Antialiasing with PHP

Today i updated the website of our company. And i also managed to fix one thing that bothered my since it existed: Smooth, antialiased rounded edges in HTML. Well, i had rounded edges quite some time now. I did it with a special PHP image generator which generated rounded-edge images on the fly in the colors you needed. That worked quite well, but unfortunatly the rounded edges where not antialiased.
So today i looked at that matter again, and tried to use the ImageAntialias() function of PHP. Of course did that not work with ImageFilledEllipse() that i used. So i thought about a better solution to get an antialiased round edge. Suddenly the technique used in todays graphicscards came to my mind: Supersampling.
So now I have images with 10xAA. That was the trick: I "rendered" the image in a resolution 10 times higher than needed and then downsampled the image to the requested size using ImageCopyResampled(). It's a bit slow but since the images are cached anyway its not a big matter. And it works quite nice. If you want to take a look at it visit to www.eudig.com - Contact page

Away from work I'm also rather busy. Coming weekend I'll be away for a recreational with my youth group. Since I'm member of the staff I have quite some things to prepare.
