Im drawing some polygons with PHP GD imagepolygon(). The problem is that i got alot of visible pizels, is there a way to make them smoother?
The included image shows the problem, on all the edges i have quite heavy pixelating.

[EDIT]
I have tried to use imageantialias() but i dont get it as good as im aiming for.
I think that i will have to take a look at vector graphics, anyway, here is the image with anti-aliasing if anyone is interested

If your GD image resource is a true color one and you are not using the alpha component (transparency), you can call imageantialias() to enable anti-aliasing.
