ImageBitMask

New Aspose.Imaging.MagicWand.ImageMasks.ImageBitMask.
