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 = (RasterImage)Image.Load(inputFilePath))
{
// Create a new mask using magic wand tool based on tone and color of pixel (120, 100) with custom threshold equal to 150
MagicWandTool
.Select(image, new MagicWandSettings(120, 100) { Threshold = 150 })
// Apply mask to the image
.Apply();
// Save image with forced transparency color type option
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(inputFilePath))
{
// Create a new mask using magic wand tool based on tone and color of pixel (845, 128)
MagicWandTool.Select(image, new MagicWandSettings(845, 128))
// Union the existing mask with the specified one created by magic wand tool
.Union(new MagicWandSettings(416, 387))
// Invert the existing mask
.Invert()
// Subtract the specified mask created by magic wand tool with specified threshold from the existing one
.Subtract(new MagicWandSettings(1482, 346) { Threshold = 69 })
// Subtract four specified rectangle masks from the existing mask one by one
.Subtract(new RectangleMask(0, 0, 800, 150))
.Subtract(new RectangleMask(0, 380, 600, 220))
.Subtract(new RectangleMask(930, 520, 110, 40))
.Subtract(new RectangleMask(1370, 400, 120, 200))
// Feather mask with specified settings
.GetFeathered(new FeatheringSettings() { Size = 3 })
// Apply mask to the image
.Apply();
// Save image
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)Parameters
source RasterImage
Raster image for the algorithm to work over.
settings MagicWandSettings
Settings of magic wand algorithm used in creating mask.
Returns
New Aspose.Imaging.MagicWand.ImageMasks.ImageBitMask.
