public class GlossaryDocument 
extends DocumentBase

Represents the root element for a glossary document within a Word document. A glossary document is a storage for AutoText, AutoCorrect entries and Building Blocks.

Some documents, usually templates, can contain AutoText, AutoCorrect entries and/or Building Blocks (also known as glossary document entries, document parts or building blocks).

To access building blocks, you need to load a document into a Document object. Building blocks will be available via the Document.GlossaryDocument property.

GlossaryDocument can contain any number of BuildingBlock objects. Each BuildingBlock represents one document part.

Corresponds to the glossaryDocument and docParts elements in OOXML.

Example:

Property Getters/Setters Detail

getBackgroundShape/setBackgroundShape

→ inherited from DocumentBase
public Shape getBackgroundShape() / public void setBackgroundShape(Shape value)
Gets or sets the background shape of the document. Can be null.

Microsoft Word allows only a shape that has its ShapeBase.ShapeType property equal to ShapeType.RECTANGLE to be used as a background shape for a document.

Microsoft Word supports only the fill properties of a background shape. All other properties are ignored.

Setting this property to a non-null value will also set the ViewOptions.DisplayBackgroundShape to true.

Example:

Shows how to set the background shape of a document.
Document doc = new Document();
Assert.assertNull(doc.getBackgroundShape());

// A background shape can only be a rectangle
// We will set the color of this rectangle to light blue
Shape shapeRectangle = new Shape(doc, ShapeType.RECTANGLE);
doc.setBackgroundShape(shapeRectangle);

// This rectangle covers the entire page in the output document
// We can also do this by setting doc.PageColor
shapeRectangle.setFillColor(Color.blue);
doc.save(getArtifactsDir() + "DocumentBase.BackgroundShapeFlatColor.docx");

// Setting the image will override the flat background color with the image
shapeRectangle.getImageData().setImage(getImageDir() + "Transparent background logo.png");
Assert.assertTrue(doc.getBackgroundShape().hasImage());

// This image is a photo with a white background
// To make it suitable as a watermark, we will need to do some image processing
// The default values for these variables are 0.5, so here we are lowering the contrast and increasing the brightness
shapeRectangle.getImageData().setContrast(0.2);
shapeRectangle.getImageData().setBrightness(0.7);

// Microsoft Word does not support images in background shapes, so even though we set the background as an image,
// the output will show a light blue background like before
// However, we can see our watermark in an output pdf
doc.save(getArtifactsDir() + "DocumentBase.BackgroundShape.pdf");

getChildNodes

→ inherited from CompositeNode
public NodeCollection getChildNodes()
Gets all immediate child nodes of this node.

Note, ChildNodes is equivalent to calling GetChildNodes(NodeType.Any, false) and creates and returns a new collection every time it is accessed.

If there are no child nodes, this property returns an empty collection.

Example:

Shows how to enumerate immediate children of a CompositeNode using the enumerator provided by the ChildNodes collection.
Document doc = new Document();

Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);
paragraph.appendChild(new Run(doc, "Hello world!"));
paragraph.appendChild(new Run(doc, " Hello again!"));

NodeCollection children = paragraph.getChildNodes();

// Paragraph may contain children of various types such as runs, shapes and so on
for (Node child : (Iterable<Node>) children)
    if (((child.getNodeType()) == (NodeType.RUN))) {
        Run run = (Run) child;
        System.out.println(run.getText());
    }

getCount

→ inherited from CompositeNode
public int getCount()
Gets the number of immediate children of this node.

Example:

Shows how to add, update and delete child nodes from a CompositeNode's child collection.
Document doc = new Document();

// An empty document has one paragraph by default
Assert.assertEquals(1, doc.getFirstSection().getBody().getParagraphs().getCount());

// A paragraph is a composite node because it can contain runs, which are another type of node
Paragraph paragraph = doc.getFirstSection().getBody().getFirstParagraph();
Run paragraphText = new Run(doc, "Initial text. ");
paragraph.appendChild(paragraphText);

// We will place these 3 children into the main text of our paragraph
Run run1 = new Run(doc, "Run 1. ");
Run run2 = new Run(doc, "Run 2. ");
Run run3 = new Run(doc, "Run 3. ");

// We initialized them but not in our paragraph yet
Assert.assertEquals("Initial text.", paragraph.getText().trim());

// Insert run2 before initial paragraph text. This will be at the start of the paragraph
paragraph.insertBefore(run2, paragraphText);

