I am facing problem with adding the watermark to the PDF file. My goal is to have not selectable, visible watermark in my pdf file.
I am using TextStamp to add watermark to my pdf file, but it is not visible. Funny thing is that I can select this text, copy it to notepad and there it is. I know that to fix that, I have to use setBacground(false), then I see my watermark, but I can still select it, and copy.
I do not want to have ability to select watermark to the user. Then I use setDraw(true), and true - I can not longer select this watermark but it looks very ugly. Is there any fix for that?. I just want to have a watermark in the background that is not selectable.
I have tried with TextStamp and with WatermarkArtifact and still nothing - to be honest I do not know what is the suggested solution for that, I have tried them both. Here is a snipped of my code :
private byte[] addWatermarkToPdf(byte[] data) {
com.aspose.pdf.Document pdfDocument = null;
ByteArrayOutputStream output = new ByteArrayOutputStream();
try {
pdfDocument = new com.aspose.pdf.Document(new ByteArrayInputStream(data));
TextStamp textStamp = new TextStamp("Watermark text");
textStamp.setBackground(true);
textStamp.setWidth(558.35);
textStamp.setHeight(93.05);
textStamp.setRotateAngle(-315);
textStamp.setOpacity(0.5);
textStamp.getTextState().setFont(new FontRepository().openFont("C:\\myFont.ttf"));
textStamp.getTextState().setFontSize(14.0F);
textStamp.getTextState().setForegroundColor(Color.fromArgb(222, 222, 222));
textStamp.setHorizontalAlignment(HorizontalAlignment.Center);
textStamp.setVerticalAlignment(VerticalAlignment.Center);
for (int Page_counter = 1; Page_counter <= pdfDocument.getPages().size(); Page_counter++) {
pdfDocument.getPages().get_Item(Page_counter).addStamp(textStamp);
}
} catch (Exception e) {
log.error("Error while adding watermark to pdf", e);
return output.toByteArray();
}
pdfDocument.save(output, SaveFormat.Pdf);
return output.toByteArray();
}
I am using Aspose.Total for Java v 17.10
EDIT:
I have also tried those approaches, and all of them do not work as I want:
Approach 2
public byte[] addWaterMarkAnnotation3(byte[] data) {
com.aspose.pdf.Document doc = new com.aspose.pdf.Document(new ByteArrayInputStream(data));
FormattedText formattedText = new FormattedText("Watermark", java.awt.Color.BLUE, FontStyle.Courier, EncodingType.Identity_h, true, 72.0F);
WatermarkArtifact artifact = new WatermarkArtifact();
artifact.setText(formattedText);
artifact.setArtifactHorizontalAlignment(HorizontalAlignment.Center);
artifact.setArtifactVerticalAlignment(VerticalAlignment.Center);
artifact.setRotation(45);
artifact.setOpacity(0.5);
artifact.setBackground(true);
doc.getPages().get_Item(1).getArtifacts().add(artifact);
ByteArrayOutputStream out = new ByteArrayOutputStream();
doc.save(out);
return out.toByteArray();
}
Approach 2
public byte[] addWaterMarkAnnotation4(byte[] data) {
com.aspose.pdf.Document doc = new com.aspose.pdf.Document(new ByteArrayInputStream(data));
TextStamp textStamp = new TextStamp("Watermark");
textStamp.setXIndent(25);
textStamp.setYIndent(400);
textStamp.getTextState().setFont(FontRepository.findFont("Arial"));
textStamp.getTextState().setFontSize(72.0F);
textStamp.getTextState().setFontStyle(FontStyles.Italic);
textStamp.getTextState().setForegroundColor(Color.fromArgb(222, 222, 222));
textStamp.setOpacity(50);
textStamp.setStampId(123456);
textStamp.setBackground(true);
doc.getPages().get_Item(1).addStamp(textStamp);
ByteArrayOutputStream out = new ByteArrayOutputStream();
doc.save(out);
return out.toByteArray();
}
Approach 3
public byte[] addWaterMarkAnnotation5(byte[] data) {
PdfFileStamp fileStamp = new PdfFileStamp();
fileStamp.bindPdf(new ByteArrayInputStream(data));
FormattedText formattedText = new FormattedText("Watermark", java.awt.Color.BLUE, FontStyle.Courier, EncodingType.Identity_h, true, 72.0F);
fileStamp.setStartingNumber(1);
final Stamp stamp = new Stamp();
stamp.setRotation(100f);
stamp.setBackground(true);
stamp.setOpacity(0.5f);
stamp.bindLogo(formattedText);
fileStamp.addStamp(stamp);
ByteArrayOutputStream out = new ByteArrayOutputStream();
fileStamp.save(out);
fileStamp.close();
return out.toByteArray();
}
Approach 4
public byte[] addWaterMarkAnnotation7(byte[] data) {
PdfFileStamp fileStamp = new PdfFileStamp();
com.aspose.pdf.Document doc = new com.aspose.pdf.Document(new ByteArrayInputStream(data));
fileStamp.bindPdf(doc);
FormattedText formattedText = new FormattedText("Watermark", java.awt.Color.BLUE, FontStyle.Courier, EncodingType.Identity_h, true, 72.0F);
final Stamp stamp = new Stamp();
stamp.bindLogo(formattedText);
stamp.setOrigin(200,200);
stamp.setRotation(100f);
stamp.setBackground(true);
stamp.setOpacity(0.5f);
fileStamp.addStamp(stamp);
ByteArrayOutputStream out = new ByteArrayOutputStream();
fileStamp.save(out);
fileStamp.close();
return out.toByteArray();
}
Only working solution that I fount, but I am not able to rotate it and make its size in the way I want to is this:
public byte[] addWaterMarkAnnotation(byte[] data) {
// it works in background!!!!!!
com.aspose.pdf.Document document = new com.aspose.pdf.Document(new ByteArrayInputStream(data));
Page page = document.getPages().get_Item(1);
final Rectangle rect = new Rectangle(558.35, 93.05, 400, 600);
rect.rotate(3);
WatermarkAnnotation wa = new WatermarkAnnotation(page, rect);
page.getAnnotations().add(wa);
TextState ts = new TextState();
ts.setFont(new FontRepository().openFont("W:\\myFont.ttf"));
ts.setFontSize(14.0F);
ts.setForegroundColor(Color.fromArgb(222, 222, 222));
ts.setHorizontalAlignment(HorizontalAlignment.Center);
wa.setOpacity(0.8);
wa.setTextAndState(new String[] {"Watermark"}, ts);
ByteArrayOutputStream out = new ByteArrayOutputStream();
document.save(out);
System.out.println(wa.getCharacteristics().getRotate()); // shows me value 0
return out.toByteArray();
}
Maybe someone can help me or figure out how to make it work in other way.
