java.lang.Object
  org.freehep.graphicsio.pdf.PDFPaintDelayQueue

public class PDFPaintDelayQueue
extends java.lang.Object

Delay Paint objects (gradient/texture, not color) for writing pattern/shading/function dictionaries to the pdf file when the pageStream is complete.
TODO: - reuse pattern dictionaries if possible - cyclic function not working yet (ps calculation)

Constructor Summary

PDFPaintDelayQueue(PDFWriter pdf, PDFImageDelayQueue imageDelayQueue)
Don't forget to call setPageMatrix().

Method Summary

protected void	addCyclicFunction(java.lang.String functionRef, double[] c0, double[] c1, double[] dom) Writes a type 4 (PostScript calculator) function that describes a triangle function to the pdf file.
int	addPatterns() Adds all names to the dictionary which should be the value of the resources dicionrary's /Pattern entry.
PDFName	delayPaint(java.awt.Paint paint, java.awt.geom.AffineTransform transform, java.lang.String writeAs)
void	processAll() Creates a stream for every delayed image.
void	setPageMatrix(java.awt.geom.AffineTransform t) Call this method in order to inform this class about the transformation that is necessary to map the pattern's coordinate space to the default coordinate system of the parent's content stream (in our case the flipping of the page).
