public class Matrix
extends Object

java.lang.Object
↳	android.graphics.Matrix

The Matrix class holds a 3x3 matrix for transforming coordinates.

Summary

Constants
`int`	`MPERSP_0`
`int`	`MPERSP_1`
`int`	`MPERSP_2`
`int`	`MSCALE_X`
`int`	`MSCALE_Y`
`int`	`MSKEW_X`
`int`	`MSKEW_Y`
`int`	`MTRANS_X`

Fields
`public static final Matrix`	`IDENTITY_MATRIX` The identity matrix.

Public constructors
`Matrix()` Create an identity matrix
`Matrix(Matrix src)` Create a matrix that is a (deep) copy of src

Public methods
`final void`	`dump(PrintWriter pw)` Dumps a human-readable shortened string of the matrix into the given stream
`boolean`	`equals(Object obj)` Returns true iff obj is a Matrix and its values equal our values.
`void`	`getValues(float[] values)` Copy 9 values from the matrix into the array.
`int`	`hashCode()` Returns a hash code value for the object.
`boolean`	`invert(Matrix inverse)` If this matrix can be inverted, return true and if inverse is not null, set inverse to be the inverse of this matrix.
`boolean`	`isAffine()` Gets whether this matrix is affine.
`boolean`	`isIdentity()` Returns true if the matrix is identity.
`void`	`mapPoints(float[] dst, int dstIndex, float[] src, int srcIndex, int pointCount)` Apply this matrix to the array of 2D points specified by src, and write the transformed points into the array of points specified by dst.
`void`	`mapPoints(float[] dst, float[] src)` Apply this matrix to the array of 2D points specified by src, and write the transformed points into the array of points specified by dst.
`void`	`mapPoints(float[] pts)`
