ColorMatrixColorFilter
public
class
ColorMatrixColorFilter
extends ColorFilter
A color filter that transforms colors through a 4x5 color matrix. This filter
can be used to change the saturation of pixels, convert from YUV to RGB, etc.

Public constructors
ColorMatrixColorFilter
public ColorMatrixColorFilter (ColorMatrix matrix)
Create a color filter that transforms colors through a 4x5 color matrix.
| Parameters |
|---|
matrix |
ColorMatrix: 4x5 matrix used to transform colors. It is copied into
the filter, so changes made to the matrix after the filter
is constructed will not be reflected in the filter.
This value cannot be null. |
ColorMatrixColorFilter
public ColorMatrixColorFilter (float[] array)
Create a color filter that transforms colors through a 4x5 color matrix.
| Parameters |
|---|
array |
float: Array of floats used to transform colors, treated as a 4x5
matrix. The first 20 entries of the array are copied into
the filter. See ColorMatrix.
This value cannot be null. |
Public methods
getColorMatrix
public void getColorMatrix (ColorMatrix colorMatrix)
Copies the ColorMatrix from the filter into the passed ColorMatrix.
| Parameters |
|---|
colorMatrix |
ColorMatrix: Set to the current value of the filter's ColorMatrix. |
