Remarks

The following code sample demonstrates how the FromFile method can be used to insert an image:

C#

using DevExpress.BarCodes;
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;

using (var wordProcessor = new RichEditDocumentServer()) {
    wordProcessor.LoadDocument("Texts\\Pictures.docx");
    Document doc = wordProcessor.Document;

    // Insert an image from a file.
    DocumentRange rangeFound = doc.FindAll("Visual Studio Magazine", SearchOptions.CaseSensitive)[0];
    DocumentPosition pos = doc.Paragraphs[doc.Paragraphs.Get(rangeFound.End).Index + 2].Range.Start;
    doc.Shapes.InsertPicture(pos, DocumentImageSource.FromFile("Pictures\\ReadersChoice.png"));
}

VB.NET

Imports DevExpress.BarCodes
Imports DevExpress.XtraRichEdit
Imports DevExpress.XtraRichEdit.API.Native

Using wordProcessor = New RichEditDocumentServer()
  wordProcessor.LoadDocument("Texts\Pictures.docx")
  Dim doc As Document = wordProcessor.Document

  ' Insert an image from a file.
  Dim rangeFound As DocumentRange = doc.FindAll("Visual Studio Magazine", SearchOptions.CaseSensitive)(0)
  Dim pos As DocumentPosition = doc.Paragraphs(doc.Paragraphs.Get(rangeFound.End).Index + 2).Range.Start
  doc.Shapes.InsertPicture(pos, DocumentImageSource.FromFile("Pictures\ReadersChoice.png"))
End Using

Note

When you use theFromFile method to create an image, the method locks the file until the application is closed. This happens because the method internally creates a file stream intended to load the image from the file, which is not disposed of together with the RichEditDocumentServer/RichEditControl instance and stays alive until you close the application.

If you require releasing the file while the program is running, you can use the DocumentImageSource.FromStream method to create an image and close the stream manually after the image is inserted into the document.
