libabmp

A lightweight C library for reading and writing BMP files, implemented from scratch without external dependencies.

Features

• Supports only 24-bit BMP formats
• Pure C implementation (no external libraries)
• Minimal overhead with direct file I/O

Build Instructions

All Platforms

cmake -B build
cmake --build build

Note: On Windows, ensure MinGW is installed and available in PATH. The library does not compile with MSVC (cl.exe) due to C language feature requirements.

Example Usage

cd example
cmake -B build
cmake --build build
./build/example

The example generates output.bmp using sample images from samples/.
