Example

Run the DynamicBinaryCommand on an image.

using Leadtools; using Leadtools.Codecs; using Leadtools.ImageProcessing.Color; public void DynamicBinaryCommandExample() { // Load an image RasterCodecs codecs = new RasterCodecs(); codecs.ThrowExceptionsOnInvalidImages = true; RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg")); // Prepare the command DynamicBinaryCommand command = new DynamicBinaryCommand(); command.Dimension = 8; command.LocalContrast = 16; // convert it into a black and white image without changing its bits per pixel. command.Run(image); codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); } static class LEAD_VARS { public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; }
