Hey,

For some weird reason my GSvideo capture mirrors the movement on the webcam.

Is there a way to reverse the X values so that when I move my hand to the right it shows
up with me moving my hand to the right on the screen?

I tried using a reverse method I found on the net, but it reverses the Y values...

Script is below


 import codeanticode.gsvideo.*;
 
public class ArrayHandle
{
public static Object[] reverse(Object[] arr)
{
List<Object> list = Arrays.asList(arr);
Collections.reverse(list);
return list.toArray();
}

}

int numPixels;
int[] backgroundPixels;
int[] currentPixels;
GSCapture cam;
int[] cords = {0};
int[] diffies;
int framer = 0;
int presenceSum = 0;

void setup() {
  size(640, 480);

  cam = new GSCapture(this, width, height);
      numPixels = cam.width * cam.height;
      backgroundPixels = new int[numPixels];
      currentPixels = new int[numPixels];
      loadPixels();
     
}

void draw() {
  if (cam.available() == true) {
    cam.read();
    cam.loadPixels();
    arraycopy(cam.pixels, currentPixels);
    // currentPixels = reverse(currentPixels);
 
  for (int y = 0; y < height; y++) {
    for (int x = 0; x < width; x++) {
        int loc = x + y * width;
        color currColor = currentPixels[loc];
    int currR = (currColor >> 16) & 0xFF;
    int currG = (currColor >> 8) & 0xFF;
    int currB = currColor & 0xFF;
    color bkgdColor = backgroundPixels[loc];
    int bkgdR = (bkgdColor >> 16) & 0xFF;
    int bkgdG = (bkgdColor >> 8) & 0xFF;
    int bkgdB = bkgdColor & 0xFF;
    int diffR = abs(currR - bkgdR);
    int diffG = abs(currG - bkgdG);
    int diffB = abs(currB - bkgdB);
    presenceSum += diffR + diffG + diffB;
    if (currG == bkgdG) {pixels[loc] = color(255);
    } else {pixels[loc] = color(0);}
    }
  }
  }
   
    updatePixels();
   
    rect(10, 10, presenceSum * 0.000005, 20);
    //abs what is abs in trig?
    //beginShape();
    //vertex(50, 60);
    //vertex(100, 200);
    //endShape();
    //dist() computes the distance between previous value and current value
    // map() will map input to a set range mouseX, 60, 180 etc.
    if (framer > 5 ) {
    arraycopy(cam.pixels, backgroundPixels);
    // backgroundPixels = reverse(backgroundPixels);
  framer = framer - 5;
presenceSum = 0;
}
    else {
    framer++;}
   
    if(Arrays.equals(currentPixels, backgroundPixels)) { // no test right now
  }
      else { // no test right now
    }
     
     
   
    cam.updatePixels();

   
    // color currColor = video.pixels[i];
    // image(cam, x in box, y in box);
    // The following does the same, and is faster when just drawing the image
    // without any additional resizing, transformations, or tint.
    // set(160, 100, cam);
