 ## Adding text watermark in PDF document
 
-The below code illustrates how to draw the text watermark in new PDF document using [DrawString](https://help.syncfusion.com/cr/document-processing/Syncfusion.Pdf.Graphics.PdfGraphics.html#Syncfusion_Pdf_Graphics_PdfGraphics_DrawString_System_String_Syncfusion_Pdf_Graphics_PdfFont_Syncfusion_Pdf_Graphics_PdfPen_Syncfusion_Pdf_Graphics_PdfBrush_System_Drawing_PointF_) method of [PdfGraphics](https://help.syncfusion.com/cr/document-processing/Syncfusion.Pdf.Graphics.PdfGraphics.html) class. The transparency can be applied to the text or images using [SetTransparency](https://help.syncfusion.com/cr/document-processing/Syncfusion.Pdf.Graphics.PdfGraphics.html#Syncfusion_Pdf_Graphics_PdfGraphics_SetTransparency_System_Single_) method and rotation can be applied using [RotateTransform](https://help.syncfusion.com/cr/document-processing/Syncfusion.Pdf.Graphics.PdfGraphics.html#Syncfusion_Pdf_Graphics_PdfGraphics_RotateTransform_System_Single_) method.

+The [PdfGraphicsState](https://help.syncfusion.com/cr/document-processing/Syncfusion.Pdf.Graphics.PdfGraphicsState.html) class is used to save the current graphics context of a PdfGraphics object. This includes properties like transformations, transparency settings, clipping paths, and other graphical configurations. By calling `graphics.Save()`, you store the current state before applying changes such as rotation or transparency. Later, you can restore this state using `graphics.Restore(state)` to revert to the original settings, ensuring that temporary modifications do not affect subsequent drawing operations. This is especially useful when adding watermarks, as it allows you to isolate the watermark styling from other content on the page.
