hop of those help? You don't need a library for this task.
You can create the new image that is resulted this way:
code :
BufferedImage newImage = new BufferedImage(width, height, imageType);
BufferedImage tempImage = oldImage.getSubimage(0, y, otherWidth, height);
Graphics2D g2 = newImage.createGraphics();
g2.drawImage(tempImage, x, 0, otherWidth, height, null);
g2.dispose();

How can I capture image and after crop the captured image and replace it with crop image?

hope this fix your issue It seems dublicate but it is not please look my question. , Try this, onActivityResult you will Returned data
code :
  @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {


    case Utils.CROP_IMAGE:
        if (resultCode == RESULT_OK) {
            // Create an instance of bundle and get the returned data
            try {
                Uri outputFileUri = data.getData();
                             String path = getRealPathFromURI(outputFileUri)

            } catch (Exception e) {
                // TODO: handle exception
            }
        }
        break;

    default:
        break;
    }
}
 public String getRealPathFromURI(Uri contentUri) 
 {
 String[] proj = { MediaStore.Audio.Media.DATA };
 Cursor cursor = managedQuery(contentUri, proj, null, null, null);
 int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
 cursor.moveToFirst();
 return cursor.getString(column_index);
}

Hope this helps Check image's field xtype. In old versions it was smartimge, now you need to use html5smartimage.
Example
code :
<items jcr:primaryType="cq:WidgetCollection">
        <image
            jcr:primaryType="cq:Widget"
            cropParameter="./imageCrop"
            ddGroups="[media]"
            fileNameParameter="./fileName"
            fileReferenceParameter="./fileReference"
            name="./file"
            title="Image"
            uploadUrl="/tmp/upload_test/*"
            xtype="html5smartimage">
        </image>

I want to crop image as above image (red line) but my code is seem incorrect.
code :
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;

public class Test {

    public static void main(String[] args) throws IOException {
        BufferedImage crop = new Test().crop(0.8509);
        System.out.println(crop.getWidth() + "x" + crop.getHeight());
        ImageIO.write(crop, "jpg", new File("Square.jpg"));
    }

    public BufferedImage crop(double amount) throws IOException {
        BufferedImage originalImage = ImageIO.read(Test.class.getResource("Cat.jpg"));
        int height = originalImage.getHeight();
        int width = originalImage.getWidth();

        int targetWidth = (int)(width * amount);
        int targetHeight = (int)(height * amount);
        // Coordinates of the image's middle
        int xc = (width - targetWidth) / 2;
        int yc = (height - targetHeight) / 2;

        // Crop
        BufferedImage croppedImage = originalImage.getSubimage(
                        xc, 
                        yc,
                        targetWidth, // widht
                        targetHeight // height
        );
        return croppedImage;
    }

}

How can i crop image using the HTML5 canvas and JavaScript in order to crop an image offline?

this will help If the image originated on the local domain, then you can easily crop it with html canvas.
But, if the image originated from another domain, you will run into CORS security errors: http://code.google.com/p/html5security/wiki/CrossOriginRequestSecurity
