Project-09-Portrait

I used lines that are randomly horizontal and vertical, and stroke width and lengths that progressively get smaller as the frames approach 10000, increasing the resolution of the portrait. At the end, the text ‘fin’ is displayed to conclude the drawing of the portrait.

let picture;
function preload() {
  picture = loadImage('https://i.imgur.com/3hKjmTL.jpg');
}

function setup() {
  createCanvas(480, 480);
  imageMode(CENTER);
  textAlign(CENTER);
  noStroke();
  background(0);
  picture.loadPixels();
  frameRate(60);
}

function draw() {
  //chooses random pixel coordinates
  let x = floor(random(picture.width));
  let y = floor(random(picture.height));
  //gets the pixel color
  let pixelcolor = picture.get(x,y);
  //sets whether the line is randomly vertical or horizontal
  let verticality=[true,false];
  let horiz=random(verticality);
  stroke(pixelcolor);
  //sets the stroke weight in relation to the frame count
  strokeWeight(map(10000-frameCount,10000,0,20,0));
  //horizontal lines
  if(horiz){
      line(random(x-((10000-frameCount)/200),x),y,random(x,x+((10000-frameCount)/200)),y);
  }
  //vertical lines
  else{
      line(x,random(y-((10000-frameCount)/200),y),x,random(y,y+((10000-frameCount)/200)));
  }
  //ends the program at 10000 frames with a 'fin' message
  if(frameCount>10000){
     fill(255);
      background(0);
      textSize(100);
      textFont('Georgia');
      textStyle(ITALIC);
      text('fin', 240, 240);
      noLoop();
  }
}
