Hi Everyone! I am currenly learning Processing for the first time. I have gone through a few tutorials and read alot of notes. I recently learned the ability to pixelate an image. I have modified the code to make each time i click, the pixelation increases by 10. I was wondering if it is possible for it to reach 155 pixels wide, then when i continue to click, the pixelation will decrease until it reaches 10 pixels again. The outcome i am looking for will be continual clicking blurring then unblurring the picture incrimentally. I have provided the code i have already below.

Thanks for any help anyone can provide.

PImage leftovers;
int detail = 5;
int undetail = 5;

void setup(){
 size (400,268);
 leftovers=loadImage("blogPhoto023.jpg");
 image(leftovers, 0, 0);
}

void draw(){
 ;
}

void mouseClicked(){
 for ( int i=0; i<width; i+=detail ){
   for ( int j=0; j<height; j+=undetail){
     color c=leftovers.get(i,j);
     fill(c);
     rect(i, j, detail, undetail);
   }
 }
 if (detail < 155){
   detail += 10;
 }
 if (undetail < 155){
   undetail += 10;
}
