The image is clipped after convolve

Here is my code snippet:

class cursorextends JComponent{

GeneralPath cursor =new GeneralPath();

int width;

int height;

int gkRadius = 5;

public cursor(){

setBackground(Color.black);

cursor.moveTo(0.0f, 0.0f);

cursor.lineTo(0.0f, 20.0f);

cursor.lineTo(4.0f, 16.0f);

cursor.lineTo(5.0f, 17.0f);

cursor.lineTo(10.0f, 26.0f);

cursor.lineTo(12.0f, 26.0f);

cursor.lineTo(13.0f, 25.0f);

cursor.lineTo(8.0f, 14.0f);

cursor.lineTo(14.0f, 14.0f);

cursor.closePath();

width = cursor.getBounds().width;

height= cursor.getBounds().height;

}

publicvoid paint(Graphics _g){

super.paint(_g);

BufferedImage im2;

Graphics2D g2d;

im2 =new BufferedImage(width,height,BufferedImage.TYPE_INT_ARGB);

g2d = im2.createGraphics();

//Set the background to black

g2d.setBackground(getBackground());

g2d.clearRect(0,0,width,height);

g2d.setPaint(Color.gray);

g2d.fill(cursor);

// Blur the image

ConvolveOp blur =new ConvolveOp(new GaussianKernel(gkRadius));

BufferedImage im = blur.filter(im2,null);

Graphics2D g = (Graphics2D)_g;

g.drawImage(im, null,null);

}

}

Before i add the convolve operation, the generated image im

looks fine. However after i blur it, the generated image im2

is clipped. The width and height is different before the blurred operatoin.

Does anyone tell me why and what's the modification?
