Obviously, I've gone ahead and filled the screen with my seamlessly repeating frogeye pattern. I'll go ahead and escape out of here and I went ahead and save this thing as Frog eye pattern.psd and it includes the live frog pattern layer. So you can play around with it, if you want to. Then I also saved my work inside Pixel Bender as Kaleidoscope.psd. Now what about those of you who would like to write your own filters? What do you do? Well, I'm not going to show how. I'm not going to provide a tutorial. I could spend an entire series on that. But I'll show you where to go and provide a little brief overview for you.
And I'm going to switch over here, I'm taking advantage of this thing under Windows Vista which is Windows key + Tab. And I'm going to go ahead and tab over to my browser. I'm looking once again at http://labs.adobe.com/downloads/ pixelbender.html and toward the bottom of this page, at least right now this is the way it is, you'll find the Pixel Bender toolkit, which is different for the Mac and a PC. So download whichever one makes sense for you. And part of that is the actual Pixel Bender toolkit right here. And what you can do in the Pixel Bender toolkit is you can write your own kernels, if you want to. Or you could load existing kernels. For example, in this case I want to have loaded kaleidoscope.pbk. And you can do that by going up to the File menu and opening a filter like so.
And you just have the hunt around for it, of course. We find out that this comes to us from Petri Leskinen of Espoo, Finland. That's so awesome. And he did it in January of 2008 or she did, I don't know. That's a while back. What an awesome filter it is! And you can also create your filters by the way. And if you go ahead and choose this New Kernel Filter right there, then the Pixel Bender toolkit will go ahead, I'll make the toolkit a little taller and drag this bar up so that I have more space devoted to the code. It will go ahead and put in the essential information inside of which you need to go ahead and enter whatever codes you want to enter, whatever scripting.
It's usually built around this evaluatePixel guy right there, but there is some other stuff you can do as well. And if you want to find what that stuff is, why then, you want to go ahead and checkout this thing right here. It's the Developer's Guide, which is included along with that packet that you download from labs.adobe.com. And this gets you started. There's also a Reference Guide that's much longer that goes into detail about all the tags that are available to you. But this one gets you started and it even includes a little bit of code here and there that you can copy and paste right into the toolkit if you want to in order to get started.
And they've done a really good job. What you just have to keep in mind is when they're changing things up for you and they're giving you new information, then they put it in Bold. So in this case for example, if we'd already been building along with the guide right here, then this new bit of information in bold is all that we'd copy and paste into the toolkit in order to make the modified script work. And then back there inside of the toolkit you click Run in order to run your toolkit. You'll see all of your options here, you can actually modify them, you can load a sample image. So you can really test out your work.
They've done a great job. So I just want to give you a sense of what your options are. I leave it to you to investigate more on your own. In the next and final chapter of this series we'll take a look at how to record actions inside Photoshop.
