Hey all,

I am using aspose.words for to add the watermark into document, but I need to delete this watermark, I search in all side but I don’t find nothing.

if you know about this, Can you help me please?

thanks in advance.

this is my code java:

public static void main(String[] args) {

// TODO Auto-generated method stub

try {

Document doc = new Document(“C:\Users\German\Documents\memorando-general.docx”);

insertWatermarkText(doc, “CONFIDENTIAL”);

doc.save(“C:\Users\German\Documents\memorando-general-OUT.docx”);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

/**

* Inserts a watermark into a document.

*

* @param doc

* The input document.

* @param watermarkText

* Text of the watermark.

*/

private static void insertWatermarkText(Document doc, String watermarkText) throws Exception {

// Create a watermark shape. This will be a WordArt shape.

// You are free to try other shape types as watermarks.

Shape watermark = new Shape(doc, ShapeType.TEXT_PLAIN_TEXT);

// Set up the text of the watermark.

watermark.getTextPath().setText(watermarkText);

watermark.getTextPath().setFontFamily(“Arial Black”);

watermark.setWidth(500);

watermark.setHeight(100);

// Text will be directed from the bottom-left to the top-right corner.

watermark.setRotation(-40);

// Remove the following two lines if you need a solid black text.

watermark.getFill().setColor(Color.red); // Try LightGray to get more Word-style watermark

watermark.setStrokeColor(Color.GRAY); // Try LightGray to get more Word-style watermark

// Place the watermark in the page center.

watermark.setRelativeHorizontalPosition(RelativeHorizontalPosition.PAGE);

watermark.setRelativeVerticalPosition(RelativeVerticalPosition.PAGE);

watermark.setWrapType(WrapType.NONE);

watermark.setVerticalAlignment(VerticalAlignment.CENTER);

watermark.setHorizontalAlignment(HorizontalAlignment.CENTER);

// Create a new paragraph and append the watermark to this paragraph.

Paragraph watermarkPara = new Paragraph(doc);

watermarkPara.appendChild(watermark);

// Insert the watermark into all headers of each document section.

for (Section sect : doc.getSections()) {

// There could be up to three different headers in each section, since we want

// the watermark to appear on all pages, insert into all headers.

insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_PRIMARY);

insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_FIRST);

insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_EVEN);

}

private static void insertWatermarkIntoHeader(Paragraph watermarkPara, Section sect, int headerType) throws Exception {

HeaderFooter header = sect.getHeadersFooters().getByHeaderFooterType(headerType);

if (header == null) {

// There is no header of the specified type in the current section, create it.

header = new HeaderFooter(sect.getDocument(), headerType);

sect.getHeadersFooters().add(header);

}

// Insert a clone of the watermark into the header.

header.appendChild(watermarkPara.deepClone(true));

}

private static void RemoveWatermark(Document doc)

{

//What do I add here?

}

Hi German,

Thanks for your inquiry. You can use the following workflow to be able to remove watermark Shapes from Document:

Document doc = new Document(“D:\temp\in.docx”);

<pre style=“background-color: rgb(255, 255, 255); font-family: “Courier New”; font-size: 9pt;”>
insertWatermarkText(doc, “CONFIDENTIAL”);
removeWatermarkText(doc);

doc.save(“D:\temp\awjava-17.1.0.docx”);

private static void removeWatermarkText(Document doc) throws Exception {

<pre style=“font-family: “Courier New”; font-size: 9pt;”> for(HeaderFooter hf :(Iterable) doc.getChildNodes(NodeType.HEADER_FOOTER, true)){
for(Shape shape :(Iterable) hf.getChildNodes(NodeType.SHAPE, true)){
if(shape.getName().contains(“WaterMark”))
shape.remove();
}
}
}

private static void insertWatermarkText(Document doc, String watermarkText) throws Exception {
// Create a watermark shape. This will be a WordArt shape.
// You are free to try other shape types as watermarks.
Shape watermark = new Shape(doc, ShapeType.TEXT_PLAIN_TEXT);

// Set name to be able to remove it afterwards
watermark.setName(“WaterMark”);

// Set up the text of the watermark.
watermark.getTextPath().setText(watermarkText);
watermark.getTextPath().setFontFamily(“Arial”);
watermark.setWidth(500);
watermark.setHeight(100);
// Text will be directed from the bottom-left to the top-right corner.
watermark.setRotation(-40);
// Remove the following two lines if you need a solid black text.
watermark.getFill().setColor(Color.GRAY); // Try LightGray to get more Word-style watermark
watermark.setStrokeColor(Color.GRAY); // Try LightGray to get more Word-style watermark

// Place the watermark in the page center.
watermark.setRelativeHorizontalPosition(RelativeHorizontalPosition.PAGE);
watermark.setRelativeVerticalPosition(RelativeVerticalPosition.PAGE);
watermark.setWrapType(WrapType.NONE);
watermark.setVerticalAlignment(VerticalAlignment.CENTER);
watermark.setHorizontalAlignment(HorizontalAlignment.CENTER);

// Create a new paragraph and append the watermark to this paragraph.
Paragraph watermarkPara = new Paragraph(doc);
watermarkPara.appendChild(watermark);

// Insert the watermark into all headers of each document section.
for (Section sect : doc.getSections()) {
// There could be up to three different headers in each section, since we want
// the watermark to appear on all pages, insert into all headers.
insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_PRIMARY);
insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_FIRST);
insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_EVEN);
}
}

private static void insertWatermarkIntoHeader(Paragraph watermarkPara, Section sect, int headerType) throws Exception {
HeaderFooter header = sect.getHeadersFooters().getByHeaderFooterType(headerType);

if (header == null) {
// There is no header of the specified type in the current section, create it.
header = new HeaderFooter(sect.getDocument(), headerType);
sect.getHeadersFooters().add(header);
}

// Insert a clone of the watermark into the header.
header.appendChild(watermarkPara.deepClone(true));
}

Hello, I currently need to manage some editable areas that allow me to restrict the writing of some texts in java. I have been looking for information on this subject but I find nothing. Can you help me with this please?

I am currently using version 17.1.0 of aspose.words

Thanks in advance!

awais.hafeez · June 28, 2017, 3:30am

Hi,

Thanks for your inquiry. I think, you may be able to achieve this by protecting whole document and then allow some areas in document to be editable. Please see following example:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.writeln("Some text is added.");
builder.writeln("Some text is added.");
builder.writeln("Some text is added.");

builder.startEditableRange();
builder.write("Some text is added.");

Comment comment = new Comment(doc, "Awais Hafeez", "AH", new Date());
builder.getCurrentParagraph().appendChild(comment);
comment.getParagraphs().add(new Paragraph(doc));
comment.getFirstParagraph().getRuns().add(new Run(doc, "Comment text."));
builder.endEditableRange();

doc.protect(ProtectionType.READ_ONLY);

doc.save(getMyDir() + "awjava-16.3.0.docx");

Hope, this helps.

Best regards,

Hello everyone,

I'm sorry to disturb you but I need to solve this problem, I need to insert the editable areas in a specific place of the document, for example where it finds all the "{}" tags. The previous example is perfect but I need to add this detail, and tried a lot but I could not.

Thanks in advance!
