[英]How set watermark in word file using Aspose.Word for Java
這是我的代碼。 但是它不起作用。
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");
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);
}
}
我已經解決了我的問題。 實際上這是jar文件沖突。 在這里,我得到了新的jar文件。 現在我的代碼正在運行。 這是更新的代碼:
/**
* Inserts a watermark into a document.
*
* @param doc The input document file.
* @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");
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);
}
System.out.println("Watermark Set");
}
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));
