Flip the Video Capture on the X axis

in Core Library Questions • 2 years ago

Does anyone know a good way to do this ?

First thoughts are to use loadPixels() and updatePixels(), and redraw it as cam.width-x ...

but my video feed is only a portion of my sketch, and it's not in a Pgraphic buffer,

so i'm a little worried about flipping my whole sketch...

Any thoughts/leads are appreciated.

Should this flip the video capture on the x-axis?

import processing.video.*;

Capture cam;

void setup() {

size(640, 480);

cam = new Capture(this, 320, 240);

}

void draw() {

if (cam.available() == true) {

cam.read();

pushMatrix();

scale(-1,1);

image(cam, 0, 0);

popMatrix();

}

Assuming that your sketch width is same as the video frame/image width. This should flip the image horizontally (i.e. Mirror).

pushMatrix();

scale(-1,1);

image(webcam.get(),-width,0);

popMatrix();
