Class ImageReferenceFactory

java.lang.Object

org.icepdf.core.pobjects.graphics.ImageReferenceFactory

public class ImageReferenceFactory
extends java.lang.Object

The ImageReferenceFactory determines which implementation of the Image Reference should be created. The ImageReference type can be specified by the following system properties or alternatively by the enum type.

• org.icepdf.core.imageReference = default
• org.icepdf.core.imageReference = scaled
• org.icepdf.core.imageReference = mipmap
• org.icepdf.core.imageReference = smoothScaled

The default value returns an unaltered image, scaled returns a scaled image instance and there MIP mapped returns/picks a scaled image that best fits the current zoom level for a balance of render speed and quality.

Since:

5.0

Gets an instance of an ImageReference object for the given image data. The ImageReference is specified by the system property org.icepdf.core.imageReference or by the static instance variable scale type.

Parameters:

imageStream - image data

resources - parent resource object.

graphicsState - image graphic state.

Returns:

newly create ImageReference.
