Provides the abstract base class for a main document and a glossary document of a Word document.

Aspose.Words represents a Word document as a tree of nodes. DocumentBase is a root node of the tree that contains all other nodes of the document.

DocumentBase also stores document-wide information such as Styles and Lists that the tree nodes might refer to.

Member Function Documentation

◆ get_BackgroundShape()

System::SharedPtr<Aspose::Words::Drawing::Shape> Aspose::Words::DocumentBase::get_BackgroundShape ( ) const

Gets or sets the background shape of the document. Can be null.

Microsoft Word allows only a shape that has its ShapeType property equal to 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 DisplayBackgroundShape to true.

See also: Aspose::Words::Settings::ViewOptions::get_DisplayBackgroundShape; Aspose::Words::DocumentBase::get_PageColor

Examples

Shows how to set a background shape for every page of a document.

auto doc = MakeObject<Document>();
 
ASSERT_TRUE(doc->get_BackgroundShape() == nullptr);
 
// The only shape type that we can use as a background is a rectangle.
auto shapeRectangle = MakeObject<Shape>(doc, ShapeType::Rectangle);
 
// There are two ways of using this shape as a page background.
// 1 -  A flat color:
shapeRectangle->set_FillColor(System::Drawing::Color::get_LightBlue());
doc->set_BackgroundShape(shapeRectangle);
 
doc->Save(ArtifactsDir + u"DocumentBase.BackgroundShape.FlatColor.docx");
 
// 2 -  An image:
shapeRectangle = MakeObject<Shape>(doc, ShapeType::Rectangle);
shapeRectangle->get_ImageData()->SetImage(ImageDir + u"Transparent background logo.png");
 
// Adjust the image's appearance to make it more suitable as a watermark.
shapeRectangle->get_ImageData()->set_Contrast(0.2);
shapeRectangle->get_ImageData()->set_Brightness(0.7);
 
doc->set_BackgroundShape(shapeRectangle);
 
ASSERT_TRUE(doc->get_BackgroundShape()->get_HasImage());
 
// Microsoft Word does not support shapes with images as backgrounds,
// but we can still see these backgrounds in other save formats such as .pdf.
doc->Save(ArtifactsDir + u"DocumentBase.BackgroundShape.Image.pdf");

◆ get_Document()

System::SharedPtr<Aspose::Words::DocumentBase> Aspose::Words::DocumentBase::get_Document ( ) const

overridevirtual

Gets the document to which this node belongs.

The node always belongs to a document even if it has just been created and not yet added to the tree, or if it has been removed from the tree.

Examples

Shows how to create a node and set its owning document.

auto doc = MakeObject<Document>();
auto para = MakeObject<Paragraph>(doc);
para->AppendChild(MakeObject<Run>(doc, u"Hello world!"));
 
// We have not yet appended this paragraph as a child to any composite node.
ASSERT_TRUE(para->get_ParentNode() == nullptr);
 
// If a node is an appropriate child node type of another composite node,
// we can attach it as a child only if both nodes have the same owner document.
// The owner document is the document we passed to the node's constructor.
// We have not attached this paragraph to the document, so the document does not contain its text.
ASPOSE_ASSERT_EQ(para->get_Document(), doc);
ASSERT_EQ(String::Empty, doc->GetText().Trim());
 
// Since the document owns this paragraph, we can apply one of its styles to the paragraph's contents.
para->get_ParagraphFormat()->set_Style(doc->get_Styles()->idx_get(u"Heading 1"));
 
// Add this node to the document, and then verify its contents.
doc->get_FirstSection()->get_Body()->AppendChild(para);
 
ASPOSE_ASSERT_EQ(doc->get_FirstSection()->get_Body(), para->get_ParentNode());
ASSERT_EQ(u"Hello world!", doc->GetText().Trim());

Reimplemented from Aspose::Words::Node.

◆ get_FontInfos()

System::SharedPtr<Aspose::Words::Fonts::FontInfoCollection> Aspose::Words::DocumentBase::get_FontInfos ( ) const

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.

