            Description

            The PDF in question has an inline image on page 70 that loads a a black image. The issue is because of a data length issue between the index colour model data and the data length of the actual image stream. As far as I can tell this issue was introduced in PDF-866 when fixing up some stuff with inline image parsing. A side effect of this work is that the data stream can be a little long.

            I've update the code to use the length of the needed data and not the data length of the stream. Image appears correctly.
