Method Detail

wrap

public static Pattern<?> wrap(PdfDirectObject baseObject)

Wraps the specified base object into a pattern object.

Parameters:

baseObject - Base object of a pattern object.

Returns:

Pattern object corresponding to the base object.

clone

public Object clone(Document context)

Description copied from class: PdfObjectWrapper

Gets a clone of the object, registered inside the given document context.

Overrides:

clone in class PdfObjectWrapper<TDataObject extends PdfDataObject>

Parameters:

context - Which document the clone has to be registered in.

getComponents

public List<PdfDirectObject> getComponents()

Description copied from class: Color

Gets the components defining this color value.

Specified by:

getComponents in class Color<TDataObject extends PdfDataObject>

getMatrix

public double[] getMatrix()

Gets the pattern matrix, a transformation matrix that maps the pattern's internal coordinate system to the default coordinate system of the pattern's parent content stream (the content stream in which the pattern is defined as a resource).

The concatenation of the pattern matrix with that of the parent content stream establishes the pattern coordinate space, within which all graphics objects in the pattern are interpreted.

getDictionary

protected final PdfDictionary getDictionary()

Gets this pattern's dictionary.
