Hello,

Is it possible to change the color of the line showing the edges to red (or some other color) from the default white color? I am using leadtools 17 and .Net classes.

EdgeDetectEffectCommand command = new EdgeDetectEffectCommand();
            command.Level = 70;
            command.Threshold = 0;
            command.Type = EdgeDetectEffectCommandType.Smooth;
            command.Run(image);

Thanks....

To generate the color you're desiring you would need to use some form of color replacement.
 
Other options would involve using the different CombineCommands with specific flags to use the EdgeDetectEffectCommand results as a mask with a colored image or only specific color channels being used. Perhaps the below link will assist you:
