operating system?

the answer will differ wildly depending on whether you're using windows or a mac or linux.

I will use windows7 or 8

I cannot test on windows at the moment, but i think i've done this kind of things with something similiar to this:

String commandToRun = "mspaint /pt test.png";

void setup() {
   size(400, 400);
}

void draw() {
  // draw something
  ellipse(random(width), random(height), 20, 20);
}

void mousePressed() {
  // save the file
  saveFrame("test.png");

  // folder where your image-file is located
  File workingDir = new File(sketchPath(""));      

  try {
    // run command
    Process p = Runtime.getRuntime().exec(commandToRun, null, workingDir);
  }
  catch(IOException e) {
    println(e);
  }
}

edit: There was an error in the code, thanks to @GoToLoop for pointing it out.

Thanks Dear Benja, going to test it.

GoToLoop

@benja, don't access sketchPath, width & height before setup().
It won't work b/c they're not initialized yet! :|

roshani

every thing run except print.

sketch saves png file in sketch dir.

I have set dir address in Working Dir.

following error generate.

java.io.IOException: Cannot run program "mspaint" (in directory "sketch_151202a"): CreateProcess error=267, The directory name is invalid

My working folder is

D:\Myprocess\sketch_151202a

benja

Of course @GoToLoop is right, I will change the code above.
When i move the line with the working-directory to the mousePressed()-function it works for me on Windows7.
Do you have mspaint installed? You could check by writing "mspaint" in commandline.

roshani

Yes, it is installed.

Now working fine.
