Hi every body, ir really need your hel, i was worhing with the 0115 Beta version of processing but i get the latest version and this code does not work in this, in the new one. how can i make it work?
HERE IS THE CODE   you need an image named: linean.gif







PImage silueta;
int ancho = 640;
int alto = 480;
boolean[] siluetabool = new boolean[ancho*alto];

void setup(){
 size(ancho,alto,P3D);
 silueta = loadImage("linean.gif");
 bitmapabool();
}

void draw(){
 loadPixels();
 for (int i=0;i<ancho*alto;i++){
   pixels[i] = color(0,10,int(siluetabool[i])*100);
 }
 updatePixels();
}


void bitmapabool(){
 for (int i=0;i<ancho*alto;i++){
   siluetabool[i]=!boolean(silueta.pixels[i] >> 16 & 0xFF);

I think only the String and String[] args currently work with boolean().
The other overloaded versions seem to be commented out in the source.
Ben is this correct?

just do this instead then:
!((silueta.pixels[i] >> 16 & 0xFF) != 0 );
or
(silueta.pixels[i] >> 16 & 0xFF) == 0;

yep, it's been removed. boolean of an int seemed excessive, when you can just use != 0 or == 0 to do the same thing.
