Robert Member since : Jul 30, 2003 Messages : 1	Jul 30, 2003 at 4:13 PM I need to get the size of an Image, to decide if it should be displayd or not. How can I go about it using PJA? Thanks Robert

For example, this JSP code displays the width and height of an image : ------ <%@ page import="java.awt.,java.awt.image." %> <% Image im = Toolkit.getDefaultToolkit().getImage ("/path/to/imageFile"); MediaTracker tracker = new MediaTracker(new Frame()); tracker.addImage(im, 0); tracker.waitForAll (); %> Image size : <%= im.getWidth (null) %>, <%= im.getHeight (null) %> --- Manu (moderator/modérateur)
