hey! i need to make a kind of a snow effect and so i thought i could blur some ellipses but the problem is i don't know how to only apply blur once to an ellipse... it keeps adding to the whole frame ( or stage or something) and the ellipses keep getting more blurry as other ellipses are blured on top

i thought i make something like only applying if the frameCount is  less or equal than 1, and reset the frameCount everytime i draw an ellipse but it doesnt work...

here is my code

Code:

 import processing.pdf.*;
  Bolas b1 = new Bolas();
  PImage img;
void setup(){
// size(640,480,PDF, "postal.pdf");
 size(640,480,P2D);

 smooth();
 background(255);
img = loadImage("arvore.jpg");



  

}


void draw(){
  



   for(int i = 0; i < 10; i++) {
   // noStroke();
  int x = (int)random(width);
  int y = (int)random(height);
  color col = img.get(x,y);
  fill(col);
  float prop = random(20);
    float prop2 =prop;
  //ellipseMode(CENTER);
 noStroke();
 pushMatrix();

  b1.desenhar(x,y,prop,prop);
popMatrix();
  }
  
  

}

class Bolas{

  
  Bolas(){
	frameCount = 0;
  }
  
  void desenhar(int x, int y , float prop, float prop2){
    ellipse(x,y,prop,prop);
    if(frameCount<2){
	filter(BLUR,5);
    }
  }
  } 

unfortunatly it's not a mistake. My purpose is to have some snow draw a christmas tree by taking the color from an image , so I have to keep the frames there otherwise if i put a background() it would disapear all the drawing it did til that moment. What i want is for the snow particle to be blury but always at the same level, not adding blur.

Is it better if i use some kind of image? but if i use an image it won't be coloured by the image...

thank you, i'm going to try that!
