Adam- We are using a tool called imagemagick (www.imagemagick.com) to do our image comparison, very similar to the approach used in the presentation below (and it's free). We use imagemagick to compare a PDF report to a previously run version. This is extremely helpful for comparing reports in a language you can't read. I wrote our version in Perl but there is a Ruby interface to the image libraries.
We solved the image comparison problem using a 3rd party program to convert PDF's to images. Another program that may help you is Snagit which has a scrolling screen capture. That may be difficult to automate with Watir tho.

Ok here is the information that I was talking about. I don't actually have working samples but in the pdf he talks about the comparisons that he did and what he used to compare them. I don't know how you would automate it but here is the information. http://model.based.testing.googlepages.com/exploratory-automation.pdf Hope this helps! -----Original Message----- From: [EMAIL PROTECTED] on behalf of Sergio Pinon Sent: Sat 5/12/2007 11:21 AM To: [email protected] Subject: Re: [Wtr-general] Does anyone know how to capture an entire screenand compare with image? Back in February I attended the dt/td summit. There someone presented on how they captured screens and diffed them using a software called Eggplant. I can see if I can find the information. Chris McMahon might also have it. -----Original Message----- From: "qadude123" <[EMAIL PROTECTED]> To: "[email protected]" <[email protected]> Sent: 5/12/2007 12:07 AM Subject: [Wtr-general] Does anyone know how to capture an entire screen and compare with image? Hi, I'm a newbie with Watir and Ruby. I would like to capture the entire page and compare it to another image. I've seen that there is a ruby file called screen_capture.rb. How do I get this file? Does anyone have any working code to capture the entire screen ....including the part that's scrolled off the screen?
