Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public static ScriptIntrinsicHistogram create (RenderScript rs, Element e)

Added in API level 19

Create an intrinsic for calculating the histogram of an uchar or uchar4 image. Supported elements types are U8_4(RenderScript), U8_3(RenderScript), U8_2(RenderScript), U8(RenderScript)

Parameters

rs	The RenderScript context
e	Element type for inputs

Returns

ScriptIntrinsicHistogram

public void forEach (Allocation ain, Script.LaunchOptions opt)

Added in API level 21

Process an input buffer and place the histogram into the output allocation. The output allocation may be a narrower vector size than the input. In this case the vector size of the output is used to determine how many of the input channels are used in the computation. This is useful if you have an RGBA input buffer but only want the histogram for RGB. 1D and 2D input allocations are supported.

Parameters

ain	The input image
opt	LaunchOptions for clipping

public void forEach (Allocation ain)

Added in API level 19

Parameters

ain	The input image

public void forEach_Dot (Allocation ain)

Added in API level 19

Process an input buffer and place the histogram into the output allocation. The dot product of the input channel and the coefficients from 'setDotCoefficients' are used to calculate the output values. 1D and 2D input allocations are supported.

Parameters

ain	The input image

public void forEach_Dot (Allocation ain, Script.LaunchOptions opt)

Added in API level 21

Parameters

ain	The input image
opt	LaunchOptions for clipping

public Script.FieldID getFieldID_Input ()

Added in API level 19

Get a FieldID for the input field of this intrinsic.

Returns

Script.FieldID The FieldID object.

public Script.KernelID getKernelID_Separate ()

Added in API level 19

Get a KernelID for this intrinsic kernel.

Returns

Script.KernelID The KernelID object.

public void setDotCoefficients (float r, float g, float b, float a)

Added in API level 19

Set the coefficients used for the RGBA to Luminocity calculation. The default is {0.299f, 0.587f, 0.114f, 0.f}. Coefficients must be >= 0 and sum to 1.0 or less.

Parameters

r	Red coefficient
g	Green coefficient
b	Blue coefficient
a	Alpha coefficient

public void setOutput (Allocation aout)

Added in API level 19

Set the output of the histogram. 32 bit integer types are supported.

Parameters

aout	The output allocation
