                        //then returns it to be edited
$line1[2] = 'w'; //the line class follows ArrayAccess so can be used as an array to set chars
$line1['2:3'] = 'w'; //the index can also be a string with 2 numbers separated by
                 //a colon to denote a range this is the equivalent range to the above
                 //index it set the value from and including index a until and excluding
                 //index b
                 //you can also get a value using an index or range.
                 //you can also pass an instance of Slice which is what it is converted
                 //to internally
var_dump('w' == $line[new Slice(2, 3)]);//this will be true
$line1['3:5'] = 'er';//so index 3 and 4 will be set with this value.
$line2 = new Line($file->getWidth()); //you can also create a line
$file[] = $line2; //and add it to the file. it follows ArrayAccess as well
               //you can also use addLine for the same effect
$file[1] = $line2; //this has the same effect and setLine(1, $line2) can be used as well
unset($file[0]); //this removes the line at that index and reindex's the lines
              //so $file[0] === $line2
$line2['0:5'] = 'hello';
$line2['6:11'] = 'world'; //$line2 now says 'hello world         '
echo $line2; //the Line class has a __toString method so this will print out the contents
$file[] = $line1;
echo $file; //this will echo out the whole file line by line separated by the line
