Image filters for iphone sdk development

I plan to develop an application for the iphone that uses image filters such as blur, sharpness, etc. I noticed that there are several approaches for this,

  • Use openGL ES. I even found sample code on the Apple iphone dev website. How easy is openGL for those who have never used it? Can image filters be implemented using the openGL framework?

  • There is a Quartz demo also posted on the Apple iphone dev website. Has anyone used this structure for image processing? How does this approach compare with an openGL card?

  • Do not use openGL and Quartz framework. Basically access the raw pixels from the image and perform the manipulations themselves.

  • Use any custom image processing libraries like this one . Do you know of any other libraries like this?

Can someone provide information / suggestions on which option is better? Your feedback is much appreciated. Thank!

Quartz does not have access to Core Image yet on iPhoneOS, so you cannot use Core Image filters like on MacOS.

I would go with a special library. OpenGL ES has a lot of overhead that you don’t want to miss out on if you are not using it for anything else.
