Functions

func ConvertBGRAToYCbCrImage

func ConvertBGRAToYCbCrImage(
	bgra *imgext.BGRA,
) (*image.YCbCr, error)

ConvertBGRAToYCbCrImage see ConvertImageToYCbCrImage

func ConvertBGRAToYCbCrImageIPP

func ConvertBGRAToYCbCrImageIPP(
	bgra *imgext.BGRA,
) (*image.YCbCr, error)

ConvertBGRAToYCbCrImageIPP will use IPP intel API to convert imgext.BGRA image into image.YCbCr

func ConvertBGRAToYCbCrImageStandard

func ConvertBGRAToYCbCrImageStandard(
	bgra *imgext.BGRA,
) (*image.YCbCr, error)

ConvertBGRAToYCbCrImageStandard will use Go native color.RGBToYCbCr()

func ConvertImageToYCbCrImage

func ConvertImageToYCbCrImage(
	img image.Image,
) (*image.YCbCr, error)

ConvertImageToYCbCrImage will try use the most fast algorithm for input image.RGBA or imgext.BGRA Use IPP intel API unaligned to convert image into YCbCr on amd64 Use SSE intel API unaligned to convert image into YCbCr on amd64 if IPP not available if above algorithm not available, Go native standard color.RGBToYCbCr() is used

func ConvertRGBAToYCbCrImage

func ConvertRGBAToYCbCrImage(
	rgba *image.RGBA,
) (*image.YCbCr, error)

ConvertRGBAToYCbCrImage see ConvertImageToYCbCrImage

func ConvertRGBAToYCbCrImageSSEUnaligned

func ConvertRGBAToYCbCrImageSSEUnaligned(
	rgba *image.RGBA,
) (*image.YCbCr, error)

ConvertRGBAToYCbCrImageSSEUnaligned will use SSE intel API unaligned to convert RGBA image into YCbCr

func ConvertRGBAToYCbCrImageStandard

func ConvertRGBAToYCbCrImageStandard(
	rgba *image.RGBA,
) (*image.YCbCr, error)

ConvertRGBAToYCbCrImageStandard will use Go native color.RGBToYCbCr()
