array $pages = array() (line 120)

Pages collection

- var: - array of Zend_Pdf_Page object
- access: public
- todo: implement it as a class, which supports ArrayAccess and Iterator interfaces, to provide incremental parsing and pages tree updating. That will give good performance and memory (PDF size) benefits.

Methods

Zend_Pdf load ([string $source = null], [integer $revision = null])

- string $source

static pdfDate (line 597)

Convert date to PDF format (it's close to ASN.1 (Abstract Syntax Notation One) defined in ISO/IEC 8824).

- todo: This really isn't the best location for this method. It should probably actually exist as Zend_Pdf_Element_Date or something like that.
- todo: Address the following E_STRICT issue: PHP Strict Standards: date(): It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

string pdfDate ([integer $timestamp = null])

- integer $timestamp: (optional) If omitted, uses the current time.

- access: public
- throws: Zend_Pdf_Exception
