[fw-general] Zend_Pdf::load($pdf), Exception - Unsupported PDF Version

[Jonathan]

This is the code that is in Zend/Pdf/Parser.php

if ($pdfVersion < 0.9 || $pdfVersion >= 1.61) {
    /**
    * @todo
    * To support PDF versions 1.5 (Acrobat 6) and PDF version 1.7 (Acrobat 
7)
    * Stream compression filter must be implemented (for compressed object 
streams).
    * Cross reference streams must be implemented
    */
    throw new Zend_Pdf_Exception(sprintf('Unsupported PDF version. Zend_Pdf 
supports PDF 1.0-1.4. Current version - \'%f\'', $pdfVersion));
}


I have a form that is version 1.7, created with Acrobat 8.  Can anyone 
explain how to implement the "Stream Compression Filter" that the doc says 
to above?



Thank you kindly for any assistance.