// Insert run3 after initial paragraph text. This will be at the end of the paragraph
paragraph.insertAfter(run3, paragraphText);

// Insert run1 before every other child node. run2 was the start of the paragraph, now it will be run1
paragraph.prependChild(run1);

Assert.assertEquals("Run 1. Run 2. Initial text. Run 3.", paragraph.getText().trim());
Assert.assertEquals(4, paragraph.getChildNodes(NodeType.ANY, true).getCount());

// Access the child node collection and update/delete children
((Run) paragraph.getChildNodes(NodeType.RUN, true).get(1)).setText("Updated run 2. ");
paragraph.getChildNodes(NodeType.RUN, true).remove(paragraphText);

Assert.assertEquals("Run 1. Updated run 2. Run 3.", paragraph.getText().trim());

getFirstChild

→ inherited from CompositeNode
public Node getFirstChild()
Gets the first child of the node. If there is no first child node, a null is returned.

Example:

Shows how to enumerate immediate child nodes of a composite node using NextSibling.
Document doc = new Document(getMyDir() + "Paragraphs.docx");

// Loop starting from the first child until we reach null

        }
    }
}

getFontInfos

→ inherited from DocumentBase
public FontInfoCollection getFontInfos()
Provides access to properties of fonts used in this document.

This collection of font definitions is loaded as is from the document. Font definitions might be optional, missing or incomplete in some documents.

Do not rely on this collection to ascertain that a particular font is used in the document. You should only use this collection to get information about fonts that might be used in the document.

Example:

Shows how to save a document with embedded TrueType fonts.
Document doc = new Document(getMyDir() + "Document.docx");

FontInfoCollection fontInfos = doc.getFontInfos();
fontInfos.setEmbedTrueTypeFonts(true);
fontInfos.setEmbedSystemFonts(false);
fontInfos.setSaveSubsetFonts(false);

doc.save(getArtifactsDir() + "Font.FontInfoCollection.docx");

Example:

Shows how to print the details of what fonts are present in a document.
Document doc = new Document(getMyDir() + "Embedded font.docx");

FontInfoCollection fonts = doc.getFontInfos();

int fontIndex = 0;
// The fonts info extracted from this document does not necessarily mean that the fonts themselves are
// used in the document. If a font is present but not used then most likely they were referenced at some time
// and then removed from the Document
for (FontInfo info : fonts) {
    // Print out some important details about the font
    System.out.println(MessageFormat.format("Font #{0}", fontIndex));
    System.out.println(MessageFormat.format("Name: {0}", info.getName()));
    System.out.println(MessageFormat.format("IsTrueType: {0}", info.isTrueType()));
    fontIndex++;
}

hasChildNodes

→ inherited from CompositeNode
public boolean hasChildNodes()
Returns true if this node has any child nodes.

Example:

Shows how to combine the rows from two tables into one.
// Load the document
Document doc = new Document(getMyDir() + "Tables.docx");

// Get the first and second table in the document

// The fact that a node always belongs to a document allows us to access and modify 
// properties that reference the document-wide data such as styles or lists
para.getParagraphFormat().setStyleName("Heading 1");

// Now add the paragraph to the main text of the first section

getWarningCallback/setWarningCallback

→ inherited from DocumentBase
public IWarningCallback getWarningCallback() / public void setWarningCallback(IWarningCallback value)
Called during various document processing procedures when an issue is detected that might result in data or formatting fidelity loss. Document may generate warnings at any stage of its existence, so it's important to setup warning callback as early as possible to avoid the warnings loss. E.g. such properties as Document.PageCount actually build the document layout which is used later for rendering, and the layout warnings may be lost if warning callback is specified just for the rendering calls later.

Example:

Demonstrates how to receive notifications of font substitutions by using IWarningCallback.
// Load the document to render
Document doc = new Document(getMyDir() + "Document.docx");

// Create a new class implementing IWarningCallback and assign it to the PdfSaveOptions class
ExRendering.HandleDocumentWarnings callback = new ExRendering.HandleDocumentWarnings();
doc.setWarningCallback(callback);

// We can choose the default font to use in the case of any missing fonts
FontSettings.getDefaultInstance().getSubstitutionSettings().getDefaultFontSubstitution().setDefaultFontName("Arial");

// For testing we will set Aspose.Words to look for fonts only in a folder which doesn't exist. Since Aspose.Words won't
// find any fonts in the specified directory, then during rendering the fonts in the document will be substituted with the default 
// font specified under FontSettings.DefaultFontName. We can pick up on this substitution using our callback
FontSettings.getDefaultInstance().setFontsFolder("", false);

// Pass the save options along with the save path to the save method
doc.save(getArtifactsDir() + "Font.SubstitutionNotification.pdf");

Example:

Shows how to set the property for finding the closest match font among the available font sources instead missing font.
@Test

Method Detail

accept

public boolean accept(DocumentVisitor visitor)
              throws java.lang.Exception
Accepts a visitor.

