See https://en.wikipedia.org/wiki/ICO_(file_format) for more information.
Installation
Use go get:
go get github.com/sergeymakinen/go-ico
Then import the package into your own code:
import "github.com/sergeymakinen/go-ico"
Example
b, _ := os.ReadFile("icon_32x32-32.png")
m1, _ := png.Decode(bytes.NewReader(b))
b, _ = os.ReadFile("icon_256x256-32.png")
m2, _ := png.Decode(bytes.NewReader(b))
f, _ := os.Create("icon.ico")
ico.EncodeAll(f, []image.Image{m1, m2})
f.Close()

Functions ¶
func Decode ¶
Decode reads an ICO image from r and returns the largest stored icon as an image.Image.
func DecodeConfig ¶
DecodeConfig returns the color model and dimensions of the largest icon stored in an ICO image without decoding the entire icon.

type FormatError ¶
type FormatError string
FormatError reports that the input is not a valid ICO.
func (FormatError) Error ¶
func (e FormatError) Error() string
type UnsupportedError ¶
type UnsupportedError string
UnsupportedError reports that the input uses a valid but unimplemented ICO feature.
func (UnsupportedError) Error ¶
func (e UnsupportedError) Error() string
