c# - How to Change the color of each pixel in a image by using Magick.Net -

i'm new magick.net. tried change color of each pixel in image there's no change in new image. here's code. tell me what's going on? lot.

  using system;   using system.collections.generic;   using system.linq;   using system.text;   using system.threading.tasks;   using imagemagick;   namespace magicktutor   {    class program      {        static void main(string[] args)         {           magickimage image = new magickimage();           image.read("c:\\.....\\test1.png");           foreach (pixel p in image.getwritablepixels()) {               p.setchannel(0, 65535);           }           image.write("c:\\.....\\test2.png");         }       }   } 

you should call write method of writablepixelcollection class returned image.getwritablepixels() make sure pixels written image.

you doing in different way:

using (magickimage image = new magickimage()) {   image.read(@"c:\.....\test1.png");   image.evaluate(channels.red, evaluateoperator.set, quantum.max);   image.write(@"c:\.....\test2.png"); }
