Go语言快速制作动图

先看效果：

好像也没谁用Golang写图像处理算法的。所以自己写了两个库：

go get github.com/CuteReimu/colortools
go get github.com/CuteReimu/neuquant

使用用法非常简单，代码如下：

package main

import (
	"github.com/CuteReimu/colortools"
	"github.com/CuteReimu/neuquant"
	"image"
	"image/color"
	"image/gif"
	"image/jpeg"
	"os"
)

func main() {
	f, _ := os.Open("1.jpg")
	defer func() { _ = f.Close() }()
	img, _ := jpeg.Decode(f)
	result := &gif.GIF{}
	for j := 0; j < 360; j += 30 {
		c := make([]color.Color, 361)
		p := make([]float64, 361)
		for i := 0; i <= 360; i++ {
			c[i] = &colortools.HSV{H: float64(i + j), S: 1.0, V: 0.5}
			p[i] = float64(i) / 360.0
		}
		img1 := colortools.NewLineGradChgColorImage(img.Bounds(), c, p, img.Bounds())
		img2 := colortools.Screen(img1, img)

		nq, palette := neuquant.AnalyzePalette(img2)
		img3 := image.NewPaletted(img2.Bounds(), palette)
		neuquant.ParallelWritePalette(nq, img2, img3)

		result.Image = append(result.Image, img3)
		result.Delay = append(result.Delay, 10)
	}
	f2, _ := os.Create("1.gif")
	defer func() { _ = f2.Close() }()
	_ = gif.EncodeAll(f2, result)
}

然后就可以把左边的原图变成右边的动图了。
