Class ImageLoader

java.lang.Object

com.lowagie.text.ImageLoader

public class ImageLoader
extends Object

Loads image files such as PNG, JPEG, GIF, TIFF and BMP.

TODO: The goal of this class is to use Java ImageIO to parse images and metadata, and embed the image in the PDF in the best way (the compressed image format, not the raw pixels).

We don't want to maintain our own image codecs.
