Hi,
I'm new here, so maybe this has been already explained before, but i didn't found it.
Sorry if it's the case. If it's not, could anyone explain me why it's not working ?


 I tried to export my first processing stuff, as an applet, but it didn't work.
I couldn't read it on any browser.

I also exported it as an application (I'm working on mac).
It worked since I press Esc instead of closing the window (clicking or with the shortcut).
When I close it normaly (clicking for example). it corrupting my png file, so when i'm reopening it,
I got a blank new one (instead of having it has it was when I closed it)

I think there is something wrong about the way I'm saving it, or the way i'm lauching the png file.

If anyone could give me a hand on this it would really help me.

Thanks, and sorry again if it seems a really basic question
(also apologize for my engl, not my native language)

This is my code so far.

1. PImage b;
   
   void setup () {
       size (1000, 1000);
       cursor(CROSS);
       b = loadImage("draw.png");
       tint(255, 70);
       image(b, 0, 0);
         
   
   }
   
   void draw () {
       if (mousePressed) {
           fill (random(0, 50));
           rect (mouseX, mouseY, random(1, 20), random(1, 20));
          
       } else {
         fill (255, 0);
         noStroke ();
         rect (mouseX, mouseY, random(1, 100), random(1, 100));
         save("draw.png");
       }
      
   }
