hi
i need major help
trying to do a research topic (see earlier questions) and was given this code;
PImage myImage;
void setup(){
   size(200,200);
   myImage = loadImage("myImage.gif");
   // drag image into processing text-window then it
   // will be copied to <sketch-path>/data/myImage.jpg
}
void draw()
{
   myImage.loadPixels(); // not sure this is needed
   for ( int x = 0; x< myImage.width; x++ )
   {
       for ( int y = 0; y < myImage.height; y++ )
       {
           int i = y * myImage.width + x;
           
           if ( myImage.pixels[i] == color(0) ) {
               // black
               ellipse(x,y,10,10);
           }
           else
           {
               // white
           }
       }
   }
}
to try and help
when trying to adapt it so i could load my own image, make it two colours etc i get unexpected symbol ignored as part of this code;
 int i = (y * polarfleece.width + x);
the whole code i am trying to put in is below;
void setup () {
size (600,600);
polarfleece = loadImage ("polarfleece.JPG");
image(polarfleece, 0, 0);
filter(GRAY);
filter(POSTERIZE, 2);
}
 void draw ();
{
 polarfleece.loadPixels ();
for (int x = 0; x< polarfleece.width; x++)

 for (int y=0; y< polarfleece.height; y++)

  int i = (y * polarfleece.width + x);
}
  if (polarfleece.pixels [i] == color(0) ) {
    ellipse (x,y,40,40) ;
  }
  else
  {
    if (polarfleece.pixels [i] == color(1) ) {
    }


i am trying to get processing to identify a black / white pixel and if the pixel is black place a drawing there (in the above case an eclipse)

hope someone can help me
thanks
