How to resize my loadImage?

Hooga — Wed, 06 Jan 2016 04:47:37 +0000

I originally got a program that reads the pixels in a picture, In order for it to work the picture has to be the same size as the canvas or for you to see it. Well I loaded in a 1920 x 1080 picture and loaded it into a 1000 x 500 canvas, I set the images (image(img, 0, 0, width, height);) size to the height and the width of the canvas, but when I load the picture using the loadImage method it loads the image in its original resolution in the background where I cant see it, I want it to load the image into the size of the canvas, how can I accomplish this? Code:

PImage img;
int direction = 1;
float signal;
int imgX = 0;
int imgY = 0;
int w = width;
int h = height;




void setup() {
  size(1000, 500);
  //fullScreen();
  noFill();
  frameRate(60);
}




void draw() {
  // int boxX = img.width/2;
  //int boxY = img.height/2;
  img = loadImage("203.jpg");

  background(255);



  if (mousePressed) {
    int mx = constrain(mouseX, 0, width-1);
    int my = constrain(mouseY, 0, height-1);
    signal = my*width + mx;
  } else {
    //signal += 0.33*direction;
  }

 // set(imgX, imgY, img);  // fast way to draw an image

  int sx = int(signal) % width;
  int sy = int(signal) / width;
  color c = img.get(sx, sy);
  image(img, 0, 0, width, height);


  //rect(sx, sy, 10, 10);
  fill(c);
  rect(50, 50, 50, 50);

  print("Color " + c);
  println(" X " + sx + " Y " + sy );
}

In order for this code to work you have to set the canvas size to the resolution of the image, and I do not want that. Plus the canvas size cannot be re-sized.

If you run this program at the top left corner you will see a box that will copy the color of the pixel where your mouse is at, hover over any pixel to see what my problem is.

How do I change size while the sketch is running?

How do I change size while the sketch is running? The surface.resizable(true); does not allow for the sketch to change the size. My goal is to be able to have a button in processing activate fullscreen, and be able to disable it.

Changing Size of Object Slowly

How would you go about changing the size of an object when you click the page. I realize there are many ways to do this but I specifically want the shapes to gradually increase/decrease given an array of numbers.

Exporting Application on machines with different screen resolutions

HenrySmith — Sun, 29 Mar 2015 19:47:49 +0000

Hi there, I am relatively new to processing and am trying to export an application for the first time. However the sketch did not appear as desired on every machine that I tried on. Then I released that it is because I make use of the size(displayWidth, displayHeight, P3D); command. Thus, obviously it only appeared well on screens with the same resolution as the screen of the PC I created the sketch on.

Can anyone suggest a way how to make a sketch appear properly on any screen resolution?

I think it involves in setting each and every coordinate relative to the screen width and height right? However thinks may be more complicated since I am making use of images which I assume need to be re-sized in some way.

So basically I want the sketch to be re-sized to accommodate the resolution of the screen while maintain the aspect ratio.

Any tips will be greatly appreciated!

How to change G4P font size?

There was a solution for this problem, but the discussion has been deleted. So how do I change the size of the text in text fields and labels?

Thank you.
