Quick and Dirty Way to get Image Dimensions

By davidjmedlock | May 7, 2004 | ColdFusion

img = tk.getDefaultToolkit().getImage("C:\image.jpg"); width = img.getWidth(); height = img.getHeight(); #width# #height#

I’m by no means a master of all things Java, but this is an easy way to grab the height and width of an image. I haven’t tried it with GIF’s just yet, but I think it’ll work… Enjoy!

Steveroot, have you found a solution on Linux.
I`m looking for a way to determine a photo`s width and height so if any one has any suggestions it would be very much apreciated.

SELECT image
FROM table

img = tk.getDefaultToolkit().getImage(“C:\www\www.yourdomain.com\images\#image#”);
width = img.getWidth();
height = img.getHeight();

#image#

Tom Tedeschi August 25, 2004 at 10:34 am: Looks great, but I get this error… any thoughts?
Element GETDEFAULTTOOLKIT is undefined in TK.
The error occurred in D:\Inetpub\flatfishdesign\ii\asis\imageSize.cfm: line 4

3 :
4 : img = tk.getDefaultToolkit.getImage(“./images/espn.gif”);
5 : width = img.getWidth();

jonese May 18, 2004 at 1:47 pm: try removing the () after getDefaultToolkit so it becomes img = tk.getDefaultToolkit.getImage(“C:\image.jpg”);
QCWmstr May 10, 2004 at 7:17 pm: I tried using this script and CF didn’t like the second period on the first script line – the one after getDefaultToolkit()
Am I doing something wrong?
