[1970]how to get the byte value of an image using getRGB()?
By Anonymous on 2008/06/19 15:13:36  Rate
Hi, 
  
  
 Does anyone know how I should complete the following code to get the byte value of the image? 
  
  
 private byte [  ]  getByteValue ( Image image )   {  
  
  
 byte [  ]  byte_data; 
  
  
 int [  ]  dest = new int [ image.getWidth (  ) *image.getHeight (  )  ] ; 
 image.getRGB ( dest, 0, image.getWidth (  ) , 0, 0, image.getWidth (  ) , image.getHeight (  )  ) ; 
 ......... 
 ......... 
  
  
 //should return the byte value of the image 
 return byte_data; 
  } 
public int getWidth()
