Class Matrix

Sets Matrix to:

 | scaleX  skewX transX |
 |  skewY scaleY transY |
 |  pers0  pers1  pers2 |

Returns

Matrix constructed from parameters

Sets Matrix to scale by (sx, sy). Returned matrix is:

  | sx  0  0 |
  |  0 sy  0 |
  |  0  0  1 |

Returns

Matrix with scale

Sets Matrix to translate by (dx, dy). Returned matrix is:

  | 1 0 dx |
  | 0 1 dy |
  | 0 0  1 |

Returns

Matrix with translation

Returns one matrix value.

Sets Matrix value.

Sets all values from parameters. Sets matrix to:

 | scaleX  skewX transX |
 |  skewY scaleY transY |
 | persp0 persp1 persp2 |

Sets Matrix to identity; which has no effect on mapped Point. Sets Matrix to:

  | 1 0 0 |
  | 0 1 0 |
  | 0 0 1 |

Also called setIdentity(); use the one that provides better inline documentation.

Sets Matrix to translate by (dx, dy).

Sets Matrix to scale by sx and sy, about a pivot point at (px, py). The pivot point is unchanged when mapped with Matrix.

Sets Matrix to rotate by degrees about a pivot point at (px, py). The pivot point is unchanged when mapped with Matrix. Positive degrees rotates clockwise.

Sets Matrix to rotate by sinValue and cosValue, about a pivot point at (px, py). The pivot point is unchanged when mapped with Matrix. Vector (sinValue, cosValue) describes the angle of rotation relative to (0, 1). Vector length specifies scale.

Sets Matrix to skew by kx and ky, about a pivot point at (px, py). The pivot point is unchanged when mapped with Matrix.

Sets Matrix to Matrix a multiplied by Matrix b. Either a or b may be this.

Given:

     | A B C |      | J K L |
 a = | D E F |, b = | M N O |
     | G H I |      | P Q R |

sets Matrix to:

         | A B C |   | J K L |   | AJ+BM+CP AK+BN+CQ AL+BO+CR |
 a * b = | D E F | * | M N O | = | DJ+EM+FP DK+EN+FQ DL+EO+FR |
         | G H I |   | P Q R |   | GJ+HM+IP GK+HN+IQ GL+HO+IR |

Preconcats the matrix with the specified scale. M' = M * S(sx, sy)

Postconcats the matrix with the specified scale. M' = S(sx, sy, px, py) * M

Preconcats the matrix with the specified skew. M' = M * K(kx, ky, px, py)

Preconcats the matrix with the specified matrix. M' = M * other

Postconcats the matrix with the specified translation. M' = T(dx, dy) * M

Postconcats the matrix with the specified scale. M' = S(sx, sy, px, py) * M

Postconcats the matrix with the specified rotation. M' = R(degrees, px, py) * M

Postconcats the matrix with the specified skew. M' = K(kx, ky, px, py) * M

Postconcats the matrix with the specified matrix. M' = other * M
