Hi,
I am using a code to read a grayscale image and store the pixel value in a 1D array. But the code is taking a default image(though i am providing the complete path for the image to be loaded) and the height and the width are returned as -1. Also tell me how to get the pixel value and how to store in 1D array.
my code:
import java.awt.Image;
import java.awt.*;
import java.awt.image.PixelGrabber;
class ImagetoPixel extends Frame
{ String imagePath;
int width, height;
Image image = null;
PixelGrabber grabber;
int []pixels;
MediaTracker tracker;
public static void main(String args[])
{
ImagetoPixel obj = new ImagetoPixel();
obj.testFunction();
}
void testFunction()
{
System.out.println("The function is to use object");
image = Toolkit.getDefaultToolkit().getImage( "C:\\Documents and Settings\\swetaseng\\My Documents\\My Pictures\\fingerprint.jpeg" );
if(image ==null)
{
System.out.println("No Image");
}
else
{
}
System.out.println(image);
width = image.getWidth(this);
height = image.getHeight(this);
grabber = new PixelGrabber(image, 0, 0, width, height, pixels, 0, width);
System.out.println("width = " +width);
System.out.println("height = "+ height);
}
}
