Watermarks in Word documents are usually represented by shapes. Using GroupDocs.Watermark API you can easily remove shape of any type from any level of document structure.
Removing watermark from a particular section of a Word document using GroupDocs.Watermark consists of following steps.
- Load the document
- Create and initialize image or text search criteria
- Find possible watermarks
- Remove found watermarks
- Save the document
Following code sample shows how to remove watermark from a particular section.
advanced_usage.add_watermarks_to_word_processing.WordProcessingRemoveWatermarkFromSection
WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\document.docx"
Watermarker watermarker = new Watermarker("document.docx", loadOptions);
// Initialize search criteria
ImageSearchCriteria imageSearchCriteria = new ImageDctHashSearchCriteria("logo.png");
TextSearchCriteria textSearchCriteria = new TextSearchCriteria("Company Name");
// Call Search method for the section
WordProcessingContent content = watermarker.getContent(WordProcessingContent.class);
PossibleWatermarkCollection possibleWatermarks = content.getSections().get_Item(0).search(textSearchCriteria.or(imageSearchCriteria));
// Remove all found watermarks
for (int i = possibleWatermarks.getCount() - 1; i >= 0; i--)
{
possibleWatermarks.removeAt(i);
}
watermarker.save("document.docx");
watermarker.close();
You can also call search() method for a particular header or footer as shown in the below code sample.
advanced_usage.add_watermarks_to_word_processing.WordProcessingFindWatermarkInHeaderFooter
WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\document.docx"
Watermarker watermarker = new Watermarker("document.docx", loadOptions);
// Initialize search criteria
ImageSearchCriteria imageSearchCriteria = new ImageDctHashSearchCriteria("logo.png");
TextSearchCriteria textSearchCriteria = new TextSearchCriteria("Company Name");
WordProcessingContent content = watermarker.getContent(WordProcessingContent.class);
PossibleWatermarkCollection possibleWatermarks = content
.getSections().get_Item(0)
.getHeadersFooters().getByOfficeHeaderFooterType(OfficeHeaderFooterType.HeaderPrimary)
.search(textSearchCriteria.or(imageSearchCriteria));
// Remove all found watermarks
for (int i = possibleWatermarks.getCount() - 1; i >= 0; i--)
{
possibleWatermarks.removeAt(i);
}
watermarker.save("document.docx");
watermarker.close();
search() method returns a collection of PossibleWatermark instances for all document types. But in some cases, it’s necessary to get more information about Word shapes than common API offers. GroupDocs.Watermark enables you to extract the information about all the shapes as shown in the below code sample.
advanced_usage.add_watermarks_to_word_processing.WordProcessingGetShapesInformation
WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\document.docx"
Watermarker watermarker = new Watermarker("document.docx", loadOptions);
WordProcessingContent content = watermarker.getContent(WordProcessingContent.class);
for (WordProcessingSection section : content.getSections())
{
for (WordProcessingShape shape : section.getShapes())
{
if (shape.getHeaderFooter() != null)
{
System.out.println("In header/footer");
}
System.out.println(shape.getShapeType());
System.out.println(shape.getWidth());
System.out.println(shape.getHeight());
System.out.println(shape.isWordArt());
System.out.println(shape.getRotateAngle());
System.out.println(shape.getAlternativeText());
System.out.println(shape.getName());
System.out.println(shape.getX());
System.out.println(shape.getY());
System.out.println(shape.getText());
if (shape.getImage() != null)
{
System.out.println(shape.getImage().getWidth());
System.out.println(shape.getImage().getHeight());
System.out.println(shape.getImage().getBytes().length);
}
System.out.println(shape.getHorizontalAlignment());
System.out.println(shape.getVerticalAlignment());
System.out.println(shape.getRelativeHorizontalPosition());
System.out.println(shape.getRelativeVerticalPosition());
}
}
watermarker.close();
You can extract information about the existing shapes of particular types. The WordProcessingShapeType enum is available to check the types possibly available shapes.
The following code snippet demonstrates the usage of WordProcessingShapeType enum.
advanced_usage.add_watermarks_to_word_processing.WordProcessingShapeTypeUsage
WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\document.docx"
Watermarker watermarker = new Watermarker("document.docx", loadOptions);
WordProcessingContent content = watermarker.getContent(WordProcessingContent.class);
for (WordProcessingSection section : content.getSections())
{
for (WordProcessingShape shape : section.getShapes())
{
//Check for Diagonal Corners Rounded shapes
if (shape.getShapeType() == WordProcessingShapeType.DiagonalCornersRounded)
{
System.out.println("Diagonal Corners Rounded shape found");
//Write text on all Diagonal Corners Rounded shapes
shape.getFormattedTextFragments().add("I am Diagonal Corner Rounded", new Font("Calibri", 8, FontStyle.Bold), Color.getRed(), Color.getAqua());
}
}
}
watermarker.save("document.docx");
watermarker.close();
You can also remove a particular shape from a Word document as shown in the below code sample.
advanced_usage.add_watermarks_to_word_processing.WordProcessingRemoveShape
WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\document.docx"
Watermarker watermarker = new Watermarker("document.docx", loadOptions);
WordProcessingContent content = watermarker.getContent(WordProcessingContent.class);
// Remove shape by index
content.getSections().get_Item(0).getShapes().removeAt(0);
// Remove shape by reference
content.getSections().get_Item(0).getShapes().remove(content.getSections().get_Item(0).getShapes().get_Item(0));
watermarker.save("document.docx");
watermarker.close();
You can also find and remove the shapes with a particular text formatting from a Word document as shown in the below code sample.
advanced_usage.add_watermarks_to_word_processing.WordProcessingRemoveShapesWithParticularTextFormatting
WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\document.docx"
Watermarker watermarker = new Watermarker("document.docx", loadOptions);
WordProcessingContent content = watermarker.getContent(WordProcessingContent.class);
for (WordProcessingSection section : content.getSections())
{
for (int i = section.getShapes().getCount() - 1; i >= 0; i--)
{
for (FormattedTextFragment fragment : section.getShapes().get_Item(i).getFormattedTextFragments())
{
if (fragment.getForegroundColor().equals(Color.getRed()) && fragment.getFont().getFamilyName() == "Arial")
{
section.getShapes().removeAt(i);
break;
}
}
}
}
watermarker.save("document.docx");
watermarker.close();
Using GroupDocs.Watermark for Java, you can also remove or replace hyperlink associated with a particular shape inside a Word document. Use following code sample to achieve this functionality.

WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\document.docx"
Watermarker watermarker = new Watermarker("document.docx", loadOptions);
WordProcessingContent content = watermarker.getContent(WordProcessingContent.class);
// Replace hyperlink
content.getSections().get_Item(0).getShapes().get_Item(0).setHyperlink("https://www.groupdocs.com/");
// Remove hyperlink
content.getSections().get_Item(0).getShapes().get_Item(1).setHyperlink(null);
watermarker.save("document.docx");
watermarker.close();
GroupDocs.Watermark supports replacing text for particular shapes in a Word document. Following code sample shows the usage of this feature.

for (WordProcessingShape shape : content.getSections().get_Item(0).getShapes())
{
if (shape.getText().contains("Some text"))
{
shape.getFormattedTextFragments().clear();
shape.getFormattedTextFragments().add("Another text", new Font("Calibri", 19, FontStyle.Bold), Color.getRed(), Color.getAqua());
}
}
// Save document
watermarker.save("document.docx");
watermarker.close();
GroupDocs.Watermark also allows you to replace the image of the particular shapes in a Word document as shown in the following code sample.

File imageFile = new File("test.png");
byte[] imageBytes = new byte[(int) imageFile.length()];
InputStream imageInputStream = new FileInputStream(imageFile);
imageInputStream.read(imageBytes);
imageInputStream.close();
// Set shape image
for (WordProcessingShape shape : content.getSections().get_Item(0).getShapes())
{
if (shape.getImage() != null)
{
shape.setImage(new WordProcessingWatermarkableImage(imageBytes));
}
}
// Save document
watermarker.save("document.docx");
watermarker.close();
GroupDocs.Watermark also provides the feature of modifying properties (setAlternativeText(), setRotateAngle(), setX(), setY(), setHeight(), setWidth() or setBehindText()) of particular shapes in a Word document. Following code sample shows how to use this feature.
