This is my code:
void setup() {
size (360,443);
PImage gino = loadImage("gino.jpg");
background(gino);
}

void draw() {
stroke(0);
strokeWeight(2);
if(mousePressed) {
line(mouseX, mouseY, pmouseX, pmouseY);
}
}

In this case, to draw the line I have to hold down the mouse button, but I need that I click the mouse in one point of the window and then in another so the program draw a continuos line.
This the problem Sad

I hope I have been clear:)

try this out

Code:

ArrayList lines = new ArrayList();
PVector node;

void setup() {
  size (360, 443);
  
  strokeWeight(2);
}


void draw() {
  background(250);
  
  if(mousePressed) {
    PVector node = new PVector(mouseX, mouseY);
    lines.add(node);
  }
  
  stroke(0);
  for (int i = 0; i < lines.size(); i++) {
    if (i > 0) {
	PVector prevNode = (PVector)lines.get(i - 1);
	PVector node = (PVector)lines.get(i);
	line(prevNode.x, prevNode.y, node.x, node.y);
    }
  }
}

In your case you need to draw your image in the draw method

Hope that helps
