Drawing a shader generated PGraphics onto a non OpenGL PGraphics object

@GoToLoop Thanks for your reply !

So I’ve tried adapting my code the following way :


	public void render(){
		this.image.beginDraw();
		this.image.filter(alphaOverlayShader);
		this.image.endDraw();
	}
	
	public PGraphics getImage() {
		PGraphics out = context.createGraphics(w, h);
		this.image.beginDraw();
		this.image.loadPixels();
		out.beginDraw();
		out.loadPixels();
		PApplet.arrayCopy(this.image.pixels, out.pixels);
		out.updatePixels();
		out.endDraw();
		this.image.updatePixels();
		this.image.endDraw();
		return out;
	}

But this still doesn’t work, or at least I am still doing something wrong…
