This is the first of a three part video on JavaScript design by Douglas Crockford, one of Yahoo!'s JS gurus. Its a very nice explanation of some of the trickier bits of JS object creation.
I don't know about you, but I happen to find transparent and semitransparent layering to be one of the coolest effects for building web pages, and now, thanks to Mandarin Design I know know how to control opacity with ease. Check it out.
One of the big frustrations about CF8 image effects, is the lack of any way to get transparent writes or backgrounds. While most people think of transparent as just one more color, when you look at how Java handles pixels, you'll understand why Adobe didn't take the time to do this themselves.
Can you create an image with a transparent background, but it takes creating some Java objects. I'll be posting the code as part of an image effects set, but you an follow the steps here to figure out how to do it.
So, while working on stuff my IIS install randomly started spitting out a freaky error message. I did a Google search and came up with this blog post. No idea what brought it on, but follow the directions there and everything goes back to normal.
I ran into an interesting problem with ColdFusion 8's image functions. I wanted to compare my image from before I added my effect, and my image after. Simple right? Well no, no its not. I'm doing my image manipulations in function, so I wanted to pass in the original image, and save the result to a new variable, but I kept coming out with two copies of the same image. It took me a bit, but I finally found a solution.
