Public constructors
RggbChannelVector
public 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
public 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
public 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
public float getBlue ()
Get the blue component.
Returns | |
---|---|
float |
a floating point value (guaranteed to be finite) |
getComponent
public 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
public float getGreenEven ()
Get the green (even rows) component.
Returns | |
---|---|
float |
a floating point value (guaranteed to be finite) |
getGreenOdd
public float getGreenOdd ()
Get the green (odd rows) component.
Returns | |
---|---|
float |
a floating point value (guaranteed to be finite) |
getRed
public float getRed ()
Get the red component.
Returns | |
---|---|
float |
a floating point value (guaranteed to be finite) |
hashCode
public 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 inequals
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
method, then calling thehashCode
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
method, then calling thehashCode
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.
Returns | |
---|---|
int |
a hash code value for this object. |
toString
public 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 |
