Convert Word document to HTML is popular and widely used by programmers and developers. With the help of Spire.Doc for .NET, a professional word component, without installing MS Word, developers can convert word to html with only two lines of key code in C#. At the same time, Spire.Doc supports convert HTML to word document easily and quickly.

This article still focuses on convert word from/to HTML, while it mainly about the supports of embed image in the word document and HTML. With the improvements of Spire.Doc (starts from Spire.Doc V. 4.9.32), now it supports the new function of ImageEmbedded.

Please download Spire.Doc (version 4.9.32 or above) with .NET framework together and follow the simple steps as below:

Convert Word to HTML in C#:

Step 1: Create the word document.

Document document = new Document();

Step 2: Set the value of imageEmbedded attribute.

doc.HtmlExportOptions.ImageEmbedded=true;

Step 3: Save word document to HTML.

doc.SaveToFile("result.html",FileFormat.Html);

Spire.Doc also supports load the result HTML page and convert it into word document in only three lines of codes as below.

doc.SaveToFile("htmltoword.docx",FileFormat.Docx);

Besides conversion of word from/to HTML, Spire.Doc also supports Convert Word to PDF, Convert Word to Image and Convert Word to XPS in C#.

For the function of converting image to PDF, Spire.PDF can handle it quickly and effectively. This .NET PDF library can not only convert images of commonly used formats to PDF document such as jpg, bmp, png, but also convert gif, tif and ico images to PDF. Just download it here.

To convert multipage image to a PDF file with Spire.PDF, just copy the following code to your application and call method ConvertImagetoPDF and you will get it done.

Step 1: Method to split multipage image

Spire.Pdf has a method called DrawImage to convert image to PDF. But it cannot handle multipage image directly. So before conversion, multipage image need to be split into several one-page images.

Guid guid = image.FrameDimensionsList[0];
FrameDimension dimension = new FrameDimension(guid);
int pageCount = image.GetFrameCount(dimension);

This step is to get the total number of frames (pages) in the multipage image.

image.SelectActiveFrame(dimension, i);

And this step is to select one frame of frames within this image object.

image.Save(buffer, format);

Save the selected frame to the buffer.

Step 2: Convert image to PDF

After splitting multipage image, Spire.Pdf can draw these split images directly to PDF using method DrawImage.

PdfImage pdfImg = PdfImage.FromImage(img[i])

Load image file as PdfImage.

page.Canvas.DrawImage(pdfImg, x, 0, width, height);

Draw PdfImage to PDF. The only thing to do is to specify the location of image on PDF. Width and height is the size of area that image will be drawn on. Sometimes we need to scale up or down the size of the original size of image until it fit the PDF page. x and 0 locate the coordinate.

The article will introduce an easy way to convert Word to Emf by a powerful and independent Word .NET component called Spire.Doc, without Microsoft Word installed on the machine. It also offers support for converting Word and HTML to frequently-used image formats like Jpeg, Png, Gif, Bmp and Tiff, etc. Just click here to have a try.

Emf is a file extension for Enhanced MetaFile, used as a graphics language for printer drivers by the Windows operating system. In 1993, a newer version with additional commands 32-bit version of Win32/GDI introduced the Enhanced Metafile (Emf). Microsoft also recommends enhanced-format (Emf) functions to be used instead of rarely being used Windows-format (WMF) functions.

Spire.Doc presents almost the easiest solution to convert Word to Emf through the following 5 lines simple code.

using Spire.Doc;
using System.Drawing.Imaging;


namespace DOCEMF
{
    class Program
    {
        static void Main(string[] args)
        {
            // create an instance of Spire.Doc.Document
            Document doc = new Document();
            // load the file base on a specified file name
            doc.LoadFromFile(@"../../Original Word.docx", FileFormat.Docx);
            //convert the first page of document to image
            System.Drawing.Image image = doc.SaveToImages(0, Spire.Doc.Documents.ImageType.Metafile);
            // save the document object to Emf file
            image.Save(@"../../Convert Word to Image.emf", ImageFormat.Emf);
            //close the document
            doc.Close();

        }
    }
}

Spire.DataExport is a completely pure .NET component suit for exporting data into MS Excel, MS Word, HTML, Office OpenXML, PDF, MS Access, DBF, RTF, SQL Script, SYLK, DIF, CSV, MS Clipboard format. It has high performance for exporting data from Command, ListView, DataTable components, which help you to save much time and money.

