StampAnnotation

Add stamp annotations to the PDF document

Stamp annotations are added using the annotation toolbar.

Use the Edit Annotation button in the PDF Viewer toolbar to open the annotation toolbar.
Use the Stamp Annotation drop-down to view available stamp annotation types.
Selecting a stamp type enables its annotation mode.
Place the stamp on a page in the PDF document.

NOTE

When the viewer is in pan mode and a stamp annotation tool is selected, the PDF Viewer automatically switches to text select mode to provide a smoother interaction.

The following examples show how to switch to stamp annotation modes.

Add a custom stamp

Use the Edit Annotation button and the Stamp Annotation drop-down to access the Custom Stamp option.

CustomStamp

Select the Custom Stamp option, then choose an image file to add as a custom stamp on the PDF page.

Only JPG and JPEG image formats are supported for custom stamp annotations.

Add a stamp annotation programmatically

Use the addAnnotation() method to add stamp annotations programmatically.

The examples below demonstrate using addAnnotation() to create stamp annotations.

Set default properties during control initialization

Set default properties for stamp annotations before creating the control by specifying stampSettings.

After changing the default opacity using the Edit Opacity tool, the selected value is applied. The example below shows how to set default stamp annotation settings.
