Background Image won't load

Hi All-
I’m attempting to get this fork process, to run over the top of a background image, instead of the default neutral single color. I’ve loaded the image into the sketch data file, and attempted to set it up and draw it, but I just can’t figure out how to connect the dots so that the image displays in the background while the code runs its color process in the foreground. I keep getting a “bg is not defined” error in the log.

with this reduced code:

PImage bg;

void setup() {
  size(1200, 600);
  bg = loadImage("BayBridgeSunset_1200x600.png");
}

void draw() {
  image(bg,0,0);
  if ( frameCount%60 == 0 ) println(nf(frameRate,0,1));
}

it work, but need about 4 sec to load here.
the FPS i see about 35.


the

	background(bg);

only ends in error.

You’re using :

PImage = bg;

but that‘s not a correct way to define a variable…
Instead use :

PImage bg;
