Hi everybody.

I'm using codeanticode.syphon and I really don't understand how to create a PImage of my sketch

to send it to syphonServer with the method .sendImage(PImage).

How can I pass all the things happening in the "draw() to a PImage??

It's probably a silly question but I really can't understand how to...

Thanks in advance.

Thanks, I've already look at that but what if I'm using many custom class and libraries?

For example: (this is not the real code but only an example..)

SyphonServer server;
PGraphics canvas;
//Fisica library
FWorld world;
FCircle circle;
void setup()
{
size(800,600);
canvas = createGraphics(800,600);
//Fisica stuff
Fisica.init(this);
world = new FWorld();
circle = new FCircle(30);
world.add(circle);
//Syphon
sever = new SyphonServer(this, "Processing Syphon");
}
void draw()
{
canvas.beginDraw();
canvas.background(255);
//How can i tell to these instances to be drawed on canvas?? if i try canvas.world.. give me errors..
world.step();
world.draw();
canvas.endDraw();
image(canvas, 0, 0);
server.sendImage(canvas);
}

How can i use custom stuff on the PGraphics? if I draw an ellipse with canvas.ellipse() it works..but i need to draw my stuff on that and I don't know how to pass this stuff on the PGrapchics.

Thanks a lot.

It's funny I've never thought about it.
Mebe b/c I haven't explored third-party libraries that much.

I guess a PGraphics object allows a set of Processing's official drawing functions only.
I wonder whether it'd be enough for you of just sending a "copy" of current canvas to your SyphonServer instead?

Like this -> server.sendImage( get() );
