Circular Thumbnails in PHP?

[Anon]

Anybody know of an easy way to make a circular thumbnail image in PHP?

For example:

Lets say I have a picture and I want to make a thumbnail of the center of the picture. I want to have the resulting image in a circle instead of a square or rectangle. I suppose a color could be used (such as black) on the corners so that the image appears to be a circle if placed on a black background.

Anyone have a code snippet to do this?

Thanks in advance.

First off you can't create an actual circular image. Images stored on computers use hight and width values that cause the actual image to be a square/rectangle.

Besides that you could write a script to designate a circle in the middle of an image and then turn any pieces of the image outside of that circle transparent.

Sorry I don't have any code available to help you, but it souldn't be to hard once you get the circle drawn. You will need to have teh GD library installed, and know how to use the Image functions (http://download.php.net/manual/en/ref.image.php). Take a look at ImageFillToBorder it'll probably do what you want, once you get your circle drawn.

I realize that you can't make an actual circular image and that I'd have to use some sort of fill command. I'll take a look at ImageFillToBorder. Just need to figure out how to do this on an already existing image (as opposed to creating a new graphic, drawing a circle, and then filling to border).

Thanks!

I didn't mean to imply that you didn't know that you couldn't create a circular image. I just feels it's best to give complete information since many people who read this board are beginners and I have seen people looking to make an actual circular image.

I hope you get it working the way you want.
