go-ppic

Profile picture generation service written in Go. A demo can be found at go-ppic.herokuapp.com.

go-ppic provides two commands; ppicd and ppic.

ppicd

ppicd is a web server providing image generation.

Installation

go get -u github.com/jackwilsdon/go-ppic/cmd/ppicd

Usage

  -d	enable pprof debug routes
  -h string
    	host to run the server on
  -p uint
    	port to run the server on (default 3000)
  -v	enable verbose output
  -z	enable gzip compression

After starting up the server, you should see something similar to the following output;

2006/01/02 15:04:05 starting server on http://127.0.0.1:3000...

Visiting the URL that the server is running on will give you the image for an empty string. You can get the image for the string "example" by visiting /example on the server (http://127.0.0.1:3000/example in this case).

URL Parameters

The server accepts the following query parameters to change the response;

  • ?size=N → specify the size of the image to return (must be a multiple of 8)
  • ?monochrome → change the image to black and white

Supported Extensions

By default the server will respond in PNG format, but it also supports the following file extensions;

  • .gif
  • .jpeg

ppic

ppic is used to generate profile pictures on the command line, without having to run a web server. ppic outputs the generated image to stdout.

Installation

go get -u github.com/jackwilsdon/go-ppic/cmd/ppic

Usage

usage: ppic text [size] > image.png

size defaults to 512 if not provided

Examples

ppic jackwilsdon 1024 > profile.png