Enumerates over this node and all of its children. Each node calls a corresponding method on DocumentVisitor.

For more info see the Visitor design pattern.

Calls DocumentVisitor.visitGlossaryDocumentStart(com.aspose.words.GlossaryDocument), then calls accept(com.aspose.words.DocumentVisitor) for all child nodes of this node and then calls DocumentVisitor.visitGlossaryDocumentEnd(com.aspose.words.GlossaryDocument) at the end.

Note: A glossary document node and its children are not visited when you execute a Visitor over a Document. If you want to execute a Visitor over a glossary document, you need to call accept(com.aspose.words.DocumentVisitor).

Parameters:
visitor - The visitor that will visit the nodes.
Returns:
True if all nodes were visited; false if DocumentVisitor stopped the operation before visiting all nodes.

appendChild

→ inherited from CompositeNode
public Node appendChild(Node newChild)
Adds the specified node to the end of the list of child nodes for this node.

If the newChild is already in the tree, it is first removed.

If the node being inserted was created from another document, you should use importNode(com.aspose.words.Node,boolean,int) to import the node to the current document. The imported node can then be inserted into the current document.

Parameters:
newChild - The node to add.
Returns:
The node added.

Example:

Shows how to construct an Aspose Words document node by node.
Document doc = new Document();

// A newly created blank document still comes one section, one body and one paragraph
// Calling this method will remove all those nodes to completely empty the document
doc.removeAllChildren();

// This document now has no composite nodes that content can be added to
// If we wish to edit it, we will need to repopulate its node collection,
// which we will start to do with by creating a new Section node
Section section = new Section(doc);

// Append the section to the document
doc.appendChild(section);

// Lets set some properties for the section
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.LETTER);

// The section that we created is empty, lets populate it. The section needs at least the Body node
Body body = new Body(doc);
section.appendChild(body);

// The body needs to have at least one paragraph
// Note that the paragraph has not yet been added to the document, 
// but we have to specify the parent document
// The parent document is needed so the paragraph can correctly work
// with styles and other document-wide information
Paragraph para = new Paragraph(doc);
body.appendChild(para);

// We can set some formatting for the paragraph
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);

// So far we have one empty paragraph in the document
// The document is valid and can be saved, but lets add some text before saving
// Create a new run of text and add it to our paragraph
Run run = new Run(doc);
run.setText("Hello World!");

getBuildingBlock

public BuildingBlock getBuildingBlock(int gallery, java.lang.String category, java.lang.String name)
Finds a building block using the specified gallery, category and name.

This is a convenience method that iterates over all building blocks in this collection and returns the first building block that matches the specified gallery, category and name.

Microsoft Word organizes building blocks into galleries. The galleries are predefined using the BuildingBlockGallery enum. Within each gallery, building blocks can be organized into one or more categories. The category name is a string. Each building block has a name. A building block name is not guaranteed to be unique.

Parameters:
gallery - A BuildingBlockGallery value. The gallery criteria.
category - The category criteria. Can be null, in which case it will not be used for comparison.
name - The building block name criteria.
Returns:
The matching building block or null if a match was not found.

Example:

getChild

→ inherited from CompositeNode
public Node getChild(int nodeType, int index, boolean isDeep)
Returns an Nth child node that matches the specified type.

If index is out of range, a null is returned.

Note that markup nodes (NodeType.STRUCTURED_DOCUMENT_TAG and NodeType.SMART_TAG) are traversed even when isDeep = false and GetChild is invoked for non-markup node type. For example if the first run in a para is wrapped in a StructuredDocumentTag, it will still be returned by GetChild(NodeType.Run, 0, false).
Parameters:
nodeType - A NodeType value. Specifies the type of the child node.
index - Zero based index of the child node to select. Negative indexes are also allowed and indicate access from the end, that is -1 means the last node.
isDeep - True to select from all child nodes recursively. False to select only among immediate children. See remarks for more info.
Returns:
The child node that matches the criteria or null if no matching node is found.

