Options for scaling the preview vis-à-vis its container PreviewView.

Summary

Enum values
`PreviewView.ScaleType`	`FILL_CENTER` Scale the preview, maintaining the source aspect ratio, so it fills the entire `PreviewView`, and center it in the view.
`PreviewView.ScaleType`	`FILL_END` Scale the preview, maintaining the source aspect ratio, so it fills the entire `PreviewView`, and align it to the end of the view, which is the bottom right corner in a left-to-right (LTR) layout, or the bottom left corner in a right-to-left (RTL) layout.
`PreviewView.ScaleType`	`FILL_START` Scale the preview, maintaining the source aspect ratio, so it fills the entire `PreviewView`, and align it to the start of the view, which is the top left corner in a left-to-right (LTR) layout, or the top right corner in a right-to-left (RTL) layout.
`PreviewView.ScaleType`	`FIT_CENTER` Scale the preview, maintaining the source aspect ratio, so it is entirely contained within the `PreviewView`, and center it inside the view.
`PreviewView.ScaleType`	`FIT_END` Scale the preview, maintaining the source aspect ratio, so it is entirely contained within the `PreviewView`, and align it to the end of the view, which is the bottom right corner in a left-to-right (LTR) layout, or the bottom left corner in a right-to-left (RTL) layout.
`PreviewView.ScaleType`	`FIT_START` Scale the preview, maintaining the source aspect ratio, so it is entirely contained within the `PreviewView`, and align it to the start of the view, which is the top left corner in a left-to-right (LTR) layout, or the top right corner in a right-to-left (RTL) layout.

Enum values

FILL_CENTER

public static final PreviewView.ScaleType FILL_CENTER

Scale the preview, maintaining the source aspect ratio, so it fills the entire PreviewView, and center it in the view.

This may cause the preview to be cropped if the camera preview aspect ratio does not match that of its container PreviewView.

FILL_END

public static final PreviewView.ScaleType FILL_END

Scale the preview, maintaining the source aspect ratio, so it fills the entire PreviewView, and align it to the end of the view, which is the bottom right corner in a left-to-right (LTR) layout, or the bottom left corner in a right-to-left (RTL) layout.

This may cause the preview to be cropped if the camera preview aspect ratio does not match that of its container PreviewView.

FILL_START

public static final PreviewView.ScaleType FILL_START

Scale the preview, maintaining the source aspect ratio, so it fills the entire PreviewView, and align it to the start of the view, which is the top left corner in a left-to-right (LTR) layout, or the top right corner in a right-to-left (RTL) layout.

This may cause the preview to be cropped if the camera preview aspect ratio does not match that of its container PreviewView.

FIT_CENTER

public static final PreviewView.ScaleType FIT_CENTER

Scale the preview, maintaining the source aspect ratio, so it is entirely contained within the PreviewView, and center it inside the view. The background area not covered by the preview stream will be black or the background of the PreviewView.

Both dimensions of the preview will be equal or less than the corresponding dimensions of its container PreviewView.

FIT_END

public static final PreviewView.ScaleType FIT_END

Scale the preview, maintaining the source aspect ratio, so it is entirely contained within the PreviewView, and align it to the end of the view, which is the bottom right corner in a left-to-right (LTR) layout, or the bottom left corner in a right-to-left (RTL) layout. The background area not covered by the preview stream will be black or the background of the PreviewView.

Both dimensions of the preview will be equal or less than the corresponding dimensions of its container PreviewView.

FIT_START

public static final PreviewView.ScaleType FIT_START

Scale the preview, maintaining the source aspect ratio, so it is entirely contained within the PreviewView, and align it to the start of the view, which is the top left corner in a left-to-right (LTR) layout, or the top right corner in a right-to-left (RTL) layout. The background area not covered by the preview stream will be black or the background of the PreviewView

Both dimensions of the preview will be equal or less than the corresponding dimensions of its container PreviewView.
