Hi all!
I found and try to adapt this code:
public final float[] BLUR3x3 = {
0.1f, 0.1f, 0.1f, // low-pass filter kernel
0.1f, 0.2f, 0.1f,
0.1f, 0.1f, 0.1f
};
This is a class i write to performe a blur proceccing to the loades image:
public void Blur_actionPerformed(ActionEvent e)
{
float[] data = BLUR3x3;
if (g_rast != null)
{
Graphics2D l_g2 = (Graphics2D) image.getGraphics();
ConvolveOp cop = new ConvolveOp(new Kernel(3, 3, data));
l_g2.drawImage(image.image2, cop, 0, 0);
image.repaint();
}
}
and ImageClass image;
BufferedImage image2;
ImageClass is a file that extends Component and declares BufferedImage
image2;
<b>I have this problem<b>: when I run my program I see these messages:
Exception in thread "AWT-EventQueue-0" java.awt.image.ImagingOpException:
