由于 iPhone 中不存在 coreImage 框架(至少到 iOS 4.0),因此您必须手动进行图像过滤。您必须迭代图像中的每个像素并对其进行处理。此主题讨论了 iphone 中的各种图像过滤效果,非常有用..这些家伙说他们成功地将 imageMagick 移植到 iOS,但我从未尝试过。.此外,我还问了关于在 iOS 中实现宝丽来滤镜的问题,虽然没有得到很好的答案,但问题本身可能会有所帮助..
As coreImage framework is not present in iphone (atleast upto iOS 4.0), you will have to do image filtering by hand..You have to iterate through each pixel in an image and work on it..This thread discussed about various image filtering effects in iphone and is very useful..These guys say they are successful in porting imageMagick to iOS but I never tried that..Also I asked a question about implementing polaroid filter in iOS, though it didnt get a good answer, the question itself might be helpful..
