In my application I need to put some effects on either a NSImage or an ImageView. I have been searching Google and this forum but I have not been able to find anything.

Can some one help or point me to a webpage that tells about it?

Please be more specific than "some effects". Tell us exactly which effect(s) you want.

Exactly what searches have you tried? Be specific.

When I google nsimage effects, the top hit is this:
http://www.cocoabuilder.com/archive/cocoa/238807-blur-nsimage.html

It contains example code using a CIFilter. Since CIFilter is the principal effects generator in Core Image, one should be able to use any single-image filter other than the "CIGaussianBlur" of the example without changing anything else in that code.

Here's a list of built-in CIFilter types:

If you've tried the example code and it fails, then please state that and post any error message, or describe the reason for failure.

Thanks chown33 I did find that blur method my self.

I looking for effects like rounded corners, border, grayscale, flip, mirror, sharpen and so on. All the effect I can get.