Example:

Shows how to expand the formatting from styles onto the rows and cells of the table as direct formatting.
Document doc = new Document(getMyDir() + "Tables.docx");
Table table = (Table) doc.getChild(NodeType.TABLE, 0, true);

// First print the color of the cell shading. This should be empty as the current shading
// is stored in the table style
double cellShadingBefore = table.getFirstRow().getRowFormat().getHeight();
System.out.println("Cell shading before style expansion: " + cellShadingBefore);

// Expand table style formatting to direct formatting
doc.expandTableStylesToDirectFormatting();

// Now print the cell shading after expanding table styles. A blue background pattern color
// should have been applied from the table style
double cellShadingAfter = table.getFirstRow().getRowFormat().getHeight();
System.out.println("Cell shading after style expansion: " + cellShadingAfter);

doc.save(getArtifactsDir() + "Document.TableStyleToDirectFormatting.docx");

Example:

Shows how to enumerate immediate children of a CompositeNode using the enumerator provided by the ChildNodes collection.
Document doc = new Document();

Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);
paragraph.appendChild(new Run(doc, "Hello world!"));
paragraph.appendChild(new Run(doc, " Hello again!"));

NodeCollection children = paragraph.getChildNodes();

// Paragraph may contain children of various types such as runs, shapes and so on
for (Node child : (Iterable<Node>) children)
    if (((child.getNodeType()) == (NodeType.RUN))) {
        Run run = (Run) child;
        System.out.println(run.getText());
    }

getChildNodes

→ inherited from CompositeNode
public NodeCollection getChildNodes(int nodeType, boolean isDeep)
Returns a live collection of child nodes that match the specified type.

The collection of nodes returned by this method is always live.

A live collection is always in sync with the document. For example, if you selected all sections in a document and enumerate through the collection deleting the sections, the section is removed from the collection immediately when it is removed from the document.

Parameters:
nodeType - A NodeType value. Specifies the type of nodes to select.
isDeep - True to select from all child nodes recursively. False to select only among immediate children.
Returns:
A live collection of child nodes of the specified type.

Example:

Shows how to get all comments with all replies.
Document doc = new Document(getMyDir() + "Comments.docx");

// Get all comment from the document
NodeCollection comments = doc.getChildNodes(NodeType.COMMENT, true);

// For all comments and replies we identify comment level and info about it
for (Comment comment : (Iterable<Comment>) comments) {
    if (comment.getAncestor() == null) {
        System.out.println("\nThis is a top-level comment");
        System.out.println("Comment author: " + comment.getAuthor());
        System.out.println("Comment text: " + comment.getText());

        for (Comment commentReply : comment.getReplies()) {

            System.out.println("\tReply author: " + commentReply.getAuthor());
            System.out.println("\tReply text: " + commentReply.getText());
        }
    }
}

Example:

Shows how to extract images from a document and save them as files.
Document doc = new Document(getMyDir() + "Images.docx");

NodeCollection shapes = doc.getChildNodes(NodeType.SHAPE, true);

int imageIndex = 0;
for (Shape shape : (Iterable<Shape>) shapes) {

        shape.getImageData().save(getArtifactsDir() + imageFileName);
        imageIndex++;
    }
}

Assert.assertEquals(9, imageIndex);

getText

→ inherited from CompositeNode
public java.lang.String getText()
Gets the text of this node and of all its children.

The returned string includes all control and special characters as described in ControlChar.

Example:

Shows how to output all paragraphs in a document that are bulleted or numbered.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.getListFormat().applyNumberDefault();
builder.writeln("Numbered list item 1");
builder.writeln("Numbered list item 2");
builder.writeln("Numbered list item 3");
builder.getListFormat().removeNumbers();

builder.getListFormat().applyBulletDefault();
builder.writeln("Bulleted list item 1");
builder.writeln("Bulleted list item 2");
builder.writeln("Bulleted list item 3");
builder.getListFormat().removeNumbers();

NodeCollection paras = doc.getChildNodes(NodeType.PARAGRAPH, true);
for (Paragraph para : (Iterable<Paragraph>) paras) {
    if (para.getListFormat().isListItem()) {
        System.out.println(java.text.MessageFormat.format("*** A paragraph belongs to list {0}", para.getListFormat().getList().getListId()));
        System.out.println(para.getText());
    }
}

Example:

Shows the difference between calling the GetText and ToString methods on a node.
Document doc = new Document();

// Enter a field into the document
DocumentBuilder builder = new DocumentBuilder(doc);
builder.insertField("MERGEFIELD Field");

// GetText will retrieve all field codes and special characters
Assert.assertEquals("\u0013MERGEFIELD Field\u0014«Field»\u0015\f", doc.getText());

// ToString will give us the plaintext version of the document in the save format we put into the parameter
Assert.assertEquals("«Field»\r\n", doc.toString(SaveFormat.TEXT));

importNode

→ inherited from DocumentBase
public Node importNode(Node srcNode, boolean isImportChildren)

Imports a node from another document to the current document.

