ABOUT

About these examples.

This collection showcases class diagrams for PDF toolkits that handle operations such as text extraction, indexing, and graphics rendering. Each example breaks down the architecture of a PDF toolkit, making it easy to understand how classes like PdfDocument, PdfPage, and PdfRenderer interact.

Use these examples as starting points for your own PDF library design, or generate a custom diagram tailored to your toolkit using our AI UML class diagram generator.

HOW TO

Make one yourself.

  1. 1

    Define core classes

    Identify the main entities—Documents, Pages, Streams, Renderers, etc.

  2. 2

    Establish relationships

    Show inheritance from a base PdfObject or interfaces like ITextExtractor.

  3. 3

    Add attributes and methods

    Populate classes with key fields like `fileName: String` and operations `extractText(): String`.

  4. 4

    Organize into packages

    Group classes into logical packages such as `core`, `filters`, and `rendering`.

  5. 5

    Generate and refine

    Use the diagram generator, then tweak layout and add notes for clarity.

FAQ

Frequently asked questions
