Identicon Generator
Introduction
This is a small example of a simple identicon generator written in golang, the blog post can be found here: https://www.bartfokker.nl/posts/identicon/
go get to get the package
go get github.com/lercher/identicon
This Fork
This fork introduces more control over the png image generated, adds more contrast to the chosen color and publishes its list of set pixel coordinates.
Breaking Changes
The Name field is removed, b/c it is only converted to a string from the generator byte slice,
which needs not be a string up-front.
The WriteImage method was removed and replaced by WritePNGImage with more parameters.
Added API
An identicon now publishes a slice of (X,Y) coordinates of set pixels as Pixels
Usage
import "github.com/lercher/identicon"
i := identicon.Generate([]byte("Simpson"))
// 50px per identicon pixel, i.e. 250x250 image written
// using dark colors in the byte range 0-127:
_ = i.WritePNGImage(w, 50, identicon.LightBackground(true))
log.Println(i.Pixels)

type Identicon ¶
type Identicon struct {
Pixels []Point
// contains filtered or unexported fields
}
Identicon grphically represents a hash in a 5x5 matrix
func Generate ¶
Generate creates an Identicon from an arbitrary byte array. It is garanteed that the same byte array produces the same Identicon.
func (Identicon) WritePNGImage ¶
WritePNGImage writes the identicon image to the given writer with width and height of 5 times pixwidth and LightBackground(true) or LightBackground(false) as lbg
