There are some requirements to export datatable or dataset to word file on many occasions at work. The aim of this article is to help you complete this requirement. Spire.DataExport can help easily load data from the datatable and create a new Word file for storing the data. In addition to this, Spire.DataExport (or Spire.Office) can export data into MS Excel, HTML, XML, PDF, MS Access, DBF, SQL Script, SYLK, DIF, CSV and MS Clipboard format as well, which can be downloaded here. The following code is the example of showing how Spire.DataExport works.

Step 1: Function to fill data in datatable

In this step, Spire.DataExport will help load Data information from the datatable. After setting up the data source and SQL command, it allows you to preview and edit data in DataGridView component before exporting.

private void Form1_Load(object sender, EventArgs e)
        {
            oleDbConnection1.ConnectionString = txtConnectString.Text;
            oleDbCommand1.CommandText = txtCommandText.Text;
            using (OleDbDataAdapter da = new OleDbDataAdapter())
            {
                da.SelectCommand = oleDbCommand1;
                da.SelectCommand.Connection = oleDbConnection1;
                DataTable dt = new DataTable();
                da.Fill(dt);
                dataGridView1.DataSource = dt;
            }
        }

Extract Images from a Specific PDF Page

The PdfImageHelper class in Spire.PDF for .NET is designed to help users manage images within PDF documents. It allows for various operations, such as deleting, replacing, and retrieving images.

To obtain information about the images on a specific PDF page, developers can utilize the PdfImageHelper.GetImagesInfo(PdfPageBase page) method. Once they have the image information, they can save the images to files using the PdfImageInfo.Image.Save() method.

The steps to extract images from a specific PDF page are as follows:

• Create a PdfDocument object.
• Load a PDF file using PdfDocument.LoadFromFile() method.
• Get a specific page using PdfDocument.Pages[index] property.
• Create a PdfImageHelper object.
• Get the image information collection from the page using PdfImageHelper.GetImagesInfo() method.
• Iterate through the image information collection and save each instance as a PNG file using PdfImageInfo.Image.Save() method.

using Spire.Pdf;
using Spire.Pdf.Utilities;
using System.Drawing;

namespace ExtractImagesFromSpecificPage
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create a PdfDocument object
            PdfDocument doc = new PdfDocument();

            // Load a PDF document
            doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.pdf");

            // Get a specific page
            PdfPageBase page = doc.Pages[0];

            // Create a PdfImageHelper object
            PdfImageHelper imageHelper = new PdfImageHelper();

            // Get all image information from the page 
            PdfImageInfo[] imageInfos = imageHelper.GetImagesInfo(page);

            // Iterate through the image information
            for (int i = 0; i < imageInfos.Length; i++)
            {
                // Get a specific image information
                PdfImageInfo imageInfo = imageInfos[i];

                // Get the image
                Image image = imageInfo.Image;

                // Save the image to a png file
                image.Save("C:\\Users\\Administrator\\Desktop\\Extracted\\Image-" + i + ".png");
            }

            // Dispose resources
            doc.Dispose();
        }
    }
}

Extract All Images from an Entire PDF Document

Now that you know how to extract images from a specific page, you can iterate through the pages in a PDF document and extract images from each page. This allows you to collect all the images contained in the document.

The steps to extract all images throughout an entire PDF document are as follows:

• Create a PdfDocument object.
• Load a PDF file using PdfDocument.LoadFromFile() method.
• Create a PdfImageHelper object.
• Iterate through the pages in the document.
  • Get a specific page using PdfDocument.Pages[index] property.
  • Get the image information collection from the page using PdfImageHelper.GetImagesInfo() method.
  • Iterate through the image information collection and save each instance as a PNG file using PdfImageInfo.Image.Save() method.

using Spire.Pdf;
using Spire.Pdf.Utilities;
using System.Drawing;

namespace ExtractAllImages
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create a PdfDocument object
            PdfDocument doc = new PdfDocument();

            // Load a PDF document
            doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.pdf");

            // Create a PdfImageHelper object
            PdfImageHelper imageHelper = new PdfImageHelper();

            // Declare an int variable
            int m = 0;

            // Iterate through the pages
            for (int i = 0; i < doc.Pages.Count; i++)
            {
                // Get a specific page
                PdfPageBase page = doc.Pages[i];

                // Get all image information from the page 
                PdfImageInfo[] imageInfos = imageHelper.GetImagesInfo(page);

                // Iterate through the image information
                for (int j = 0; j < imageInfos.Length; j++)
                {
                    // Get a specific image information
                    PdfImageInfo imageInfo = imageInfos[j];

                    // Get the image
                    Image image = imageInfo.Image;

                    // Save the image to a png file
                    image.Save("C:\\Users\\Administrator\\Desktop\\Extracted\\Image-" + m + ".png");
                    m++;
                }

            }

            // Dispose resources
            doc.Dispose();
        }
    }
}

Background

PDF is now widely used to represent document in independent specification. It encapsulates a complete description of a fixed-layout flat document, including the text, fonts and graphics and so on. Due to its powerful functions, it is difficult for developers to parse its format. Or more specifically, to parse content out from PDF document and convert it to different image format is a tough task for some developers. This article will help you solve this problem by using PDF document viewer component Spire.PDFViewer for WPF by 5 easy steps. Firstly, you can download Spire.PDFViewer for WPF.

Target

To convert a specified or random page including frames of images from PDF file to TIFF programmatically.

Step 1: To create WPF application in Visual Studio and reference Spire.PdfViewer.WPF dlls.
