Method Detail

• hasCameras

   static boolean hasCameras(@NonNull() Context context)

  Determines whether the device has valid camera sensors, so the librarycan be used.

  Parameters:

  context - a valid Context

• hasCameraFacing

   static boolean hasCameraFacing(@NonNull() Context context, @NonNull() Facing facing)

  Determines whether the device has a valid camera sensor with the givenFacing value, so that a session can be started.

  Parameters:

  context - a valid context

  facing - either BACK or FRONT

• writeToFile

  @Nullable()@WorkerThread() static File writeToFile(@NonNull() Array<byte> data, @NonNull() File file)

  Simply writes the given data to the given file. It is done synchronously. If you arerunning on the UI thread, please use writeToFile and pass a file callback.If any error is encountered, this returns null.

  Parameters:

  data - the data to be written

  file - the file to write into

• writeToFile

   static void writeToFile(@NonNull() Array<byte> data, @NonNull() File file, @NonNull() FileCallback callback)

  Writes the given data to the given file in a background thread, returning on theoriginal thread (typically the UI thread) once writing is done.If some error is encountered, the FileCallback will return null instead of theoriginal file.

  Parameters:

  data - the data to be written

  file - the file to write into

  callback - a callback

• decodeBitmap

  @Nullable()@WorkerThread() static Bitmap decodeBitmap(@NonNull() Array<byte> source)

  Decodes an input byte array and outputs a Bitmap that is ready to be displayed.The difference with decodeByteArray is that this cares about orientation, reading it from the EXIF header.

  Parameters:

  source - a JPEG byte array

• decodeBitmap

   static void decodeBitmap(@NonNull() Array<byte> source, @NonNull() BitmapCallback callback)

  Decodes an input byte array and outputs a Bitmap that is ready to be displayed.The difference with decodeByteArray is that this cares about orientation, reading it from the EXIF header.This is executed in a background thread, and returns the result to the original thread.

  Parameters:

  source - a JPEG byte array

  callback - a callback to be notified

• decodeBitmap

   static void decodeBitmap(@NonNull() Array<byte> source, int maxWidth, int maxHeight, @NonNull() BitmapCallback callback)

  Decodes an input byte array and outputs a Bitmap that is ready to be displayed.The difference with decodeByteArray is that this cares about orientation, reading it from the EXIF header.This is executed in a background thread, and returns the result to the original thread.The image is also downscaled taking care of the maxWidth and maxHeight arguments.

  Parameters:

  source - a JPEG byte array

  maxWidth - the max allowed width

  maxHeight - the max allowed height

  callback - a callback to be notified

• decodeBitmap

   static void decodeBitmap(@NonNull() Array<byte> source, int maxWidth, int maxHeight, @NonNull() BitmapFactory.Options options, @NonNull() BitmapCallback callback)

  Decodes an input byte array and outputs a Bitmap that is ready to be displayed.The difference with decodeByteArray is that this cares about orientation, reading it from the EXIF header.This is executed in a background thread, and returns the result to the original thread.The image is also downscaled taking care of the maxWidth and maxHeight arguments.

  Parameters:

  source - a JPEG byte array

  maxWidth - the max allowed width

  maxHeight - the max allowed height

  options - the options to be passed to decodeByteArray

  callback - a callback to be notified

• decodeBitmap

  @Nullable()@WorkerThread() static Bitmap decodeBitmap(@NonNull() Array<byte> source, int maxWidth, int maxHeight)

  Decodes an input byte array and outputs a Bitmap that is ready to be displayed.The difference with decodeByteArray is that this cares about orientation, reading it from the EXIF header.The image is also downscaled taking care of the maxWidth and maxHeight arguments.

  Parameters:

  source - a JPEG byte array

  maxWidth - the max allowed width

  maxHeight - the max allowed height

• decodeBitmap

  @Nullable()@WorkerThread() static Bitmap decodeBitmap(@NonNull() Array<byte> source, int maxWidth, int maxHeight, @NonNull() BitmapFactory.Options options)

  Decodes an input byte array and outputs a Bitmap that is ready to be displayed.The difference with decodeByteArray is that this cares about orientation, reading it from the EXIF header.The image is also downscaled taking care of the maxWidth and maxHeight arguments.

  Parameters:

  source - a JPEG byte array

  maxWidth - the max allowed width

  maxHeight - the max allowed height

  options - the options to be passed to decodeByteArray
