Creating a watermark from lower left corner to upper right corner

[Shane Scholl]

Hello,

Im looking for ways to manipulate the Watermark feature, either with repeating the watermark on the page, numerous times or by stretching the watermark from the bottom left corner to the top right corner and increasing the size. 

Thank you,

Shane

Hi Shane, 

 

Thank you for contacting Syncfusion support.

Yes. We can draw the watermark from the bottom left corner to the top right corner and increasing the font size using PDF library. Please find the below code snippet to achieve your requirement. 

 

//Load the PDF document 

            PdfLoadedDocument loadedDocument = new PdfLoadedDocument("../../TableFeatures.pdf"); 

 

            //Set the font 

            PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 50); 

 

            foreach (var page in loadedDocument.Pages) 

            { 

                //Get the loaded page 

                PdfLoadedPage loadedPage = page as PdfLoadedPage; 

 

                //Create graphics  

                PdfGraphics graphics = loadedPage.Graphics; 

 

                //Draw watermark text 

                PdfGraphicsState state = graphics.Save(); 

                graphics.SetTransparency(0.25f); 

                graphics.RotateTransform(-55); 

 

                graphics.DrawString("Imported using Essential PDF Syncfusion", font, PdfPens.Red, PdfBrushes.Red, new PointF(-640, 460)); 

 

                graphics.Restore(); 

            } 

 

            //Save and close the document 

            loadedDocument.Save("../../Watermark.pdf"); 

            loadedDocument.Close(true);
