Matrix

Matrix provides operations for 2x3 matrix.
Methods

Multiply the two matrix.
Parameters:
Name
Type
Description
m1
Array
left matrix
m2
Array
right matrix
Returns: Type: Array

Scale operation.
Parameters:
Name
Type
Description
out
Array
the result of the scale operation
m
Array
the matrix to scale
v
Array
scale vector [sx, sy]
Returns: Type: Array

Rotation operation.
Parameters:
Name
Type
Description
out
Array
the result of the rotate operation
m
Array
the matrix to rotate
radian
Number
rotation radian
Returns: Type: Array

Translation operation.
Parameters:
Name
Type
Description
out
Array
the result of the translation operation
m
Array
the matrix to translate
radian
Number
translation vector [ x, y ]
Returns: Type: Array

Perform translation, rotation and scale operations. All operations are configured and stored in actions, the supported operations in actions attribute are: 't' (translate), 's' (scale), 'r' (rotate). Operations can be combined in any combination. For example:
[
[ 't', x, y ], // t for translate, x for offset on x-axis direction, y for offset in y-axis direction
[ 's', sx, sy ], // s for scale, sx for scale on x-axis direction, sy for scale on y-axis direction
[ 'r', radian] // r for rotate,radian for the radians of the rotation
]
Parameters:
Name
Type
Description
m
Array
the matrix to transform
actions
Array
operation setting
Returns: Type: Array
