Can i add one string in bse64 string ?

Question

Hello,
I am developing a small paint program. I am converting image into base64 and then decode base64 to display image on canvas. It is working fine. Now I am getting problem during when i am adding one string manually to the encoded string like this:
public String getImage(String s1){       
     byte abyte0[] = canvas.toByteArray(canvas.getBufferedImage());
     if((abyte0!= null))
           System.out.println(scheck); // this is extra string
        System.out.println(b.encode(abyte0)+scheck);
         return b.encode(abyte0)+scheck;
    return null;
}After that i am saving this data to database. When i am displaying image(after decode). it gives me nullpointer exception. with Illegal base64 String. Please help and tell me how to add one string at the last of base64 string. And how to separate this string from it without effecting base64 string. Please help me.
Thanks in advance.
Manveer.

Hi hood1,
2 options:
1) You can add many waveforms by combining them into one Array.
2) Use the Waveforms tools, that give you many option for adding waveforms. one after the seconed or adding the Y array of a waveform to other Y array of second wave form, and so on...
Hope it Helps...
