YuvImage

public class YuvImage
extends Object

java.lang.Object
↳	android.graphics.YuvImage

YuvImage contains YUV data and provides a method that compresses a region of the YUV data to a Jpeg. The YUV data should be provided as a single byte array irrespective of the number of image planes in it. Currently only ImageFormat.NV21 and ImageFormat.YUY2 are supported. To compress a rectangle region in the YUV data, users have to specify the region by left, top, width and height.

Summary

Public constructors
`YuvImage(byte[] yuv, int format, int width, int height, int[] strides)` Construct an YuvImage.

Public methods
`boolean`	`compressToJpeg(Rect rectangle, int quality, OutputStream stream)` Compress a rectangle region in the YuvImage to a jpeg.
`int`	`getHeight()`
`int[]`	`getStrides()`
`int`	`getWidth()`
`byte[]`	`getYuvData()`
`int`	`getYuvFormat()`

Inherited methods

From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

YuvImage

Added in API level 8

YuvImage (byte[] yuv, 
                int format, 
                int width, 
                int height, 
                int[] strides)

Construct an YuvImage.

Parameters
`yuv`	`byte`: The YUV data. In the case of more than one image plane, all the planes must be concatenated into a single byte array.
`format`	`int`: The YUV data format as defined in `ImageFormat`.
`width`	`int`: The width of the YuvImage.
`height`	`int`: The height of the YuvImage.
`strides`	`int`: (Optional) Row bytes of each image plane. If yuv contains padding, the stride of each image must be provided. If strides is null, the method assumes no padding and derives the row bytes by format and width itself.

Throws
`IllegalArgumentException`	if format is not support; width or height <= 0; or yuv is null.

Public methods

compressToJpeg

Added in API level 8

boolean compressToJpeg (Rect rectangle, 
                int quality, 
                OutputStream stream)

Compress a rectangle region in the YuvImage to a jpeg. Only ImageFormat.NV21 and ImageFormat.YUY2 are supported for now.

Parameters
`rectangle`	`Rect`: The rectangle region to be compressed. The medthod checks if rectangle is inside the image. Also, the method modifies rectangle if the chroma pixels in it are not matched with the luma pixels in it.
`quality`	`int`: Hint to the compressor, 0-100. 0 meaning compress for small size, 100 meaning compress for max quality.
`stream`	`OutputStream`: OutputStream to write the compressed data.

Returns
`boolean`	True if the compression is successful.

Throws
`IllegalArgumentException`	if rectangle is invalid; quality is not within [0, 100]; or stream is null.

getHeight

Added in API level 8

int getHeight ()

Returns
`int`	the height of the image.

getStrides

Added in API level 8

int[] getStrides ()

Returns
`int[]`	the number of row bytes in each image plane.

getWidth

Added in API level 8

int getWidth ()

Returns
`int`	the width of the image.

getYuvData

Added in API level 8

byte[] getYuvData ()

Returns
`byte[]`	the YUV data.

getYuvFormat

Added in API level 8

int getYuvFormat ()

Returns
`int`	the YUV format as defined in `ImageFormat`.
