Water mark overlaps the Text in PDF

[kumarjasper]

Hi

i am trying to get the waternark on my pdf. But the water mark overlaps the Text on PDF.But i want the water mark to be translucent. i m using the below code to get watermark on PDF.

 

public byte[] addWatermark(byte[] bytes) {

ByteArrayOutputStream bos = new ByteArrayOutputStream();

try {

PdfReader reader = new PdfReader(bytes);

int n = reader.getNumberOfPages();

PdfStamper stamp = new PdfStamper(reader, bos);

int i = 0;

PdfContentByte under;

BaseFont bf = BaseFont.createFont(BaseFont.HELVETICA,BaseFont.WINANSI, BaseFont.EMBEDDED);

while (i < n) {

i++;

under = stamp.getUnderContent(i);

under.setGrayFill(0.9f);

under.beginText();

under.setFontAndSize(bf, 40);

under.showTextAligned(PdfContentByte.ALIGN_CENTER, "PREVIEW ONLY",300, 500, 0);

under.endText();

}

stamp.close();

} catch (Throwable de) {

de.printStackTrace();

}

return

 

if anyone knows about how to make watermark transparetn so that the text will be visisble to users.

 

Thanks

Why don't you use the Backgroundband of JasperReport where you can put your text in background of the report content!?!?! (at each Page)

 

So you needn't change the PDF afterwards.

Well we don't have the UltimateGuide but I learned a lot whith Trial&Error!:P

 

Well here you go:

open your JRXML in iReport.

go to the band-properties dialog

select the BACKGROUND Band (first band)

set a band height (e.g. half page-height, or even whole page-height --> see report properties (paper size) depends where you want to place your watermark)

put your Text/graphic etc at this band

voilá that's it.B)

[/ol]

 

just try!

i tried it but still it overlaps the Text. Here i am attaching the sample picture of it.

 

Here is the code i used it for in the background band.

 

<background>

<band height="731" isSplitAllowed="true">

<rectangle>

<reportElement key="rectangle" positionType="Float" x="0" y="0" width="572" height="731"/>

<graphicElement/>

</rectangle>

<staticText>

<reportElement x="56" y="163" width="452" height="60" mode="Transparent">

<printWhenExpression><![CDATA[new Boolean($F{previewOnly}.equals("PREIVIEW"))]]></printWhenExpression>

</reportElement>

<textElement textAlignment="Center">

<font fontName="Book Antiqua" isBold="false" isItalic="true" size="48"/>

</textElement>

<text><![CDATA[PREVIEW ONLY]]></text>

</staticText>

</band>

</background>
