Zend framework load PDF error: with message 'cross-reference streams are not supported yet.

I inherited zend_pdf and wrote a static method.

Public static function load ($ source = NULL, $ revision = NULL)

{

Return new dhr_pdf ($ source, $ revision, true );

}

Then an error occurs during access through $ PDF = dhr_pdf: load ($ salespdfpath );

The following error occurred:

Exception 'zend _ end _exception' with message' cross-reference streams are not supported yet. 'In c: \ Users \ n. zhang \ Documents \ tools \ library \ Zend \ PDF \ parser.

The PDF version is detected later.

Now the Zend Framework Version I used is 1.06 and accessed through the load static method. The above error occurs.

The previously supported PDF version is 1.4, And the 1.6 PDF version has such a problem.

If you change the version of the imported PDF template to 1.4, this problem can be solved.

Of course, it is not necessarily 1.4. The most important issue is a version.
