Program Guide for WPF (24)
With the help of Spire.Doc for WPF, developers can create and edit word documents easily and flexibly for their WPF applications. Sometimes developers need to protect their word documents for being read and edit by others. They may need to add password for the word files to protect them confidential. Then others have to enter the password to open the view the encrypted word documents. Spire.Doc for WPF offers a method of Document.Encrypt(); to enable developers to set the password for word documents and Document.RemoveEncryption(); to remove the encryption for word documents.
This article will demonstrate how to encrypt and word documents with password and decrypt the word documents in C# for WPF applications.
Note: Before Start, please download the latest version of Spire.Doc and add Spire.Doc.Wpf.dll in the bin folder as the reference of Visual Studio.
Here comes to the code snippets:
Step 1: Create a new word document and load the document from file.
Document document = new Document();
document.LoadFromFile("Sample.docx");
Step 2: Encrypt the document with password.
document.Encrypt("eiceblue");
Step 3: Save the encrypted document to file.
document.SaveToFile("Encryption.docx", FileFormat.Docx);
Step 4: Create a second new word document and load the encrypted document from file with the password.
Document document2 = new Document();
document2.LoadFromFile("Encryption.docx",FileFormat.Docx,"eiceblue");
Step 5: Decrypted the word document.
document2.RemoveEncryption();
Step 6: Save the decrypted document to file.
document2.SaveToFile("Decrytion.docx", FileFormat.Docx);
Please check the effective screenshots of the encrypted word document and the decrypted word documents as below:

In some circumstances, we may need to convert or save Word documents as pictures. For one reason, a picture is difficult to edit; for another, compared with Word, pictures are much easier to be published for browsing. This article is aimed to explore how we can convert .doc/.docx to popular image formats such as Jpg, Png, Gif and Bmp in WPF using Spire.Doc.
Spire.Doc for WPF, as a professional Word component, provides a plenty of useful methods to manipulate Word documents in your WPF applications. Using Spire.Doc, developers are able to export Word documents as images with high quality. Here comes the method:
Step 1: Create a new project by choosing WPF Application in Visual Studio, add a button in MainWindow, double click the button to write code.
public partial class MainWindow : Window
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
}
Step 2: Initialize a new instance of Spire.Doc.Document class and load the sample Word file.
Document doc = new Document("sample.docx", FileFormat.Docx2010);
Step 3: To convert Word to image in WPF, we need firstly save Word as BitmapSource by calling the method Document.SaveAsImage(ImageType type), then convert BitmapSource to Bitmap, then save the Bitmap as image with a specified format using Image.Save(). Here, I saved Bitmap as .Png.
BitmapSource[] bss = doc.SaveToImages(ImageType.Bitmap);
for (int i = 0; i < bss.Length; i++)
{
SourceToBitmap(bss[i]).Save(string.Format("img-{0}.png", i));
}
}
private Bitmap SourceToBitmap(BitmapSource source)
{
Bitmap bmp;
using (MemoryStream ms = new MemoryStream())
{
PngBitmapEncoder encoder = new PngBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(source));
encoder.Save(ms);
bmp = new Bitmap(ms);
}
return bmp;
}
