How to delete an image?

first

Dear friends, I have designed an image and save it in my sketch folder. I want to delete this image from the sketch folder after an event such as mouse pressed. Can anyone suggest me how to delete an image from sketch?

I googled "delete file site: processing.org" and found this as my top result: https://forum.processing.org/one/topic/noob-how-to-delete-a-file-in-the-data-folder.html

Yes, but it is not working... did you typed the code present in the link? I have checked it. Try it your self:

import java.io.File;
String fileName;
void setup() {
  size(480, 360);
  background(0);
  ellipse(width/2, height/2, width/2, height/2);
  fill(255);
  save("image1.jpg");
}

void mousePressed() {
  fileName = dataPath("image1.jpg");
  File f = new File(fileName);
  if (f.exists()) {
    f.delete();
  }
}

It is not working.

koogs

save("image1.jpg");

this saves in the sketch folder, not the data folder. you are deleting from the data folder...

also, without a draw your code will finish after setup so there won't be time to press a key...

import java.io.File;

String fileName;
void setup() {
  size(480, 360);
  background(0);
  ellipse(width/2, height/2, width/2, height/2);
  fill(255);
  save(dataPath("image1.jpg")); // save in datapath
}

void draw() {
}

void mousePressed() {
  fileName = dataPath("image1.jpg");
  File f = new File(fileName);
  if (f.exists()) {
    println("deleting");
    f.delete();
  }
}

static final String IMG_NAME = "shot.png";

void setup() {
  size(400, 400);
  smooth(3);
  noLoop();

  blendMode(REPLACE);
  ellipseMode(CENTER);

  strokeWeight(3.5);
  stroke(-1);
}

void draw() {
  clear();
  fill((color) random(#000000));
  ellipse(width>>1, height>>1, width>>1, height>>1);
  saveFrame(dataPath(IMG_NAME));
}

void mousePressed() {
  if (mouseButton != CENTER)  dataFile(IMG_NAME).delete();
  else                        redraw = true;
}
