Detailed Description

Dictionary wrapper that represent special type of color space, that uses pattern objects as the equivalent of colour values instead of the numeric component values used with other spaces.

Dictionary wrapper that represent special type of color space, that uses pattern objects as the equivalent of colour values instead of the numeric component values used with other spaces. A pattern object shall be a dictionary or a stream, depending on the type of pattern. For mor information see paragraph 8.7 in ISO-32000-1.

Member Function Documentation

Flush()

override void iText.Kernel.Pdf.Colorspace.PdfPattern.Flush ( )

inlinevirtual

To manually flush a PdfObject behind this wrapper, you have to ensure that this object is added to the document, i.e. it has an indirect reference. Basically this means that before flushing you need to explicitly call iText.Kernel.Pdf.PdfObjectWrapper.MakeIndirect(iText.Kernel.Pdf.PdfDocument)For example: wrapperInstance.makeIndirect(document).flush(); Note that not every wrapper require this, only those that have such warning in documentation.

Reimplemented from iText.Kernel.Pdf.PdfObjectWrapper< PdfDictionary >.

Reimplemented in iText.Kernel.Pdf.Colorspace.PdfPattern.Tiling.

GetMatrix()

virtual PdfArray iText.Kernel.Pdf.Colorspace.PdfPattern.GetMatrix ( )

inlinevirtual

Gets a transformation matrix that maps the pattern’s internal coordinate system to the default coordinate system of the pattern’s parent content stream.

Gets a transformation matrix that maps the pattern’s internal coordinate system to the default coordinate system of the pattern’s parent content stream. 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 shall be interpreted.

Returns

pattern matrix

GetPatternInstance()

static iText.Kernel.Pdf.Colorspace.PdfPattern iText.Kernel.Pdf.Colorspace.PdfPattern.GetPatternInstance ( PdfDictionary  pdfObject )

inlinestatic

Creates the instance wrapper of correct type from the iText.Kernel.Pdf.PdfDictionary

Parameters

pdfObject

the iText.Kernel.Pdf.PdfDictionary that represent Pattern

Returns

new wrapper instance.

SetMatrix()

virtual void iText.Kernel.Pdf.Colorspace.PdfPattern.SetMatrix ( PdfArray  matrix )

inlinevirtual

Sets a transformation matrix that maps the pattern’s internal coordinate system to the default coordinate system of the pattern’s parent content stream.

Sets a transformation matrix that maps the pattern’s internal coordinate system to the default coordinate system of the pattern’s parent content stream. 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 shall be interpreted.

Parameters

matrix

pattern matrix to set
