Cropping only righ and bottom

Question

Hi all,
I'm, as many of the thread writers :), kind of new to java, but everyday i like this language more :) I'm trying to make an image crop with variables the user can input themselves, it works now but not completely. The image displays on screen but when the cropping starts only pixels from the right and from the bottom dissolve. I used the next code to accomplish this.
public Image Crop()
          int iw = this.image.getWidth(null);
          int ih = this.image.getHeight(null);
          BufferedImage buffImg = new BufferedImage(iw, ih, BufferedImage.TYPE_INT_ARGB);
          Graphics2D CropIg = buffImg.createGraphics();
          buffImg = buffImg.getSubimage(1, 1, iw-HorCropVar, ih-VertCropVar);
          CropIg.drawImage(this.image, 0,0, this.label);
          setImage(Toolkit.getDefaultToolkit().createImage(buffImg.getSource()));
                        return Toolkit.getDefaultToolkit().createImage(buffImg.getSource());
       }Can anyone help me out with it? And does anyone know if i can (the way i use the crop method now) add a mouselistener to it, to decide the region to crop??
Thanks all!!

Answer 1

Well, when you do
buffImg = buffImg.getSubimage(1, 1, iw-HorCropVar, ih-VertCropVar);you are only adjusting the width and height, as your x,y position is
fixed at 1,1. So you only lose pixels on the right and bottom.
To use the mouse to select the region, you'll probably want to use a
MouseInputAdapter, which implements both MouseListener and
MouseMotionListener. You can use the mousePressed() method to determine
when the selection of an area has been started, the mouseDragged()
method to determine the area being swept out, and the mouseReleased()
method to determine when the selection has completed.
In your mouseDragged() method, you'll probably want to provide some
visual feedback that the selection is occurring; you can look [url http://java.sun.com/docs/books/tutorial/2d/index.html]here for
some possibilities on how to do this.
Good luck.
