how do i get image width and height?

[mountainbiker]

i need a little simple java class file that if passed a image path/name (e.g., c:\pic1.gif, h:\pic2.jpg, etc.) that has two public static methods "returnWidth" and "returnHeight" returning the pixel width and height respectivitely of the passed image.

does anyone know if there is a similar existing class or who can point me in the right direction to create it?

what format are the images in (ie gif/jpg/tif/) etc ...

yes jpg, gif, png, etc. -- but prob okay to skip tiff and animated gif.

You will (depending on your JDK version) need to use either the javax.imageio package, or the JAI package.
