## Matrix class

Encapsulates a 3-by-3 affine matrix that represents a geometric transform. This class cannot be inherited.

```csharp
public sealed class Matrix : IDisposable
```

## Constructors

| Name | Description |
| --- | --- |
| [Matrix](matrix/#constructor)() | Initializes a new instance of the Matrix class as the identity matrix. |
| [Matrix](matrix/#constructor_2)(Rectangle, Point[]) | Initializes a new instance of the `Matrix` class to the geometric transform defined by the specified rectangle and array of points. |
| [Matrix](matrix/#constructor_3)(RectangleF, PointF[]) | Initializes a new instance of the `Matrix` class to the geometric transform defined by the specified rectangle and array of points. |
| [Matrix](matrix/#constructor_1)(float, float, float, float, float, float) | Initializes a new instance of the Matrix class with the specified elements. |

## Properties
