Functions

func ColorReliefImage

func ColorReliefImage(img image.Image, gm *gradientMap) (image.Image, error)

func Execute

func Execute()

Execute adds all child commands to the root command and sets flags appropriately. This is called by main.main(). It only needs to happen once to the rootCmd.

func HillshadeImage

func HillshadeImage(img image.Image,
	pixel_res float64,
	h_factor float64,
	altitude float64,
	azimuth float64) (image.Image, error)

func MustParseHex

func MustParseHex(s string) colorful.Color

func NewGradientMap

func NewGradientMap(colorCard []colorCard, heighPrecision float64) (*gradientMap, error)

func NewTerra

func NewTerra(cfg aws.Config, s3Config s3Config) (*terra, error)

func TransparentGrayscale

func TransparentGrayscale(img image.Image) image.Image
