using Leadtools; using Leadtools.Codecs; using Leadtools.ImageProcessing.Color; public void ColorThresholdCommandExample() { // Load an image RasterCodecs codecs = new RasterCodecs(); codecs.ThrowExceptionsOnInvalidImages = true; RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image1.jpg")); // Prepare the command ColorThresholdCommandComponent[] Components = new ColorThresholdCommandComponent[3]; Components[0] = new ColorThresholdCommandComponent(); Components[0].MinimumRange = 128; Components[0].MaximumRange = 255; Components[0].Flags = 0; Components[1] = new ColorThresholdCommandComponent(); Components[1].MinimumRange = 128; Components[1].MaximumRange = 255; Components[1].Flags = 0; Components[2] = new ColorThresholdCommandComponent(); Components[2].MinimumRange = 128; Components[2].MaximumRange = 255; Components[2].Flags = 0; ColorThresholdCommand command = new ColorThresholdCommand(ColorThresholdCommandType.Rgb, Components); //Apply color Threshold effect on the image. 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"; }
