A fast and free C++ library for creating, parsing and manipulating PDF files and streams.

Documentation | Project Site | NodeJS Wrapper

Prerequisites

  • Compiler: Visual Studio (Windows), GCC/Clang (Linux/macOS)
  • CMake: Download here
  • OpenSSL: Required for PDF2.0 encryption (set PDFHUMMUS_NO_OPENSSL=TRUE to disable)

Project Structure

  • PDFWriter: Main library implementation
  • PDFWriterTesting: Test code for ctest
  • FreeType, LibAesgm, LibJpeg, LibPng, LibTiff, Zlib: Bundled dependencies

Quick Start

bash
# Build
mkdir build && cd build
cmake ..
cmake --build . --config Release

# Test
ctest --test-dir . -C Release

# Install
cmake --install . --prefix ./install --config Release

CMake Options

Option Default Description
PDFHUMMUS_NO_DCT FALSE Exclude DCT decoding support/Detach LibJpeg dependency
PDFHUMMUS_NO_TIFF FALSE Exclude TIFF Images support/Detach LibTiff dependency
PDFHUMMUS_NO_PNG FALSE Exclude PNG Images support/Detatch LibgPng dependency
PDFHUMMUS_NO_OPENSSL FALSE Exclude PDF2.0 encryption/Detach OpenSSL dependency
USE_BUNDLED TRUE Use bundled dependencies
USE_UNBUNDLED_FALLBACK_BUNDLED FALSE Fallback to bundled if system libs not found
BUILD_FUZZING_HARNESS FALSE Enable fuzz testing

Example: cmake .. -DUSE_BUNDLED=FALSE

Using in Your Project

Option 1: CMake FetchContent (Recommended)

cmake
include(FetchContent)
FetchContent_Declare(
  PDFHummus
  GIT_REPOSITORY https://github.com/galkahana/PDF-Writer.git
  GIT_TAG        v4.6.2
  FIND_PACKAGE_ARGS
)
FetchContent_MakeAvailable(PDFHummus)
target_link_libraries(YourTarget PDFHummus::PDFWriter)

Option 2: find_package

cmake
find_package(PDFHummus REQUIRED)
target_link_libraries(YourTarget PDFHummus::PDFWriter)

Option 3: Copy Sources

Simply copy the source folders to your project and include them directly.
