WatermarkManager.SetImage(Image, ImageWatermarkOptions) Method

Adds an image watermark to all document pages.

Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v24.2.Core.dll

NuGet Package: DevExpress.RichEdit.Core

Declaration

C#

[Browsable(false)]
void SetImage(
    Image image,
    ImageWatermarkOptions options
)

VB.NET

<Browsable(False)>
Sub SetImage(
    image As Image,
    options As ImageWatermarkOptions
)

Parameters

Name	Type	Description
image	Image	A watermark image.
options	ImageWatermarkOptions	An object that contains image watermark options.

Remarks

Watermarks are located in section headers. If a document does not contain headers, a SetImage method call adds headers of the Primary type to all document sections.

If the document has multiple sections, this method adds the same watermark to each section and each existing section header (first, primary, odd, or even).

The WatermarkManager.Type property indicates whether the document has watermarks. The property returns WatermarkType.None if the document does not contain watermarks.

Example

The code sample below adds an image watermark to all document pages.

C#

using (RichEditDocumentServer wordProcessor = new RichEditDocumentServer())
{
    wordProcessor.LoadDocument("DocumentProtection.docx");

    ImageWatermarkOptions imageWatermarkOptions = new ImageWatermarkOptions();
    imageWatermarkOptions.Washout = false;
    imageWatermarkOptions.Scale = 1.5;

    wordProcessor.Document.WatermarkManager.SetImage(Image.FromFile("DevExpress.png"), imageWatermarkOptions);
    wordProcessor.SaveDocument("DocumentProtection_new.docx", DocumentFormat.OpenXml);
}

VB.NET

Using wordProcessor As New RichEditDocumentServer()
    wordProcessor.LoadDocument("DocumentProtection.docx")

    Dim imageWatermarkOptions As New ImageWatermarkOptions()
    imageWatermarkOptions.Washout = False
    imageWatermarkOptions.Scale = 1.5

    wordProcessor.Document.WatermarkManager.SetImage(Image.FromFile("DevExpress.png"), imageWatermarkOptions)
    wordProcessor.SaveDocument("DocumentProtection_new.docx", DocumentFormat.OpenXml)
End Using
