Method Documentation

copyPixelBuffer

- (CVPixelBufferRef) copyPixelBuffer

implementation

Copy the contents of the texture into a CVPixelBuffer.

The type of the pixel buffer is one of the following:

• kCVPixelFormatType_32BGRA
• kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange
• kCVPixelFormatType_420YpCbCr8BiPlanarFullRange

Reimplemented from <FlutterTexture>.

  return [self pixelBuffer];
}

initWidth:height:pixelFormatType:

- (nonnull instancetype) initWidth:		(size_t)	width
height:		(size_t)	height
pixelFormatType:		(OSType)	pixelFormatType
