Ketai camera with Filter (THRESHOLD)

FeongxD

Hi, currently working on a camera app. in Android mode i'm new in processing. i dont know if my filter code is wrong, as i got it from the internet. the result i got is just showing without any filter.

i'm currently using this example code provided by ketai library, how can i combine with with the filter :

   import ketai.camera.*;

KetaiCamera cam;

void setup() {
  orientation(LANDSCAPE);

  imageMode(CENTER);
  cam = new KetaiCamera(this, 320, 240, 24);
  cam.filter(THRESHOLD);
}

void draw() {

  image(cam, width/2, height/2, width, height);
}

void onCameraPreviewEvent()
{
  cam.read();
}


void mousePressed()
{
  if (cam.isStarted())
  {
    cam.stop();
  }
  else
    cam.start();
}
void keyPressed() {
  if (key == CODED) {
    if (keyCode == MENU) {
      if (cam.isFlashEnabled())
        cam.disableFlash();
      else
        cam.enableFlash();
    }
  }
}

        if (keyCode == MENU) {
          if (cam.isFlashEnabled())
            cam.disableFlash();
          else
            cam.enableFlash();
        }
      }
    }

jrmasiero

erase the "cam.filter(THRESHOLD);" in the void setup

and put the filter after the image() in the void draw

void draw() {
  image(cam, width/2, height/2, width, height);
  filter(THRESHOLD);
}
