            Description

            The PDF in question has streams that are encoded using Crypt filters. There are three images on page two (10 0 obj, 5 0 obj, and 6 0 obj (smask of 5 0 obj)) which fail to decode correctly. I have yet to find the source of these issue but it would appear that ChunkInputStream.fillBufferFromInputStream() is failing.

            The rest of the document renders ok minus the absense of a header image on pages 5 and greated. Furhter investigation is need to try and determine the cause of this issue.