This method uses the ImportFormatMode.USE_DESTINATION_STYLES option to resolve formatting.

Importing a node creates a copy of the source node belonging to the importing document. The returned node has no parent. The source node is not altered or removed from the original document.

Before a node from another document can be inserted into this document, it must be imported. During import, document-specific properties such as references to styles and lists are translated from the original to the importing document. After the node was imported, it can be inserted into the appropriate place in the document using insertBefore(com.aspose.words.Node,com.aspose.words.Node) or insertAfter(com.aspose.words.Node,com.aspose.words.Node).

If the source node already belongs to the destination document, then simply a deep clone of the source node is created.

Parameters:
srcNode - The node being imported.
isImportChildren - True to import all child nodes recursively; otherwise, false.
Returns:
The cloned node that belongs to the current document.
See Also:
NodeImporter

Example:

Shows how to import node from source document to destination document.
Document src = new Document();
Document dst = new Document();

// Add text to both documents
src.getFirstSection().getBody().getFirstParagraph().appendChild(new Run(src, "Source document first paragraph text."));
dst.getFirstSection().getBody().getFirstParagraph().appendChild(new Run(dst, "Destination document first paragraph text."));

// In order for a child node to be successfully appended to another node in a document,
// both nodes must have the same parent document, or an exception is thrown
Assert.assertNotEquals(dst, src.getFirstSection().getDocument());
Assert.assertThrows(IllegalArgumentException.class, () -> dst.appendChild(src.getFirstSection()));

// For that reason, we can't just append a section of the source document to the destination document using Node.AppendChild()
// Document.ImportNode() lets us get around this by creating a clone of a node and sets its parent to the calling document
Section importedSection = (Section) dst.importNode(src.getFirstSection(), true);

// Now it is ready to be placed in the document
dst.appendChild(importedSection);

// Our document now contains both the original and imported section
Assert.assertEquals("Destination document first paragraph text.\r\nSource document first paragraph text.\r\n",
        dst.toString(SaveFormat.TEXT));

importNode

→ inherited from DocumentBase
public Node importNode(Node srcNode, boolean isImportChildren, int importFormatMode)

Imports a node from another document to the current document with an option to control formatting.

This overload is useful to control how styles and list formatting are imported.

Importing a node creates a copy of the source node belonging to the importing document. The returned node has no parent. The source node is not altered or removed from the original document.

Before a node from another document can be inserted into this document, it must be imported. During import, document-specific properties such as references to styles and lists are translated from the original to the importing document. After the node was imported, it can be inserted into the appropriate place in the document using insertBefore(com.aspose.words.Node,com.aspose.words.Node) or insertAfter(com.aspose.words.Node,com.aspose.words.Node).

If the source node already belongs to the destination document, then simply a deep clone of the source node is created.

Parameters:
srcNode - The node to imported.
isImportChildren - True to import all child nodes recursively; otherwise, false.
importFormatMode - A ImportFormatMode value. Specifies how to merge style formatting that clashes.
Returns:
The cloned, imported node. The node belongs to the destination document, but has no parent.
See Also:
ImportFormatMode, NodeImporter

Example:

Shows how to import node from source document to destination document with specific options.
// Create two documents with two styles that differ in font but have the same name
Document src = new Document();
Style srcStyle = src.getStyles().add(StyleType.CHARACTER, "My style");
srcStyle.getFont().setName("Courier New");
DocumentBuilder srcBuilder = new DocumentBuilder(src);
srcBuilder.getFont().setStyle(srcStyle);
srcBuilder.writeln("Source document text.");

Document dst = new Document();
Style dstStyle = dst.getStyles().add(StyleType.CHARACTER, "My style");
dstStyle.getFont().setName("Calibri");
DocumentBuilder dstBuilder = new DocumentBuilder(dst);
dstBuilder.getFont().setStyle(dstStyle);
dstBuilder.writeln("Destination document text.");

