Magic Wand tool Image Filter

Magic Wand tool

         By using the MagicWandTool class from the Aspose.Imaging library, you can select a color area on a loaded image by specifying an arbitrary point within that area using the MagicWandSettings parameter. The Magic Wand tool will generate a mask based on color and tone comparisons with the surrounding pixels. You can adjust the mask's coverage by setting the Threshold parameter. A higher threshold will result in a larger mask area, potentially including unwanted parts of the image. Conversely, reducing the threshold allows you to create a mask that targets a more specific color area.

         Once you've created a mask, you can add additional areas to it using the `Union` method, subtract regions from the existing mask, invert it, and smooth the edges using the `GetFeathered` method. Finally, you can apply the mask to the image and save the resulting image to disk.
