Constructor Detail

PdfCanvasCsConverter

public PdfCanvasCsConverter(com.itextpdf.kernel.pdf.PdfDocument document,
                            AbstractCsConverter csConverter,
                            OptimizationSession session)

Instantiates a new PdfCanvasCsConverter instance based on PDF document and color space converter.

Parameters:

document - the document that the resulting content stream will be written to

csConverter - the color space converter instance

session - is an auxiliary object used to support share data between stages of optimization process

Method Detail

getCanvas

public com.itextpdf.kernel.pdf.canvas.PdfCanvas getCanvas()

Gets resulting PDF canvas.

Returns:

the PDF canvas instance

invokeOperator

protected void invokeOperator(com.itextpdf.kernel.pdf.PdfLiteral operator,
                              List operands)

Process PDF content stream operators. If it is operator which define or use color space, his operands will be converted by calling the AbstractCsConverter.convertContentStreamOperands(PdfColorSpace, PdfColorSpace, String, List, OptimizationSession) method and then written to the resulting PDF canvas, otherwise operator with operands will be immediately written to th resulting PDF canvas.

Overrides:

invokeOperator in class com.itextpdf.kernel.pdf.canvas.parser.PdfCanvasProcessor

Parameters:

operator -

operands -
