Hi!

I want to open, save, recompress and load again an image repeatedly in order to accumulate a visible loss in quality each time mouse is pressed.

That can only works if the image is closed, re-opened, edited and saved again.

Can anybody help please???

Here is a starting point I am unsatisfied with cause there is no noticeable alteration of the original image:

2. int openFile = 1; //name the source image as 1.jpg
3. int saveFile = 2;
4. int x, y=0;
5. PImage img;
6. 
   
7. void setup(){
8.   size(386, 600);//image size
9. }  
10. 
    
11. void draw(){
12. }
13. 
    
14. void mousePressed(){
15.   //can also paste the following code into draw for automation
16.   img = loadImage(openFile+".jpg");
17.   image(img, x, y, img.width, img.height);
18.   img.save(saveFile+".jpg");
19.   openFile = saveFile;
20.   saveFile = saveFile+1;
21. 
    
22.   print("opening"+openFile);
23.   print("   saving:");
24.   println(saveFile+"...done!");
25. 
    
26.   if (saveFile>1000){
27.     exit();
28.   }
29. }

 Thanks a lot!
