Metadata and Structure
The PDF file starts with metadata and viewer preferences, indicating it's a structured document. It defines the document's properties and how it should be displayed.
Content Streams
The PDF includes several content streams containing encoded text and image data. These streams define the visual elements of the document, such as text layout, fonts, and image rendering.
Font and ProcSet Definitions
