Hi all

I've a problem with the first "for" cicle in my code.
The application use a array (pixels[]) of video library and put all the content of array (hex color) in a string using "," as separator. When numPixels = 36100 the application take 40 seconds for make all the cicle....but is very important for me to reduce the second taken for this cicle. What can i do?

Thanks

 {  
     frame_stream=hex(video.pixels[1])+ ",";     
     for (int i = 1; i < numPixels; i++) { 
            frame_stream= frame_stream + hex(video.pixels[i]) + ",";          //crea la stringa contenente la il frame       
               }
            myServer.write(frame_stream);                      //invia il dato
            myServer.write(0);                                //invio la fine del data frame
            saveFrame("/immagini/videocamera-####.jpg");          //Salva il frame ogni X tempo
            frame_stream="";        //Scrive
            delay(3000);
            println("Finito invio dati");
                frame_stream="";
         }
