ImageProxy


public interface ImageProxy extends AutoCloseable


An image proxy which has a similar interface as android.media.Image.

Summary

Nested types

public interface ImageProxy.PlaneProxy

Public methods

abstract void

Closes the underlying android.media.Image.

abstract @NonNull Rect

Returns the crop rectangle.

abstract int

Returns the image format.

abstract int

Returns the image height.

abstract @Nullable Image

Returns the android Image.

abstract @NonNull ImageInfo

Returns the ImageInfo.

abstract @NonNull ImageProxy.PlaneProxy[]

Returns the array of planes.

abstract int

Returns the image width.

abstract void

Sets the crop rectangle.

default @NonNull Bitmap

abstract @NonNull Rect getCropRect()

Returns the crop rectangle.

getFormat

Added in 1.0.0
abstract int getFormat()

Returns the image format.

The image format can be one of the ImageFormat or PixelFormat constants.

getHeight

Added in 1.0.0
abstract int getHeight()

Returns the image height.

getImage

Added in 1.0.0
@ExperimentalGetImage
abstract @Nullable Image getImage()

Returns the android Image.

If the ImageProxy is a wrapper for an android Image, it will return the Image. It is possible for an ImageProxy to wrap something that isn't an Image. If that's the case then it will return null.

The returned image should not be closed by the application. Instead it should be closed by the ImageProxy, which happens, for example, on return from the ImageAnalysis.Analyzer function. Destroying the ImageAnalysis will close the underlying android.media.ImageReader. So an Image obtained with this method will behave as such.

Returns
@Nullable Image

the android image.

abstract @NonNull ImageInfo getImageInfo()

Returns the ImageInfo.

getPlanes

Added in 1.0.0
abstract @NonNull ImageProxy.PlaneProxy[] getPlanes()

Returns the array of planes.

toBitmap

Added in 1.3.0
default @NonNull Bitmap toBitmap()

Converts ImageProxy to Bitmap.

The supported ImageProxy format is YUV_420_888, JPEG or RGBA_8888. If format is invalid, an IllegalArgumentException will be thrown. If the conversion to bimap failed, an UnsupportedOperationException will be thrown.

Returns
@NonNull Bitmap

Bitmap instance.