Please download Spire.DataExport for .NET, add Spire.DataExport.dll as reference and set its target framework as .NET 4. Besides, many developers also check and download another C# excel component together - Spire.XLS for .NET.

Step1: Function to fill data in datatable

In this step, Spire.DataExport will help to load Data information from the datatable. After setting up the data source and SQL command, we can even preview and modify data through DataGridVew 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;
            }
        }

Check the Screenshot below:

Step2: Export Data to Office OpenXML

The code below shows how to export data from the datatable to Office OpenXML. Spire.DataExport will create a new Office OpenXML and export data into Office OpenXML through DataGridView. It also allows you to rename the generated Office OpenXML in this step.

private void btnExportToXml_Click(object sender, EventArgs e)
        {
            Spire.DataExport.XML.XMLExport xmlExport = new Spire.DataExport.XML.XMLExport();
            xmlExport.DataSource = Spire.DataExport.Common.ExportSource.DataTable;
            xmlExport.DataTable = this.dataGridView1.DataSource as DataTable;
            xmlExport.ActionAfterExport = Spire.DataExport.Common.ActionType.OpenView;
            xmlExport.FileName = @"..\..\ToXml.xml";
            xmlExport.SaveToFile();
        }

Extracting images from PDFs is a common task for many users, whether it's for repurposing visuals in a presentation, archiving important graphics, or facilitating easier analysis. By mastering image extraction using C#, developers can enhance resource management and streamline their workflow.

In this article, you will learn how to extract images from individual PDF pages as well as from entire documents using C# and Spire.PDF for .NET.

• Extract Images from a Specific PDF Page
• Extract All Images from an Entire PDF Document

Install Spire.PDF for .NET

To begin with, you need to add the DLL files included in the Spire.PDF for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

PM> Install-Package Spire.PDF

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.

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.

Set .NET 4 as target framework

Step 2: Instance an object of Spire.PdfViewer.Wpf.PdfDocumentViewer

PdfDocumentViewer pdfViewer = new PdfDocumentViewer();

Step 3: Call the “LoadFromFile”of PdfDocumentViewer object and load a PDF file.

pdfViewer.LoadFromFile ("sample.pdf");

Step 4: Create an array and save all pages of this PDF file.

int[] pageNumbers=new int[pageCount];
            for (int i=0;i

Step 5: Save it to Tiff image format

pdfViewer.SaveAsImage("sample.tiff",pageNumbers);

The following code snippet shows all the code when converting pdf page to tiff image:

private void Button_Click(object sender, RoutedEventArgs e)
        {
            // Instance an object of Spire.PdfViewer.Wpf.PdfDocumentViewer
            PdfDocumentViewer pdfViewer = new PdfDocumentViewer();
            //Load a pdf file 
            pdfViewer.LoadFromFile("sample.pdf");
            int pageCount = pdfViewer.PageCount;
            // create an array and save all pages of this PDF file.
            int[] pageNumbers=new int[pageCount];
            for (int i=0;i

XPS is a format similar to PDF but uses XML in layout, appearance and printing information of a file. XPS format was developed by Microsoft and it is natively supported by the Windows operating systems. If you want to work with your PDF files on a Windows computer without installing other software, you can convert it to XPS format. Likewise, if you need to share a XPS file with a Mac user or use it on various devices, it is more recommended to convert it to PDF. This article will demonstrate how to programmatically convert PDF to XPS or XPS to PDF using Spire.PDF for .NET.
