public final class FileTransformFactory
extends Object

java.lang.Object
↳	androidx.camera.view.transform.FileTransformFactory

Factory for extracting transform info from image files.

This class is for extracting a OutputTransform from an image file saved by ImageCapture. The OutputTransform represents the transform being applied to the original camera buffer, which can be used by CoordinateTransform to transform coordinates between UseCases.

Public methods

getOutputTransform

public OutputTransform getOutputTransform (ContentResolver contentResolver, 
                Uri uri)

Extracts transform info from the given Uri.

Parameters
`contentResolver`	`ContentResolver`
`uri`	`Uri`

Returns
`OutputTransform`

Throws
`IOException`

getOutputTransform

public OutputTransform getOutputTransform (InputStream inputStream)

Extracts transform info from the given InputStream.

Parameters
`inputStream`	`InputStream`

Returns
`OutputTransform`

Throws
`IOException`

getOutputTransform

public OutputTransform getOutputTransform (File file)

Extracts transform info from the given File.

Parameters
`file`	`File`

Returns
`OutputTransform`

Throws
`IOException`

isUsingExifOrientation

public boolean isUsingExifOrientation ()

Whether the factory respects the exif of the image file.

Returns
`boolean`

setUsingExifOrientation

public void setUsingExifOrientation (boolean usingExifOrientation)

Whether to include the ExifInterface.TAG_ORIENTATION. By default, this value is false, e.g. loading image with BitmapFactory does not apply the exif orientation to the loaded Bitmap. Only set this if the exif orientation is applied to the loaded file. For example, if the image is loaded by a 3P library that automatically applies exif orientation.

Parameters
`usingExifOrientation`	`boolean`
