go-ico

A library for parsing and working with .ico image files. Compatible with Go’s standard image library.

NOTE: This library is not being maintained and might not fully work anymore.

Installation

go get github.com/dkua/go-ico

Dependencies

There is a single dependency on github.com/jsummers/gobmp, a library for working with .bmp files in Go. There is no builtin support for .bmp in the image package, there is an experimental library in image/x/bmp but it is not very good.

Usage

reader, err := os.Open("example.ico")
if err != nil {
        log.Fatal(err)
}
defer reader.Close()

// To decode and return the first (and usually largest) image of an .ico image
image, err := Decode(r)  // image is of image.Image type
if err != nil {
        log.Fatal(err)
}

// To decode and return all the images of an .ico image
ic, err := DecodeAll(r)  // ic is a custom ico.ICO containing an array of image.Image
if err != nil {
        log.Fatal(err)
}
