hello all ;
I would like to do some fading  effect with processing…

I want to load a lot of images but one by one.

which means:

load image1.
Access pixel of image1
display image1.

and then replace this path with image 2 in a smooth transition of pixels fading.

load image2
acess pixel of image 2
SMOOTH TRANSITION FROM 1 TO 2
and then go for image2.

I would like a buffer of just one image, to "interpolate" in a smooth transition with the second image.

Because I have to deal with a lot of pictures, this should be so much simpler than load large array of pictures, and re-alocate them to picture1 which is the first to be displayed, then load picture 2, but make picture 1 disappear.

here's a little code which go to one picture to another one.

I hope I'm (a little bit) clear
thanks

1. PImage img1;
   PImage img2;
   int counter = 0;
   void setup()
   {
     size(400, 400);
     img1= loadImage("1.JPG");
     img2= loadImage("3.JPG");
   }
   
   void draw()
   {
     if (counter==0)
     {
   
   
   
       image(img1, 0, 0);
     }
     else {
   
   
       image(img2, 0, 0);
     }
   }
   
   void mousePressed()
   {
     if (counter==0)
     {
       counter =1;
     }
     else {
       counter = 0;
     }
     println(counter);
   }
