Method Detail

alwaysIgnoreGenericHandler

boolean alwaysIgnoreGenericHandler()

processImageData

java.awt.image.BufferedImage processImageData(org.jpedal.objects.GraphicsState gs,
                                              org.jpedal.objects.raw.PdfObject XObject,
                                              org.jpedal.objects.raw.PdfObject ColorSpace)

imageHasBeenScaled

boolean imageHasBeenScaled()

Indicate that image already scaled so should not be scaled/clipped by JPedal

drawImageOnscreen

boolean drawImageOnscreen(java.awt.image.BufferedImage image,
                          int optionsApplied,
                          java.awt.geom.AffineTransform upside_down,
                          java.lang.String currentImageFile,
                          java.awt.Graphics2D g2,
                          boolean renderDirect,
                          ObjectStore objectStore,
                          boolean isPrinting)

Allow user to paint directly onto g2 for screen display

Parameters:

image - - actual BufferedImage

optionsApplied - - any options already done (ie 90 rotate) - values from org.jpedal.constants.PDFImageProcessing

upside_down - - AffineTransform applied to page

currentImageFile - - name of file stored on disk

g2 - - Graphics2D render object

renderDirect - -if being rendered straight to g2 (ie bufferedImage)

objectStore - - JPedals class to access cached images

isPrinting -

Returns:

true to ignore standard JPedal routines and false to use.
