Question

I’m trying to create a camera activity for taking photos to be OCR’d. Here’s what I wish to accomplish:

1. A resizable box in the middle of the camera preview to indicate which particular area will be created into a Bitmap and processed by the OCR engine.
2. Continuous autofocus (done)

I’m using tesseract btw.

If anyone would care to point me to some reference / examples / tutorials, that would be great.
