Be warned, the Adobe documentation is incomplete in some subtle details.
E.g. the Length of an Stream is specified so vaguely, that the stored
Length (observed) frequently is something between the number of data
bytes with or without embedded EOL markers. See the PDF spec, 22.214.171.124
Such flaws can prevent the decoding of a PDF document, because the exact
stream decoder is a secret of Adobe (like details of .NET are Microsoft
Please let me know when somebody finds source code of an PDF parser,
that e.g. allows to extract the exact page count from any PDF document.
