Tesseract 4.1.0

Click "Capture" button to capture image from camera. Tesseract recognizes text from image and shows output(OCR result) on the screen.
Click "Off" button to turn off device camera.

Main Scene

Description

Recognize from a Texture
```
  Recoginze(texture);
```

Save the screenshot to Gallery

 NativeGallery.Permission permission = NativeGallery.SaveImageToGallery(texture, "CameraTest", "CaptureImage.png", (success, path) => Debug.Log("Media save result: " + success + " " + path));

If you want to save screenshot to gallery, you have to build project. (Unity-Remote-5 doesn't work.)
You only need to refer to ./Assets/Scripts/TesseractDemoScript.cs.
