Class ImageIOImageProcessor

java.lang.Object

er.attachment.thumbnail.ERImageProcessor

er.attachment.thumbnail.ImageIOImageProcessor

All Implemented Interfaces:

IERImageProcessor

public class ImageIOImageProcessor
extends ERImageProcessor

ImageIOImageProcessor is an implementation of the IImageProcessor interface on top of Mac OS X's ImageIO and CoreImage libraries. This is, by far, the fastest implementation of image processing provided. To use this implementation, you must build the native ImageIOImageProcessor.jnilib provided in the Native/MacOSX/ImageIOImageProcessor xcode project and place the library in your JNI library path (for example, /Library/Java/Extensions).
