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.
<br><br>
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.<br><br>Perhaps the below link will assist you:<br>
