Class ZeroPaddedInputStream

java.lang.Object

java.io.InputStream

org.icepdf.core.io.ZeroPaddedInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class ZeroPaddedInputStream
extends java.io.InputStream

When decoding CCITTFaxDecode images via JAI, we sometimes have to zero pad the input data, otherwise JAI will fail instead of it gracefully assuming zero data itself. As well, with some inline images, we can have some trailing whitespace that should be removed. It's typical to have to remove the whitespace and add the zeros.
