Take a still image from draw

R_Sørensen

Hi guys, i'm new here (i'm sorry in advance for my bad english). I want take a still image from my canvas while the animation running. I tried with copy() or get(), but these commands just copy every frame of draw(), constantly, while i would like to take a single picture and show it on the same sketch. How can i do it? Thanks in advance

You could use the mouse of keyboard to trigger a copy or get like this

void mouseClicked() {
  // Copy or get when the mouse is clicked
}

void keyTyped(){
  if(key == 's' {
    // Copy or get when the 's' key is typed (pressed & released)
  }
}

Demo: Capture image placed in the top right corner every 5 seconds approx. Use the mouse to draw something on the surface.

Kf

final int RAD=25;

PImage screenShot;

void setup() {
  size(600, 400);
  noStroke();
  background(0);
  captureImage();
}

void draw() {

  fill(255, 144);
  ellipse(mouseX, mouseY, RAD, RAD);

  //Next resets sketch every 5 secs approx.
  if (frameCount%150==0) {
    captureImage();
    background(0);   //Reset/clear current sketch 
  }

  fill(0, 250, 25);
  rect(width*0.78, height*0.08, screenShot.width*1.2, screenShot.height*1.2);
  image(screenShot, width*0.80, height*0.10);
}

void captureImage() {
  screenShot=get();  //Captures current screen
  screenShot.resize(int(width*0.18), 0);  //Keep width:height ratio
}
