OutColor Property (original) (raw)
Summary
Gets or sets a color used to fill those pixels having an intensity value less than LowThreshold or greater than HighThreshold.
Syntax
C#
Objective-C

Python
@property (nonatomic, copy) LTRasterColor *outColor; Property Value
Color used to fill those pixels having an intensity value less than LowThreshold or greater than HighThreshold. This property has no effect if the Channel property is IntensityDetectCommandFlags.Master. If for example the Channel property is set to Red, then the red component of OutColor will be used to fill the pixels having a red component value less than LowThreshold or greater than HighThreshold.
Example
using Leadtools;
using Leadtools.Codecs;
using Leadtools.ImageProcessing.Color;
public void IntensityDetectCommandExample()
{
// Load an image
RasterCodecs codecs = new RasterCodecs();
codecs.ThrowExceptionsOnInvalidImages = true;
RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "dirty_barcode.jpg"));
// Prepare the command
IntensityDetectCommand command = new IntensityDetectCommand();
//Apply the filter.
command.LowThreshold = 128;
command.HighThreshold = 255;
command.InColor = new RasterColor(255, 255, 255);
command.OutColor = new RasterColor(0, 0, 0);
command.Channel = IntensityDetectCommandFlags.Master;
command.Run(image);
codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
