我试图将mp3文件转换为wav文件,但我不知道如何做到这一点,我尝试使用fluent-ffmpeg库,但我不知道如何使用它.

我有以下代码片段，例如

package main

import (
    "github.com/ajstarks/svgo"
    "os"
    _ "image"
    _ "fmt"
)

func main(){
    width := 512
    height := 512

    canvas := svg.New(os.Stdout)
    canvas.Start(width,height)
    canvas.Image(0,0,512,512,"src.jpg","0.50")
    canvas.End()
}

我想将由此代码创建的 svg 导出为 jpeg 或 png 或 svg 比方说。如何做到这一点我不明白。我可以使用 imagemagick 或其他东西，但为此我需要 SVG 的东西。请有人帮我解决这个问题。
