 final static ByteArray )>imageToJpegByteArray(<Error class: unknown class> image)

android.media.Image to JPEG byte array.

 final static ByteArray cropByteArray(ByteArray data, Rect cropRect)

Crops byte array with given android.graphics.Rect.

isAspectRatioValid
```
 final Boolean isAspectRatioValid(Rational aspectRatio)
```
True if the given aspect ratio is meaningful.

isAspectRatioValid
```
 final Boolean isAspectRatioValid(Size sourceSize, Rational aspectRatio)
```
True if the given aspect ratio is meaningful and has effect on the given size.

computeCropRectFromAspectRatio
```
 final static Rect computeCropRectFromAspectRatio(Size sourceSize, Rational aspectRatio)
```
Calculates crop rect with the specified aspect ratio on the given size. Assuming the rect is at the center of the source.
