Field Detail

MINIMUM_GAIN_FACTOR

public static final float MINIMUM_GAIN_FACTOR
Deprecated. 
The smallest gain factor in this map.

All values in this map will be at least this large.

Constructor Detail

LensShadingMap

public LensShadingMap()
Deprecated. 

Method Detail

getRowCount

public abstract int getRowCount()
Deprecated. 
Get the number of rows in this map.
Returns:
The number of rows.

getColumnCount

public abstract int getColumnCount()
Deprecated. 
Get the number of columns in this map.
Returns:
The number of columns.

getGainFactorCount

public abstract int getGainFactorCount()
Deprecated. 
Get the total number of gain factors in this map.

A single gain factor contains exactly one color channel. Use with copyGainFactors(float[], int) to allocate a large-enough array.

Returns:
The total number of gain factors.

getGainFactor

public abstract float getGainFactor(int colorChannel,
                                    int column,
                                    int row)
Deprecated. 
Get a single color channel gain factor from this lens shading map by its row and column.

The rows must be within the range [0, getRowCount()), the column must be within the range [0, getColumnCount()), and the color channel must be within the range [0, ).

The channel order is [R, Geven, Godd, B], where Geven is the green channel for the even rows of a Bayer pattern, and Godd is the odd rows.

Parameters:
colorChannel - color channel from [R, Geven, Godd, B]
column - within the range [0, getColumnCount())
row - within the range [0, getRowCount())
Returns:
a gain factor ≥ 1.0f
Throws:
IllegalArgumentException - if any of the parameters was out of range

RggbChannelVector.RED, RggbChannelVector.GREEN_EVEN, RggbChannelVector.GREEN_ODD, RggbChannelVector.BLUE, getRowCount(), getColumnCount()

getGainFactorVector

public abstract RggbChannelVector getGainFactorVector(int column,
                                                      int row)
Deprecated. 
Get a gain factor vector from this lens shading map by its row and column.

The rows must be within the range [0, getRowCount()), the column must be within the range [0, getColumnCount()).

Parameters:
column - within the range [0, getColumnCount())
row - within the range [0, getRowCount())
Returns:
an RggbChannelVector where each gain factor ≥ 1.0f
Throws:
IllegalArgumentException - if any of the parameters was out of range
See Also:
getRowCount(), getColumnCount()

copyGainFactors

public abstract void copyGainFactors(float[] destination,
                                     int offset)
Deprecated. 
Copy all gain factors in row-major order from this lens shading map into the destination.

Each gain factor will be ≥ MINIMUM_GAIN_FACTOR.

Parameters:
destination - an array big enough to hold at least RggbChannelVector.COUNT elements after the offset
offset - a non-negative offset into the array
Throws:
NullPointerException - If destination was null
IllegalArgumentException - If offset was negative
ArrayIndexOutOfBoundsException - If there's not enough room to write the elements at the specified destination and offset.

equals

public abstract boolean equals(Object obj)
Deprecated. 
Check if this LensShadingMap is equal to another LensShadingMap.

Two lens shading maps are equal if and only if they have the same rows/columns, and all of their elements are equal.

Overrides:
equals in class Object
Returns:
true if the objects were equal, false otherwise

hashCode

public abstract int hashCode()
Deprecated. 
Overrides:
hashCode in class Object

toString

public abstract String toString()
Deprecated. 
Return the LensShadingMap as a string representation.

"LensShadingMap{R:([%f, %f, ... %f], ... [%f, %f, ... %f]), G_even:([%f, %f, ... %f], ... [%f, %f, ... %f]), G_odd:([%f, %f, ... %f], ... [%f, %f, ... %f]), B:([%f, %f, ... %f], ... [%f, %f, ... %f])}", where each %f represents one gain factor and each [%f, %f, ... %f] represents a row of the lens shading map

Overrides:
toString in class Object
Returns:
string representation of LensShadingMap