// Import the Section from the destination document into the source document, causing a style name collision
// If we use destination styles then the imported source text with the same style name as destination text
// will adopt the destination style 
Section importedSection = (Section) dst.importNode(src.getFirstSection(), true, ImportFormatMode.USE_DESTINATION_STYLES);
Assert.assertEquals(dstStyle.getFont().getName(), importedSection.getBody().getFirstParagraph().getRuns().get(0).getFont().getName());
Assert.assertEquals(dstStyle.getName(), importedSection.getBody().getFirstParagraph().getRuns().get(0).getFont().getStyleName());

// If we use ImportFormatMode.KeepDifferentStyles,
// the source style is preserved and the naming clash is resolved by adding a suffix 
dst.importNode(src.getFirstSection(), true, ImportFormatMode.KEEP_DIFFERENT_STYLES);
Assert.assertEquals(dstStyle.getFont().getName(), dst.getStyles().get("My style").getFont().getName());
Assert.assertEquals(srcStyle.getFont().getName(), dst.getStyles().get("My style_0").getFont().getName());

indexOf

→ inherited from CompositeNode
public int indexOf(Node child)
Returns the index of the specified child node in the child node array. Returns -1 if the node is not found in the child nodes.

Example:

Shows how to get the index of a given child node from its parent.
Document doc = new Document(getMyDir() + "Rendering.docx");

// Get the body of the first section in the document
Body body = doc.getFirstSection().getBody();

// Retrieve the index of the last paragraph in the body
Assert.assertEquals(24, body.getChildNodes().indexOf(body.getLastParagraph()));

insertAfter

→ inherited from CompositeNode
public Node insertAfter(Node newChild, Node refChild)
Inserts the specified node immediately after the specified reference node.

If refChild is null, inserts newChild at the beginning of the list of child nodes.

If the newChild is already in the tree, it is first removed.

If the node being inserted was created from another document, you should use importNode(com.aspose.words.Node,boolean,int) to import the node to the current document. The imported node can then be inserted into the current document.

Parameters:
newChild - The Node to insert.
refChild - The Node that is the reference node. The newNode is placed after the refNode.
Returns:
The inserted node.

Example:

Shows how to replace all textboxes with images.
Document doc = new Document(getMyDir() + "Textboxes in drawing canvas.docx");

// This gets a live collection of all shape nodes in the document
NodeCollection shapeCollection = doc.getChildNodes(NodeType.SHAPE, true);

// Since we will be adding/removing nodes, it is better to copy all collection
// into a fixed size array, otherwise iterator will be invalidated
Node[] shapes = shapeCollection.toArray();

for (Node node : shapes) {
    Shape shape = (Shape) node;
    // Filter out all shapes that we don't need
    if (shape.getShapeType() == ShapeType.TEXT_BOX) {
        // Create a new shape that will replace the existing shape
        Shape image = new Shape(doc, ShapeType.IMAGE);

        // Load the image into the new shape
        image.getImageData().setImage(getImageDir() + "Windows MetaFile.wmf");

        // Make new shape's position to match the old shape
        image.setLeft(shape.getLeft());
        image.setTop(shape.getTop());
        image.setWidth(shape.getWidth());
        image.setHeight(shape.getHeight());
        image.setRelativeHorizontalPosition(shape.getRelativeHorizontalPosition());
        image.setRelativeVerticalPosition(shape.getRelativeVerticalPosition());
        image.setHorizontalAlignment(shape.getHorizontalAlignment());
        image.setVerticalAlignment(shape.getVerticalAlignment());
        image.setWrapType(shape.getWrapType());
        image.setWrapSide(shape.getWrapSide());

        // Insert new shape after the old shape and remove the old shape
        shape.getParentNode().insertAfter(image, shape);
        shape.remove();
    }
}

doc.save(getArtifactsDir() + "Shape.ReplaceTextboxesWithImages.docx");

Example:

Shows the difference between calling the GetText and ToString methods on a node.
Document doc = new Document();

// Enter a field into the document
DocumentBuilder builder = new DocumentBuilder(doc);
builder.insertField("MERGEFIELD Field");

// GetText will retrieve all field codes and special characters
Assert.assertEquals("\u0013MERGEFIELD Field\u0014«Field»\u0015\f", doc.getText());

// ToString will give us the plaintext version of the document in the save format we put into the parameter
Assert.assertEquals("«Field»\r\n", doc.toString(SaveFormat.TEXT));
