Perfect rounded content box without jaggies

dazsly · 27 Sep 2006 at 11:42

Hi im trying to create content boxes with rounded corners but when i save to giff and import into my html you can see the jaggies unless I use a white background, How can I create graphics that have anti-aliasing? is their a free program that could create them?

I use xara x1 and photoshop elements.

I know they are not major packages but I only work for a small company.

By the way I know xara uses AA but that still doesn't make a difference.

You need to make use of an alpha channel, enabling partial transparency. This will give you smooth corners on a transparent background. PNG-24 offers this, but there's one small issue with this and that's that IE versions <=6 don't support the alpha transparency without a bit of extra trickery.

There are several workarounds:
