PopplerPage

PopplerPage is a fundamental component of the Poppler PDF rendering library. It represents a single page within a PDF document. When Poppler is used to open and process a PDF file, it typically creates a collection of PopplerPage objects, each corresponding to one page in the original document.

Developers interact with PopplerPage to access and manipulate the content of a specific page. This includes retrieving text, vector graphics, and images. PopplerPage also provides methods for rendering the page into various image formats, such as PNG or JPEG, allowing for display or further processing. It serves as the interface through which one can obtain information about page dimensions, rotation, and other page-specific attributes.

Key functionalities associated with PopplerPage include text extraction, where the library attempts to identify and return the textual content of the page. Rendering capabilities allow the page to be drawn onto a surface, enabling visual representation. Transformations like rotation or scaling can often be applied to the PopplerPage before rendering. The library manages the internal representation of the page's content, and PopplerPage is the abstraction that exposes this content to the application. In essence, PopplerPage is the gateway to interacting with the visual and textual elements of an individual page within a PDF document when using the Poppler library.
