PopplerDocument

PopplerDocument is a fundamental object within the Poppler PDF rendering library. It represents a single PDF document loaded into memory. When you use Poppler to open a PDF file, an instance of PopplerDocument is created to hold all the information about that document, including its pages, metadata, and internal structure.

This object acts as the primary interface for interacting with the PDF content. Through the PopplerDocument object, developers can access individual pages, extract text, retrieve images, and obtain information such as the document's title, author, and creation date. It facilitates navigation through the document, allowing access to pages by their index.

Key functionalities provided by PopplerDocument include the ability to determine the number of pages in the document and to obtain a specific page object for further processing. It is the gateway to all other rendering and extraction operations. PopplerDocument itself does not render the PDF; rather, it provides the structured data representation of the PDF document that other Poppler components use for rendering, annotation handling, and text extraction. Managing the lifecycle of a PopplerDocument is crucial for proper memory management, ensuring that resources are released when the document is no longer needed.
