有没有办法用golang将PDF转换成jpeg？

go get github.com/pdfcpu/pdfcpu
go get github.com/creachadair/ghostscript

package main

import (
	"fmt"
	"log"
	"os"
	"os/exec"
	"path/filepath"
	"strings"

	"github.com/pdfcpu/pdfcpu/pkg/api"
	"github.com/pdfcpu/pdfcpu/pkg/pdfcpu"
)

func main() {
	// 输入 PDF 文件路径
	inputPDF := "input.pdf"

	// 输出 JPEG 文件路径
	outputDir := "output_images"
	err := os.MkdirAll(outputDir, os.ModePerm)
	if err != nil {
		log.Fatalf("Failed to create output directory: %v", err)
	}

	// 提取 PDF 页面为单独的 PDF 文件
	config := pdfcpu.NewDefaultConfiguration()
	err = api.ExtractPagesFile(inputPDF, outputDir, nil, config)
	if err != nil {
		log.Fatalf("Failed to extract pages from PDF: %v", err)
	}

	// 获取提取的 PDF 页面文件
	files, err := filepath.Glob(filepath.Join(outputDir, "*.pdf"))
	if err != nil {
		log.Fatalf("Failed to list extracted PDF pages: %v", err)
	}

	// 将每个 PDF 页面转换为 JPEG
	for _, file := range files {
		outputJPEG := strings.Replace(file, ".pdf", ".jpeg", 1)
		err := convertPDFToJPEG(file, outputJPEG)
		if err != nil {
			log.Fatalf("Failed to convert PDF to JPEG: %v", err)
		}
		fmt.Printf("Converted %s to %s\n", file, outputJPEG)
	}
}

func convertPDFToJPEG(inputPDF, outputJPEG string) error {
	// 使用 Ghostscript 将 PDF 转换为 JPEG
	cmd := exec.Command("gs", "-dNOPAUSE", "-dBATCH", "-sDEVICE=jpeg", "-r300", "-sOutputFile="+outputJPEG, inputPDF)
	err := cmd.Run()
	if err != nil {
		return fmt.Errorf("failed to run Ghostscript command: %v", err)
	}
	return nil
}

sudo apt-get install ghostscript

brew install ghostscript
