Class MagicWandTool

java.lang.Object

com.aspose.imaging.magicwand.MagicWandTool

All Implemented Interfaces:

IPartialArgb32PixelLoader

public class MagicWandTool
extends Object
implements IPartialArgb32PixelLoader

The class for magic wand algorithm main logic.

Code example:

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

String imageFilePath = "input.png";
String outputFilePath = "masked.png";
try (RasterImage image = (RasterImage)Image.load(imageFilePath))
{
    // 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) {{ setThreshold(150); }})
            // Apply mask to the image
            .apply();

    // Save image with forced transparency color type option
    image.save(outputFilePath, new PngOptions()
    {{
        setColorType(PngColorType.TruecolorWithAlpha);
    }});
}

Method Detail

select

public static ImageBitMask select(RasterImage source,
                                  MagicWandSettings settings)

Creates a new ImageBitMask based on MagicWandSettings and source RasterImage.

Parameters:

source - Raster image for the algorithm to work over.

settings - Settings of magic wand algorithm used in creating mask.

Returns:

New ImageBitMask.

process

public final void process(Rectangle pixelsRectangle,
                          int[] pixels,
                          Point start,
                          Point end)

Processes the loaded pixels .

Specified by:

process in interface IPartialArgb32PixelLoader

Parameters:

pixelsRectangle - The pixels rectangle.

pixels - The 32-bit ARGB pixels.

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

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