Functions

func AsRGBA

func AsRGBA(src image.Image) *image.RGBA

AsRGBA returns an RGBA copy of the supplied image.

func AsShallowRGBA

func AsShallowRGBA(src image.Image) *image.RGBA

AsShallowRGBA tries to cast to image.RGBA to get reference. Otherwise makes a copy

func Pad

func Pad(src image.Image, padX, padY int, m PadMethod) *image.RGBA

Pad returns an RGBA copy of the src image parameter with its edges padded using the supplied PadMethod. Parameter padX and padY correspond to the amount of padding to be applied on each side. Parameter m is the PadMethod to fill the new pixels.

Usage example:

result := Pad(img, 5,5, EdgeExtend)

Types

type PadMethod

type PadMethod uint8

PadMethod is the method used to fill padded pixels.
