TuSDKFilterProcessorBase Class Reference

Inherits from	SLGPUImageOutput : NSObject
Declared in	TuSDKFilterProcessorBase.h

Overview

A GPU Output that provides frames from external source

Other Methods

`isOriginalOrientation`

传入图像的方向是否为原始朝向，SDK 将依据该属性来调整人脸检测时图片的角度。如果没有对图片进行旋转，则为 YES

@property (nonatomic, readonly) BOOL isOriginalOrientation

Declared In

TuSDKFilterProcessorBase.h

`runBenchmark`

This enables the benchmarking mode, which logs out instantaneous and average frame times to the console

@property (readwrite, nonatomic) BOOL runBenchmark

Declared In

TuSDKFilterProcessorBase.h

`outputImageOrientation`

This determines the rotation applied to the output image, based on the source material

@property (readwrite, nonatomic) UIInterfaceOrientation outputImageOrientation

Declared In

TuSDKFilterProcessorBase.h

`horizontallyMirrorRearFacingCamera`

These properties determine whether or not the two camera orientations should be mirrored. By default, both are NO.

@property (readwrite, nonatomic) BOOL horizontallyMirrorFrontFacingCamera , horizontallyMirrorRearFacingCamera
