Picture Manipulation

  Picture
    ==>  pixels - Picture Elements
      ==> Position
             ==> x (column), y (row) coordiate
                    0, 0 is upper left corner
      ==> Color
             ==> red     0 - 255
             ==> green   0 - 255
             ==> blue    0 - 255


For loop - variation on the while loop

    The 3 parts of the while loop 
       - initialization
       - condition
       - increment
     become combined on a single line in a for loop

   for ( <initialization> ; <condition> ; <increment> )
     {
       <statements> ;
     }

The following while loop
   int x;

   x = 1;
   while ( x <= 10 )
     {
       System.out.println (x);
       ++x;
     }

becomes the following for loop
   int x;

   for ( x = 1 ; x <= 10 ; ++x )
     {
       System.out.println (x);
     }
