Declaration
Remarks
Create Rubber Stamp Annotations
The code sample below creates a Top Secret rubber stamp:
using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
// Load a document
processor.LoadDocument("..\\..\\Document.pdf");
// Access the first page properties
PdfPageFacade page = processor.DocumentFacade.Pages[0];
// Define a rubber stamp rectangle
PdfRectangle rubberStampRectangle = new PdfRectangle(663, 526, 763, 576);
// Create a rubber stamp in this rectangle
PdfRubberStampAnnotationFacade rubberStamp =
page.AddRubberStampAnnotation(rubberStampRectangle, PdfRubberStampAnnotationIconName.TopSecret);
rubberStamp.Author = "Jesse Faden";
rubberStamp.Contents = "Made in PDF Document API";
}
Create a Dynamic Rubber Stamp
Specify one of the following icon names as the PdfPageFacade.AddRubberStampAnnotation method parameter to create a dynamic rubber stamp:
| Icon Name | Rubber Stamp |
|---|---|
| DReviewed |  |
| DRevised |  |
| DApproved |  |
| DConfidential |  |
| DReceived |  |
Use the Author and ModificationDate properties to specify the author and the date displayed in the rubber stamp.
The code sample below creates a Reviewed dynamic stamp:
using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
// Load a document
processor.LoadDocument("..\\..\\Document.pdf");
// Access the first page properties
PdfPageFacade page = processor.DocumentFacade.Pages[0];
// Define a rubber stamp rectangle
PdfRectangle rubberStampRectangle = new PdfRectangle(663, 526, 763, 576);
// Create a "Top Secret" rubber stamp annotation
PdfRubberStampAnnotationFacade rubberStamp =
page.AddRubberStampAnnotation(rubberStampRectangle, PdfRubberStampAnnotationIconName.DReviewed);
rubberStamp.Author = "Jesse Faden";
}
Create an Annotation with a Custom Stamp
You can generate a stamp from another document’s page. Pass the path to a file and a page number as the PdfPageFacade.AddRubberStampAnnotation method parameters to create a custom stamp.
The code sample below generates a custom stamp from another document:
# [C#](#tab/tabid-csharp)
```csharp
using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
// Load a document
processor.LoadDocument("..\\..\\Document.pdf");
// Access the first page properties
PdfPageFacade page = processor.DocumentFacade.Pages[0];
// Define a a rubber stamp rectangle
PdfRectangle rubberStampRectangle = new PdfRectangle(663, 526, 763, 576);
// Specify a document to use as a custom stamp
string customStampFile = "..\\..\\Demo.pdf";
// Create a rubber stamp annotation
PdfRubberStampAnnotationFacade rubberStamp =
page.AddRubberStampAnnotation(rubberStampRectangle, customStampFile, 2);
rubberStamp.Author = "Jesse Faden";
// Save the result
processor.SaveDocument("..\..\Result.pdf")
}
Edit Rubber Stamp Annotations
The PdfPageFacade.Annotations property returns all page annotation properties. You can filter rubber stamp annotation properties, cast them to the PdfRubberStampAnnotationFacade class, and use class properties to modify annotation parameters.
The code sample below retrieves all rubber stamps, and changes their icon and author:
using DevExpress.Pdf;
using System.Linq;
using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
// Load a document
processor.LoadDocument("..\\..\\Document.pdf");
// Access the first page properties
PdfPageFacade page = processor.DocumentFacade.Pages[0];
// Retrieve all rubber stamp annotations
var rubberStamps = page.Annotations.Where
(annotation => annotation.Type == PdfAnnotationType.RubberStamp);
// Change rubber stamp parameters
foreach (PdfRubberStampAnnotationFacade rubberStamp in rubberStamps)
{
rubberStamp.Author = "Brian Zetc";
rubberStamp.IconName = PdfRubberStampAnnotationIconName.Confidential;
rubberStamp.Opacity = 0.5;
}
}
Flatten Rubber Stamp Annotations
Call one of the following methods to flatten an annotation:
| Method | Description |
|---|---|
| PdfDocumentFacade.FlattenAnnotations | Flattens document annotations. |
| PdfPageFacade.FlattenAnnotations | Flattens annotations of a specific page. |
| PdfAnnotationFacade.Flatten() | Flattens a specific annotation. |
The code sample below flattens all rubber stamp annotations on the first page.
using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
// Load a document
processor.LoadDocument("..\\..\\Document.pdf");
// Access the first page properties
PdfPageFacade page = processor.DocumentFacade.Pages[0];
// Flatten all rubber stamps
page.FlattenAnnotations(PdfAnnotationType.RubberStamp);
}
Remove Rubber Stamp Annotations
Call the PdfAnnotationFacade.Remove() method to remove an annotation. The code sample below removes all rubber stamps on the first page.
using DevExpress.Pdf;
using System.Linq;
using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
// Load a document
processor.LoadDocument("..\\..\\Document.pdf");
// Access the first page properties
PdfPageFacade page = processor.DocumentFacade.Pages[0];
// Retrieve all rubber stamps
var rubberStamps = page.Annotations.Where
(annotation => annotation.Type == PdfAnnotationType.RubberStamp).ToList();
// Remove all rubber stamps
foreach (PdfRubberStampAnnotationFacade rubberStamp in rubberStamps)
{
rubberStamp.Remove();
}
}
