SVG example

This is a hello world for rendering SVG images with gd. The output in this README is derived from running example.go with gd example.go >README.md.

package main

import (
	"io"
	"log"
	"net/http"
	"strings"

The "show" package is a magic package that is resolved by the gd build tool. The full path may also be used, then it would be "github.com/kortschak/gd/show".

	"show"
)

func main() {
	resp, err := http.Get("https://raw.githubusercontent.com/gonum/gonum/master/gopher.svg")
	if err != nil {
		log.Fatal(err)
	}
	var buf strings.Builder
	_, err = io.Copy(&buf, resp.Body)
	if err != nil {
		log.Fatal(err)
	}
	show.SVG(buf.String(), "gopher", "Gonum Gopher")
