PGraphics.image() not displayed with noSmooth() and P2D?

brontosplachna

When running this sketch, press any key to cause the PGraphics to be displayed. When P2D and noSmooth() are used, the PGraphics is displayed only momentarily. Is there a logical reason for this?

PGraphics pg1;

void setup() {
  size(640, 480, P2D); // remove P2D's to allow pg1 to be displayed
  noSmooth(); // or remove this to allow pg1 to be displayed
  background(0);
  fill(0, 255, 0);
  rect(0, 0, 100, 200);

  pg1 = createGraphics(width, height, P2D);
  pg1.noSmooth();
  pg1.beginDraw();
  pg1.background(255);
  pg1.fill(0);
  pg1.rect(100, 100, 100, 50);
  pg1.endDraw();
}

void draw() {
}

void keyPressed() { 
  background(0);
  image(pg1, 0, 0, width, height);
}

That is weird. You should consider filing a bug on GitHub (make sure you look to see if an existing bug has already been filed).

A workaround would be to get rid of your keyPressed() function and check the keyPressed variable in draw() instead:

void draw() {
  if(keyPressed){
    background(0);
    image(pg1, 0, 0, width, height);
  }
}

@brontosplachna -- was this ever filed as a bug on https://github.com/processing/processing/issues ?
