[PC Carraway]

Thanks for the pointer/link.  I'll look in to it tonight.  Wish I could 
right now, but the phone's ringing off the hook.

Precia,

Well, this is the only one i've found, but as a Java newbie, i don't see 
how
to implement it via CF directly - as you have done with the
javax.swing.ImageIcon approach. I'd have to sit with it for a few days to
distill the essential functions from this class, see how they work, and 
try
and implement them via CF. But it seems it should work.

I've also found the same technique used in PHP and VB examples, read the
first few bytes and extract the height and width information from the
header.
In any case, i think it would be very useful to refine this for CF, as 
it's
probably the most commonly needed use of Java in CF.

I'm still on the lookout for an SWF solution.  Good luck if you find one
before me.

Precia,
thanks for the code snippet - and the example of using java within CF - 
it
works very well, for images. It's much faster than using the approach
Craig
indicated, via java.io.File and javax.imageio.ImageIO, or the Alagad
component. I wonder if that's because javax.swing.ImageIcon just grabs 
the
file header? Unfortunately it doesn't work for SWFs, but because the code
is
so clean, i'm thinking to use it for the images anyway and work out a
specialized solution for the SWFs

Thanks again,
:) nando

<cfscript>
function getImageWidth(imagepath)
{
 imgFile = createObject("java","javax.swing.ImageIcon").init(imagepath);
 imgFile.getImage();
 imgWidth = imgFile.getIconWidth();
 return imgWidth;
}
function getImageHeight(imagepath)
{
 imgFile = createObject("java","javax.swing.ImageIcon").init(imagepath);
 imgFile.getImage();
 imgWidth = imgFile.getIconHeight();
 return imgWidth;
}
</cfscript>
#getImageWidth(attributes.filepath)#
#getImageHeight(attributes.filepath)#
Hope this helps...
