npm run create_opencvlib
Result in folder osOpencvWorlds/*/*.tar
npm run create_opencvnode_prebuild
Result in folder opencv/build/bin for windows or in opencv/build/lib for linux and darwin
Create fork of the repo and add necessary changes then create poll request to the repo and i will recreate libs
For example i was able to add method invert recently
Nan::SetMethod(target, "invert", Invert);
Nan::SetMethod(target, "invertAsync", InvertAsync);
NAN_METHOD(Core::Invert) {
FF::syncBinding<CoreBindings::Invert>("Core", "Invert", info);
}
NAN_METHOD(Core::InvertAsync) {
FF::asyncBinding<CoreBindings::Invert>("Core", "Invert", info);
}
static NAN_METHOD(Invert);
static NAN_METHOD(InvertAsync);
class Invert : public CvClassMethodBinding<Mat> {
public:
void createBinding(std::shared_ptr<FF::Value<cv::Mat>> self) {
auto flags = opt<FF::IntConverter>("flags", 0);
auto dst = ret<Mat::Converter>("dst");
executeBinding = [=]() {
cv::invert(self->ref(), dst->ref(), flags->ref());
};
};
};
export function invert(mat: Mat, flags?: number): Mat;
export function invertAsync(mat: Mat, flags?: number): Promise<Mat>;
