i am converting my image pixel as a string and print of its length then i get output is given in example image.  
what is wrong with it.

```auto

void function()
{
  for(int x=0; x<img.height;x++)
  {
       
    for(int y=0; y < img.width; y++)
    {
       int i = y+x*img.width;
        
         s = str(i);
     print(s.length());
          
 }          
   
  }
    
}

```

and please tell how to formatting it in 100\*100 digit. without using “\n” or “\r” ;

Hey there !

It a bit unclear what the problem is. Could you give a more in-depth example ?

if you actually want to print the string lengths in a 100x100 grid  
in the console just build a string equivalent to a row of the image  
then output it with println instead of print. it probably won’t line  
up but you could pad the numbers (something [like](https://processing.org/reference/nf_.html)) you get to some length to give you  
an even print out

```auto
void function()
{
  String s;  
  for(int x = 0; x < img.height;x++)
  {
	s = "";//this is terrible should use something like a string builder or whatever processing has
	for(int y = 0; y < img.width; y++)
    {
       s += y + x * img.width;
	}
	println(s.length());
  }   
}

```
