You're in luck. I just recently submitted a PR for including an image capture() feature in the Android version. If you clone the openalpr-with-image-capture branch of this repo, you should have access to the capture functionality which you are seeking. You would be able to do something like this with your onPlateRecognized():

  onPlateRecognized({ plate, confidence }) {
    if (confidence > 0.9) {
      if (this.license !== plate) { // Only take a picture if the plate recognized is different from the recent one
         this.license = plate;
         this.takePicture();
       }
    }
  }
}

takePicture() {
  this.cameraRef.capture()
  .then((data) => ....)
  .catch((e) => ...)
}

I will look into adding this feature into iOS when the time comes. In the meantime, you're welcome to get started on a new branch! Just refer to react-native-camera and you'll be tip top!

I added that functionality for iOS in this PR

Here is how to use it:

this. cameraRef.takePicture().then(
        uri => {
              console.log(`uri for the image ${uri}`;
        },
        error => {
              console.log(`Error : ${error}`;
        }
      );

Hi @franck-nadeau,

I get CameraManager.takePicture is not a function error and when i log the ref i actually can't see the function.

Hello.

A few things,

• first you need to be on master because there hasn't been a release for about 2 years.

 "react-native-openalpr": "RobertSasak/react-native-openalpr#master",

• second, this will only work on iOS.
• third you should use the Camera.takePicture() helper function that I added.

Let me know if this still does not work for you.

@franck-nadeau Thanks for the quick answer,

• This is on my package.json : "react-native-openalpr": "RobertSasak/react-native-openalpr#master",
• I am working on ios.

After calling the function from the module not the ref, i get;

TypeError: _reactNativeOpenalpr.default.takePicture is not a function.

Also when i call it with Camera.prototype.takePicture, i get;

TypeError: CameraManager.takePicture is not a function

I am not sure why that is. It is working fine off my own repo (and my PR was merged in this one too). Anyway, you could try using it as I am:

"react-native-openalpr": "franck-nadeau/react-native-openalpr#master",

Here is my code for your info.

  onPlateRecognized({ plate, confidence }) {
    if (confidence > 90) {
      // We got a good match, lets take a screenshot of it.
      this.refs.camera.takePicture().then(
        uri => {
        },
        error => {
        }
      );
    }
  }

render() {
...
 <Camera
          ref="camera"
....

Can someone update the example in the repo with this method too ? I can't manage to make it work , i would appreciate a working example. Thank you
