Saving cropped image to a file

Question

Hello,
I have a big image, I've cropped it into small slices and saved them in a 2-Dimensional array as an "Image" object.
Now I am trying to save each "Image" Object to an individual file.
Now it's really weird because I can save the very first image element in array as a file, but the rest of the elements are BLACK!
Below is the part of my code.
===========================================================
for( int i=0; i < slicedImageArray.length; i++ )
for( int j=0; j < slicedImageArray.length; j++)
BufferedImage bi =
new BufferedImage( slicedImageArray[i][j].getWidth(),
slicedImageArray[i][j].getHeight(),
BufferedImage.TYPE_INT_RGB );
bi.getGraphics().drawImage( slicedImageArray[i][j].getSlice(),
slicedImageArray[i][j].getXCoordinate(),
slicedImageArray[i][j].getYCoordinate(), null);
File sliceImage = new File("image" + i + j + ".jpg");
try
ImageIO.write(bi, "jpg", sliceImage);
catch(Exception e)
====================================================================
getSlice() method returns "Image object"
PLEASE HELP!

Answer 1

it is most likely because you are drawing the image off the range of the buffer:
bi.getGraphics().drawImage( slicedImageArray[j].getSlice(),
slicedImageArray[j].getXCoordinate(),
slicedImageArray[j].getYCoordinate(), null);
should be:
bi.getGraphics().drawImage( slicedImageArray[j].getSlice(),
0,
0, null);
