\Zend_Pdf_FileParser_Image_Png
Package: Zend_Pdf\FileParser
Abstract base class for Image file parsers.
Provides a library of methods to quickly navigate and extract various data
types (signed and unsigned integers, floating- and fixed-point numbers,
strings, etc.) from the file.
File access is managed via a {@link Zend_Pdf_FileParserDataSource} object.
This allows the same parser code to work with many different data sources:
in-memory objects, filesystem files, etc.
