Description
Captures a still image.The image is returned a JPEG image as container value on Mac and BMP on Windows.
Added Windows support with plugin version 6.5.
May require running the preview for some time as we capture only current preview frame on Windows. If no frame is yet available, the function returns an error.
If you need content detection, you can always get current frame with AVRecorder.CaptureStillPhoto and pass it to OCR.SetImage for text recognition or Barcode.Detect to find different barcodes.
