用go语言创建图片，并在图片上写汉字

image.go

package main

import (
	_ "embed"
	"github.com/golang/freetype"
	"github.com/golang/freetype/truetype"
	"golang.org/x/image/math/fixed"
	"image"
	"image/color"
	"image/draw"
	"image/png"
	"os"
)

//go:embed SourceHanSansCN-Normal.ttf
var myFont []byte

func main() {
	img := image.NewRGBA(image.Rect(0, 0, 320, 100))
	bg := color.RGBA{255, 255, 255, 255}
	red := color.RGBA{255, 0, 0, 255}
	draw.Draw(img, img.Bounds(), &image.Uniform{bg}, image.Point{}, draw.Src)
	font, err := truetype.Parse(myFont)
	if err != nil {
		panic(err)
	}
	ctx := freetype.NewContext()
	ctx.SetClip(img.Bounds())
	ctx.SetSrc(&image.Uniform{red})
	ctx.SetDst(img)
	ctx.SetFont(font)
	ctx.SetFontSize(80.0)
	if _, err := ctx.DrawString("你好世界", fixed.P(0, 80)); err != nil {
		panic(err)
	}
	f, err := os.Create("draw.png")
	if err != nil {
		panic(err)
	}
	defer f.Close()
	png.Encode(f, img)
}
