Functions

func ImgToPix

func ImgToPix(src *image.NRGBA) []uint8

ImgToPix converts an image to an 1D uint8 pixel array. In order to preserve the color information per pixel we need to reconstruct the array to a specific format.

func LoadImage

func LoadImage(path string) (string, error)

LoadImage load the source image and encodes it to base64 format.

func PixToImage

func PixToImage(pixels []uint8, rect image.Rectangle) image.Image

PixToImage converts the pixel data to an image.

func RgbaToGrayscale

func RgbaToGrayscale(data []uint8, dx, dy int) []uint8

RgbaToGrayscale converts the pixel data to grayscale mode.

func RotateImg

func RotateImg(img *image.NRGBA, angle float64) []uint8

RotateImg rotates the image per pixel level to a certain degree and returns an image data.
