Public constructors

RggbChannelVector

Added in API level 21

RggbChannelVector (float red, 
                float greenEven, 
                float greenOdd, 
                float blue)

Create a new RggbChannelVector from an RGGB 2x2 pixel.

All pixel values are considered normalized within [0.0f, 1.0f] (i.e. 1.0f could be linearized to 255 if converting to a non-floating point pixel representation).

All arguments must be finite; NaN and infinity is not allowed.

Parameters
`red`	`float`: red pixel
`greenEven`	`float`: green pixel (even row)
`greenOdd`	`float`: green pixel (odd row)
`blue`	`float`: blue pixel

Throws
`IllegalArgumentException`	if any of the arguments were not finite

Public methods

copyTo

Added in API level 21

void copyTo (float[] destination, 
                int offset)

Copy the vector into the destination in the order [R, Geven, Godd, B].

Parameters
`destination`	`float`: an array big enough to hold at least `.COUNT` elements after the `offset`
`offset`	`int`: a non-negative offset into the array

Throws
`NullPointerException`	If `destination` was `null`
`ArrayIndexOutOfBoundsException`	If there's not enough room to write the elements at the specified destination and offset.

equals

Added in API level 21

boolean equals (Object obj)

Check if this RggbChannelVector is equal to another RggbChannelVector.

Two vectors are only equal if and only if each of the respective elements is equal.

Parameters
`obj`	`Object`: the reference object with which to compare.

Returns
`boolean`	`true` if the objects were equal, `false` otherwise

getBlue

Added in API level 21

float getBlue ()

Get the blue component.

Returns
`float`	a floating point value (guaranteed to be finite)

getComponent

Added in API level 21

float getComponent (int colorChannel)

Get the component by the color channel index.

colorChannel must be one of RED, GREEN_EVEN, GREEN_ODD, BLUE.

Parameters
`colorChannel`	`int`: greater or equal to `0` and less than `COUNT`

Returns
`float`	a floating point value (guaranteed to be finite)

Throws
`IllegalArgumentException`	if `colorChannel` was out of range

getGreenEven

Added in API level 21

float getGreenEven ()

Get the green (even rows) component.

Returns
`float`	a floating point value (guaranteed to be finite)

getGreenOdd

Added in API level 21

float getGreenOdd ()

Get the green (odd rows) component.

Returns
`float`	a floating point value (guaranteed to be finite)

getRed

Added in API level 21

float getRed ()

Get the red component.

Returns
`float`	a floating point value (guaranteed to be finite)

hashCode

Added in API level 21

int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)

Returns
`int`	a hash code value for this object.

toString

Added in API level 21

String toString ()

Return the RggbChannelVector as a string representation.

"RggbChannelVector{R:%f, G_even:%f, G_odd:%f, B:%f}", where each %f respectively represents one of the the four color channels.

Returns
`String`	string representation of `RggbChannelVector`
