The GoDoc for unipdf provides a detailed breakdown of the API and documentation for packages, types and methods. https://godoc.org/github.com/unidoc/unipdf

Overview of Major Packages

The API is composed of a few major packages:

- common: Provides common shared types such as Logger and utilities to check
  license validity.

- core: The core package defines the primitive PDF object types and handles
  the file reading I/O and parsing the primitive objects.

- model: The model package builds on the core package, to represent the PDF as
  a structured model of the PDF primitive types. It has a reader and a writer to
  read and process a PDF file based on the structured model. This serves as a basis
  to perform a number of numerous tasks and can be used to work with a PDF in a
  medium to high level interface, although it does require an understanding of the
  PDF format and structure.

- creator: The PDF creator makes it easy to create new PDFs or modify existing
  PDFs. It can also enable loading a template PDF, adding text/images and
  generating an output PDF. It can be used to add text, images, and generate text
  and graphical reports. It is designed with simplicity in mind, with the goal of
  making it easy to create reports without needing any knowledge about the PDF
  format or specifications.

- extractor: Package extractor is used for quickly extracting PDF content
  through a simple interface. Currently offers functionality for extracting textual
  content.
