用于 CategoryDistortionEffect 的 CIFilter 示例

发布于 2024-12-21 07:39:38 字数 135 浏览 4 评论 0原文

有人可以展示一个为 kCICategoryDistortionEffect 初始化 CIFilter 的示例吗？

我需要为我的摄影创建扭曲效果。我读到，在 IOS 5 中使用 CIFilter 是可能的。但我找不到合适的代码如何实现它。

我一直在寻找这个。到目前为止，它似乎在 iOS 5 中不可用。证据如下：

如果执行：

NSArray *properties = [CIFilter filterNamesInCategory:
                       kCICategoryBuiltIn];

您将看到它仅返回以下列表，不包含任何 kCICategoryDistortionEffect。它只包含：

CIAdditionCompositing,
CIAffineTransform,
CICheckerboardGenerator,
CIColorBlendMode,
CIColorBurnBlendMode,
CIColorControls,
CIColorCube,
CIColorDodgeBlendMode,
CIColorInvert,
CIColorMatrix,
CIColorMonochrome,
CIConstantColorGenerator,
CICrop,
CIDarkenBlendMode,
CIDifferenceBlendMode,
CIExclusionBlendMode,
CIExposureAdjust,
CIFalseColor,
CIGammaAdjust,
CIGaussianGradient,
CIHardLightBlendMode,
CIHighlightShadowAdjust,
CIHueAdjust,
CIHueBlendMode,
CILightenBlendMode,
CILinearGradient,
CILuminosityBlendMode,
CIMaximumCompositing,
CIMinimumCompositing,
CIMultiplyBlendMode,
CIMultiplyCompositing,
CIOverlayBlendMode,
CIRadialGradient,
CISaturationBlendMode,
CIScreenBlendMode,
CISepiaTone,
CISoftLightBlendMode,
CISourceAtopCompositing,
CISourceInCompositing,
CISourceOutCompositing,
CISourceOverCompositing,
CIStraightenFilter,
CIStripesGenerator,
CITemperatureAndTint,
CIToneCurve,
CIVibrance,
CIVignette,
CIWhitePointAdjust

并且缺少我们感兴趣的：

CICategoryDistortionEffect,
CIBumpDistortion,
CIBumpDistortionLinear,
CICircleSplashDistortion,
CICircularWrap,
CIDisplacementDistortion,
CIGlassDistortion,
CIGlassLozenge,
CIHoleDistortion,
CIPinchDistortion,
CITorusLensDistortion,
CITwirlDistortion,
CIVortexDistortion

I've been looking for this to. Thus far it appears that's not available in iOS 5. Here's the evidence:

If you execute:

NSArray *properties = [CIFilter filterNamesInCategory:
                       kCICategoryBuiltIn];

you'll see that it only returns the following list which doesn't contain any of the kCICategoryDistortionEffect's. It only contains:

CIAdditionCompositing,
CIAffineTransform,
CICheckerboardGenerator,
CIColorBlendMode,
CIColorBurnBlendMode,
CIColorControls,
CIColorCube,
CIColorDodgeBlendMode,
CIColorInvert,
CIColorMatrix,
CIColorMonochrome,
CIConstantColorGenerator,
CICrop,
CIDarkenBlendMode,
CIDifferenceBlendMode,
CIExclusionBlendMode,
CIExposureAdjust,
CIFalseColor,
CIGammaAdjust,
CIGaussianGradient,
CIHardLightBlendMode,
CIHighlightShadowAdjust,
CIHueAdjust,
CIHueBlendMode,
CILightenBlendMode,
CILinearGradient,
CILuminosityBlendMode,
CIMaximumCompositing,
CIMinimumCompositing,
CIMultiplyBlendMode,
CIMultiplyCompositing,
CIOverlayBlendMode,
CIRadialGradient,
CISaturationBlendMode,
CIScreenBlendMode,
CISepiaTone,
CISoftLightBlendMode,
CISourceAtopCompositing,
CISourceInCompositing,
CISourceOutCompositing,
CISourceOverCompositing,
CIStraightenFilter,
CIStripesGenerator,
CITemperatureAndTint,
CIToneCurve,
CIVibrance,
CIVignette,
CIWhitePointAdjust

and is missing the one's we're interested in:

CICategoryDistortionEffect,
CIBumpDistortion,
CIBumpDistortionLinear,
CICircleSplashDistortion,
CICircularWrap,
CIDisplacementDistortion,
CIGlassDistortion,
CIGlassLozenge,
CIHoleDistortion,
CIPinchDistortion,
CITorusLensDistortion,
CITwirlDistortion,
CIVortexDistortion

您可以使用以下代码查看所有过滤器类型

NSArray *filterNames =[CIFilter filterNamesInCategory:kCICategoryBuiltIn];
NSLog(@"Built in filters");
for (NSString *currentFilterName in filterNames)
{
    NSLog(@"%@", currentFilterName);
}

You can see all the filter types by using below code

NSArray *filterNames =[CIFilter filterNamesInCategory:kCICategoryBuiltIn];
NSLog(@"Built in filters");
for (NSString *currentFilterName in filterNames)
{
    NSLog(@"%@", currentFilterName);
}
