The Dimension of an Image file

[Mohamed Abu Zur]

How can I verify the dimension of an Jpeg or Gif file that I have in my server

directory (e. g c:/Dir/image.jpeg) within a servlet.
I want to verify the dimension before make the output.


Thanks in advance

Heres an example of resizing an image, pull out the bits that you
need....notice the getWidth, getHeight methods.

public void yoImage() {
MediaTracker media = new MediaTracker(this);
source = getImage(getDocumentBase(),"image.gif");
media.addImage(source,0);
try {
media.waitForID(0);
// scale down, half the original size
ImageFilter replicate =
new ReplicateScaleFilter
(source.getWidth(this)/2, source.getHeight(this)/2);
ImageProducer prod =
new FilteredImageSource(source.getSource(),replicate);
resizedImage = createImage(prod);
media.addImage(resizedImage,1);
media.waitForID(1);
}
catch(InterruptedException e) {}
}
