opencv_ffi 1.0.0

An FFI implementation of OpenCV for Dart

OpenCV FFI

This package contains an ffi-based implementation of OpenCV in Dart. That is, OpenCV itself is bundled in this repository (as a submodule, in src/opencv), and must be built first for this package to work.

You can compile OpenCV on any platform, but the process is much simpler on Windows:

1. Install Visual Studio. You'll likely already have done this since it's required for Flutter for Windows.
2. Run winbuild.bat. You'll need to run it with cmake in your path. You can use the Developer Command Prompt for Visual Studio, which you can find in your path.
3. OpenCV will be compiled and a few DLLs will be placed in dist. This should only take around 5 minutes.
4. Copy the DLLs to your package's root directory or in your PATH, as Dart/Pub won't be able to find them otherwise.

Usage

import "package:opencv_ffi/opencv_ffi.dart";

void main() async {
  final camera = Camera(0);
  try {
    while (true) {
      camera.showFrame();
    }
  } finally {
    camera.dispose();    
  }
}
