Add or Extract Images in PDF Using Spire.Cloud.PDF

Spire.Cloud.PDF provides the PdfImagesApi interface, allowing developers to handle images in PDF. This article shows you how to add an image to PDF and how to extract images from a particular page by using this API.

Example 1. Add an image to PDF

using System;
using System.IO;
using Spire.Cloud.Pdf.Sdk.Api;
using Spire.Cloud.Pdf.Sdk.Client;

namespace AddImage
{
    class Program
    {
        static String appId = "App ID";
        static String appKey = "App Key";
        static String baseUrl = "https://api.cloudxdocs.com";

        //Create a Configuration object based on App ID, App Key and base Url
        static Configuration pdfConfiguration = new Configuration(appId, appKey, baseUrl);

        //Create a PdfImagesApi object
        static PdfImagesApi pdfImagesApi = new PdfImagesApi(pdfConfiguration);
        static void Main(string[] args)
        {
            //Specify the source document name
            string name = "sample.pdf";

            //Specify the result document path
            string outPath = "output/AddImage.pdf";

            //Specify the index of the page to add image
            int pageNumber = 1;

            //Load the image file
            using (System.IO.Stream file = new FileStream("C:/Users/Administrator/Desktop/logo.png", FileMode.Open))
            {
                //Specify the x and y coordinate where the image will be added
                float x = 10;
                float y = 10;
           
                //Specify the width and height of image 
                float? width = null;
                float? height = null;

                //Specify the password, set to null if there is no password in the original document
                string password = null;

                //Specify the folder where the source document is stored
                string folder = "input";

                //Use the default storage, set to null
                string storage = null;

                //Call AddImage method to insert image to the spcified coodinate of the selected page
                pdfImagesApi.AddImage(name, outPath, pageNumber, file, x, y, width, height, folder, storage, password);
            }
        }
    }
}

        static String appKey = "App Key";
        static String baseUrl = "https://api.cloudxdocs.com";

        //Create a Configuration object based on App ID, App Key and base Url
        static Configuration pdfConfiguration = new Configuration(appId, appKey, baseUrl);

        //Create a PdfImagesApi object
        static PdfImagesApi pdfImagesApi = new PdfImagesApi(pdfConfiguration);

        static void Main(string[] args)

            //Specify the source document name
            string name = "Images.pdf";

            //Specify the output file path
            string outPath = "output/";

            //Specify the index of the page to extract image
            int pageNumber = 1;

            //Specify the password, set to null if there is no password in the original document
            string password = null;

            //Use the default storage, set to null
            string storage = null;

            //Specify the folder where the source document is stored
            string folder = "input";

            //Call ExtractImages to extract images from the specified page
            pdfImagesApi.ExtractImages(name, outPath, pageNumber, folder, storage, password);
        }
    }
