以上介绍了几个滤镜模式,假设想查询系统内置了多少种滤镜,能够运行下面代码查看:
//查看全部内置滤镜
NSArray *filterNames=[CIFilterfilterNamesInCategory:kCICategoryBuiltIn]; for (NSString *filterNamein filterNames) { CIFilter *filter=[CIFilterfilterWithName:filterName]; NSLog(@"\rfilter:%@\rattributes:%@",filterName,[filterattributes]); }
以下截取控制台输出的部分滤镜消息。
就拿CIZoomBlur滤镜模式来说。打印出来的信息。能够看到,里面定义了一些属性(每种滤镜,所含有的属性会有区别。在使用的时候,特别要注意)。
属性名称能够使用定义好的结构体成员kCIInputImageKey。或者直接@"inputImage"调用,都是表示输入的图片。
inputImage相应的value里面定义了这个属性是什么类型的。属性描写叙述等。
假设须要其它滤镜模式的能够去查看。
