Details

Summary

An abstract Writer class for documents.

Remarks

DocWriter is the abstract class of several writers such as PdfWriter and HtmlWriter. A DocWriter can be added as a DocListener to a certain Document by getting an instance (see method GetInstance() in the specific writer-classes). Every Element added to the original Document will be written to the stream of the listening DocWriter.

Inheritance

• IDocListener
• IElementListener
• IDisposable

Constructors

DocWriter [1/2]

protected DocWriter()

DocWriter [2/2]

protected DocWriter(Document document, Stream os)

Arguments

Summary

Constructs a DocWriter.

Methods

Add

public virtual void Open()

Summary

Signals that the Document was opened.

SetPageSize

public virtual bool SetPageSize(Rectangle pageSize)

Arguments

Summary

Sets the pagesize.

Returns

a boolean
