通过 Go SDK 解析 PDF 以按 Id 提取图像

package main

import (
	"fmt"
	"path"

	asposepdfcloud "github.com/aspose-pdf-cloud/aspose-pdf-cloud-go/v25"
)

// Extract Image from the document to PNG file
func ParseExtractImage(documentName string, imageId string, localFolder string, remoteFolder string) {
	
	// Get your AppSecret and Key from https://dashboard.aspose.cloud (free registration required).
	pdf_api := asposepdfcloud.NewPdfApiService(APP_SID, APP_KEY, "")

	args := map[string]interface{}{
		"folder": remoteFolder,
	}

	file, _ := os.Open(path.Join(localFolder, documentName))	
	_, _, _ = pdf_api.UploadFile(path.Join(remoteFolder, documentName), file, args)

	response, httpResponse, err := pdf_api.GetImageExtractAsPng(documentName, imageId, args)

	if err != nil {
		fmt.Println(err.Error())
	} else if httpResponse.StatusCode < 200 || httpResponse.StatusCode > 299 {
		fmt.Println("ParseExtractImage(): Failed to extract image.")
	} else {

		fileName := path.Join(localFolder, (imageId + ".png"))
		f, _ := os.Create(fileName)
		_, _ = f.Write(response)
		fmt.Println("File '" + fileName + "' successfully downloaded.")
	}
