ASM

To build the ASM you need the following packages:

go get github.com/klauspost/asmfmt/cmd/asmfmt
go get github.com/minio/c2goasm
go get github.com/minio/asm2plan9s

you will also need the yasm package

func Resize

func Resize(inputImage types.Image, opts ...Option) (types.Image, error)

Types

type Layout

type Layout int

const (
	HWCLayout Layout = iota
	CHWLayout
	InvalidLayout Layout = 9999
)

func LayoutString

func LayoutString(s string) (Layout, error)

LayoutString retrieves an enum value from the enum constants string name. Throws an error if the param is not part of the enum.

func LayoutValues

func LayoutValues() []Layout