See also: Aspose::Words::Fonts::FontInfoCollection; Aspose::Words::Fonts::FontInfo

Examples

Shows how to print the details of what fonts are present in a document.

auto doc = MakeObject<Document>(MyDir + u"Embedded font.docx");

ASSERT_FALSE(builder->get_ListFormat()->get_IsListItem());
 
// A list allows us to organize and decorate sets of paragraphs with prefix symbols and indents.
// We can create nested lists by increasing the indent level.
// We can begin and end a list by using a document builder's "ListFormat" property.
// Each paragraph that we add between a list's start and the end will become an item in the list.
// Below are two types of lists that we can create using a document builder.
// 1 -  A numbered list:
// Numbered lists create a logical order for their paragraphs by numbering each item.
builder->get_ListFormat()->set_List(doc->get_Lists()->Add(ListTemplate::NumberDefault));
 
ASSERT_TRUE(builder->get_ListFormat()->get_IsListItem());
 
// By setting the "ListLevelNumber" property, we can increase the list level
// to begin a self-contained sub-list at the current list item.
// The Microsoft Word list template called "NumberDefault" uses numbers to create list levels for the first list level.
// Deeper list levels use letters and lowercase Roman numerals.
for (int i = 0; i < 9; i++)
{
    builder->get_ListFormat()->set_ListLevelNumber(i);
    builder->Writeln(String(u"Level ") + i);
}
 
// 2 -  A bulleted list:
// This list will apply an indent and a bullet symbol ("•") before each paragraph.
// Deeper levels of this list will use different symbols, such as "■" and "○".
builder->get_ListFormat()->set_List(doc->get_Lists()->Add(ListTemplate::BulletDefault));
 
for (int i = 0; i < 9; i++)
{
    builder->get_ListFormat()->set_ListLevelNumber(i);

◆ GetType()

virtual const System::TypeInfo& Aspose::Words::DocumentBase::GetType ( ) const

overridevirtual

Reimplemented from Aspose::Words::CompositeNode.

Reimplemented in Aspose::Words::Document, and Aspose::Words::BuildingBlocks::GlossaryDocument.

◆ ImportNode() [1/2]

System::SharedPtr<Aspose::Words::Node> Aspose::Words::DocumentBase::ImportNode	(	System::SharedPtr< Aspose::Words::Node >	srcNode,
		bool	isImportChildren
	)

Imports a node from another document to the current document.

This method uses the UseDestinationStyles 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() or InsertAfter().

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.

Examples

Shows how to import a node from one document to another.

auto srcDoc = MakeObject<Document>();
auto dstDoc = MakeObject<Document>();
 
srcDoc->get_FirstSection()->get_Body()->get_FirstParagraph()->AppendChild(MakeObject<Run>(srcDoc, u"Source document first paragraph text."));
dstDoc->get_FirstSection()->get_Body()->get_FirstParagraph()->AppendChild(MakeObject<Run>(dstDoc, u"Destination document first paragraph text."));
 
// Every node has a parent document, which is the document that contains the node.
// Inserting a node into a document that the node does not belong to will throw an exception.
ASPOSE_ASSERT_NE(dstDoc, srcDoc->get_FirstSection()->get_Document());
ASSERT_THROW(dstDoc->AppendChild(srcDoc->get_FirstSection()), System::ArgumentException);
 
// Use the ImportNode method to create a copy of a node, which will have the document
// that called the ImportNode method set as its new owner document.
auto importedSection = System::DynamicCast<Section>(dstDoc->ImportNode(srcDoc->get_FirstSection(), true));
 
ASPOSE_ASSERT_EQ(dstDoc, importedSection->get_Document());
 
// We can now insert the node into the document.
dstDoc->AppendChild(importedSection);
 
ASSERT_EQ(u"Destination document first paragraph text.\r\nSource document first paragraph text.\r\n", dstDoc->ToString(SaveFormat::Text));

◆ ImportNode() [2/2]

System::SharedPtr<Aspose::Words::Node> Aspose::Words::DocumentBase::ImportNode	(	System::SharedPtr< Aspose::Words::Node >	srcNode,
		bool	isImportChildren,
		Aspose::Words::ImportFormatMode	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() or InsertAfter().

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	Specifies how to merge style formatting that clashes.

Returns: The cloned, imported node. The node belongs to the destination document, but has no parent.

Examples

Shows how to import node from source document to destination document with specific options.

// Create two documents and add a character style to each document.
// Configure the styles to have the same name, but different text formatting.

dstBuilder->Writeln(u"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

ASSERT_EQ(dstStyle->get_Font()->get_Name(), importedSection->get_Body()->get_FirstParagraph()->get_Runs()->idx_get(0)->get_Font()->get_Name());
ASSERT_EQ(dstStyle->get_Name(), importedSection->get_Body()->get_FirstParagraph()->get_Runs()->idx_get(0)->get_Font()->get_StyleName());
 
// If we use ImportFormatMode.KeepDifferentStyles, the source style is preserved,
// and the naming clash resolves by adding a suffix.
dstDoc->ImportNode(srcDoc->get_FirstSection(), true, ImportFormatMode::KeepDifferentStyles);
