Hi I used to run  this sketch on OpenProcessing with no problem. I now get this error:

Hi,

I'm a processing.js newcomer...

my sketch is not working with processing.js. I cant figure why.

It's working with Processing 1.5 ok: here.

I've used a preload command and supplied the image file. The sketch doesn't use any library.

I've tried both P3D and OpenGl with no success.

Can you point to my error plz?

Thanks in advance.

Hi,
I'm drawing on a PGraphics object with transparent background. I want to copy it to a PImage (will be tinted afterwards), and keep the transparency. It works when I save my PGraphics object to a png and load this file to a PImage.

I'd like to find a way to do the same without saving. I tried PGraphics.get(), but it doesn't keep alpha values. How should I do?

Thanks for answering.

Hi!

using controlP5, I cant get a tooltip to work on any control as soon as I move these controls to a controlWindow...

Thanks for your help.

Hi,

I'm using saveFrame to save a frame from my applet. It works perfectly locally. When I sign my applet and post it to the web, nothing happens. Is it sving to a temp folder???

Is there a way to open a "save to" dialog on the user's computer?

I'm experiencing with rotative masks: My applet

I experience weird deformations of my grid mask, though I use single rotations parallel to the axis... No rotation should alter a grid.  Any idea?

Thanks

PImage maskimage;
PImage backgroundimage;
PGraphics pg;
String maskname="mask";
int i=0;
float count=0;
boolean marche=false;
boolean inver=false;
int cycle=0;

void setup() {
  size(800, 600,P3D);
  backgroundimage = loadImage("img.jpg");
  maskimage = loadImage(maskname+".jpg");
  backgroundimage.loadPixels(); 
  pg = createGraphics(800, 600, P3D);  
  imageMode(CENTER);
  noCursor();
  smooth();
}

void draw() {
  background(0);  
  if(marche)count+=.03;
  pg.beginDraw();
  pg.background(0);
  pg.fill(255);
  if (inver) {
    pg.filter(INVERT);
  }
  pg.endDraw();
 
  pg.translate(width/2, height/2);
  if(cycle==0){
    pg.rotateX(count);
    pg.translate(-pg.width/2,maskimage.height/2-pg.height/2);
  }
  if(cycle==1){
    pg.rotateY(count);
    pg.translate(maskimage.width/2-pg.width/2,-pg.height/2);
  }
  if(cycle==2){
    pg.rotateZ(count);
    pg.translate(-pg.width/2,-pg.height/2);
  }
 
 pg.image(maskimage,width/2-maskimage.width/2,height/2-maskimage.height/2);
   backgroundimage.mask(pg);
   image(backgroundimage, width/2, height/2);
}

void mousePressed() {
  if (mouseButton == RIGHT) {
    inver=!inver;
  }else{
    marche=true;
    cycle++;
    if(cycle==3)cycle=0;
  }
}
void mouseReleased() {
  if (mouseButton == RIGHT) {
    inver=!inver;
  }
}

Hi!

I'm trying to render a cube as a lit edges skeleton (see code below). Strokes are not affected by lights in any rendering modes and I dont find how to do it.
Thanks for your help!

void setup()
{
  size(640, 360, P3D);
  stroke(255);
  noFill();
}

void draw()
{
  background(0);
  translate(width / 2, height / 2);
 
  // Orange point light on the right
  pointLight(150, 100, 0, // Color
             200, -150, 0); // Position
 
  rotateY(map(mouseX, 0, width, 0, PI));
  rotateX(map(mouseY, 0, height, 0, PI));
  box(150);
}
