private static TextStamp WatermarkShapeSet(TextStamp textStamp)
{
// PdfWatermarkValues object is required to access needed constant values for constructing watermark
PdfWatermarkValues PWV = new PdfWatermarkValues();

textStamp.setBackground(true);
textStamp.setXIndent(PWV.textStampXIndent);
textStamp.setYIndent(PWV.textStampYIndent );
textStamp.setRotate(com.aspose.pdf.Rotation.on90);
new com.aspose.pdf.FontRepository();
textStamp.getTextState().setFont(FontRepository.findFont(PWV.textStampFont));
textStamp.getTextState().setFontSize(PWV.textStampFontSize);
textStamp.getTextState().setFontStyle(com.aspose.pdf.FontStyles.Bold);
textStamp.getTextState().setFontStyle(com.aspose.pdf.FontStyles.Italic);
textStamp.getTextState().setForegroundColor(com.aspose.pdf.Color.getGray());

The real document is test.pdf

The watermark text ="Hello Dude"
You can put any…
Means it will depend on user
Just need it in the center, rotated and transparent grey shade. Thankyou

Hi Hafsa,


Thanks for sharing the resource files.

In order to center Align the Watermark object, please specify the Vertical and Horizontal alignment as Center and specify the RotateAngle for Stamp object as 45. Please take a look over following code snippet and for your reference, I have also attached the resultant file generated over my end.

[Java]

private static TextStamp
WatermarkShapeSet(TextStamp textStamp)<o:p></o:p>

{

// PdfWatermarkValues object is required to access needed constant values for constructing watermark

//PdfWatermarkValues PWV = new PdfWatermarkValues();

textStamp.setBackground(true);

textStamp.setVerticalAlignment(com.aspose.pdf.VerticalAlignment.Center);

// textStamp.setXIndent(PWV.textStampXIndent);

// textStamp.setYIndent(PWV.textStampYIndent );

textStamp.setHorizontalAlignment(com.aspose.pdf.HorizontalAlignment.Center);

textStamp.setRotateAngle(45);

new com.aspose.pdf.FontRepository();

textStamp.getTextState().setFont(FontRepository.findFont("Arial"));

textStamp.getTextState().setFontSize(20);

textStamp.getTextState().setFontStyle(com.aspose.pdf.FontStyles.Bold);

textStamp.getTextState().setFontStyle(com.aspose.pdf.FontStyles.Italic);

textStamp.getTextState().setForegroundColor(com.aspose.pdf.Color.getGray());

return textStamp;

}

Hi Hafsa,

Please try using textStamp.setBackground(false); to display TextStamp over the front of page contents. See attached output.
