PDFSource class abstract

Represents a base class of PDF document source.

This abstract class defines the interface for various sources of PDF documents, such as network, asset, file, or memory. Subclasses should implement the getBytes method to provide the specific logic for retrieving the PDF data.

See also:

• URLPDFSource, for fetching a PDF from a URL.
• AssetPDFSource, for loading a PDF from app assets.
• FilePDFSource, for loading a PDF from a local file.
• BytePDFSource, for loading a PDF stored in memory.
