## Documentation

* `Float2D`: A class containing two `float` values as Vertical and Horizontal coordinates representing a point in a 2D plane.
* `Float3D`: A class containing three `float` values as Vertical, Horizontal and Depth coordinates representing a point in a 3D plane.
* `Path`: A class containing a `float` starting and a `float` ending point for a single dimensional animation as well as duration and the function to control the animation.
* `Path2D`: A class containing a `Float2D` starting and a `Float2D` ending point for a two dimensional animation as well as duration and the function to control the animation.
* `Path3D`: A class containing a `Float3D` starting and a `Float3D` ending point for a three dimensional animation as well as duration and the function to control the animation.
* `Animator`: A class for animating an array of `Path` objects. This class is one of the main classes and starting points of a basic animation.
* `Animator2D`: A class for animating an array of `Path2D` objects. This class is one of the main classes and starting points of a basic animation.
* `Animator2D`: A class for animating an array of `Path3D` objects. This class is one of the main classes and starting points of a basic animation.
* `SafeInvoker`: A class holding a reference to a function to invoke in the correct thread, detected by a `Control` object passed to it. Useful for easier UI manipulations.
* `SafeInvoker`: Same as `SafeInvoker` class but with a generic argument for the function to invoke.

For full documentation of the classes and their members, please take a look at our doxygen page at [falahati.github.io](https://falahati.github.io/WinFormAnimation/doxygen).

## Basic examples
### ONE DIMENSIONAL ANIMATION OF A PROPERTY
Following code animates a property named `Value` of a `ProgressBar` named `pb_progress` in 5 seconds from zero to one hundred:
```C#
new Animator(new Path(0, 100, 5000))
.Play(pb_progress, Animator.KnownProperties.Value);
```

### TWO DIMENSIONAL ANIMATION OF A PROPERTY
Following code animates a `Form` in two paths. First one moves the `Form` from (0, -100) to (100, 200) and second path waits for 3 seconds and then moved the `Form` to its initial location in 2 seconds. (`this` is a `Form`)
```C#
new Animator2D(
new Path2D(0, 100, -100, 200, 5000).ContinueTo(this.Location.ToFloat2D(), 2000, 3000))
.Play(this, Animator2D.KnownProperties.Location);
```

### THREE DIMENSIONAL ANIMATION OF A PROPERTY
Following code animates a property named `CustomColor` of a `Control` named `c_customLabel` in 2 seconds and after a delay of 1 second using the `AnimationFunctions.CubicEaseIn` function and with maximum of 10 frames per second.
```C#
new Animator3D(
new Path3D(Color.Blue.ToFloat3D(), Color.Red.ToFloat3D(), 2000, 1000, AnimationFunctions.CubicEaseIn),
FPSLimiterKnownValues.LimitTen)
.Play(c_customLabel, "CustomColor");
```

### KEYFRAMES
There are extension methods for `Path`, `Path2D`, `Path3D` and their arrays to let you continue the path easily and define the key frames as fast as possible. For example, following code moves a `Control` named `c_control` in a rectangular path infinitely:
```C#
new Animator2D(
new Path2D(new Float2D(100, 100), new Float2D(200, 100), 1000)
.ContinueTo(new Float2D(200, 200), 1000)
.ContinueTo(new Float2D(100, 200), 1000)
.ContinueTo(new Float2D(100, 100), 1000))
{
Repeat = true
}.Play(c_control, Animator2D.KnownProperties.Location);
```

### CALLBACKS
It is possible to define a custom callback as frame handler as well as defining a call back to handle the end of the animation. Following example will call a method named `CustomSetMethod` for setting new values and handle the frames, and starts the animation in reverse path after its end for one more time:

```C#
var animator = new Animator(new Path(100, 200, 1000).ContinueTo(400, 500));
animator.Play(new SafeInvoker(CustomSetMethod), new SafeInvoker(() =>
{
animator.Paths = animator.Paths.Select(path => path.Reverse()).Reverse().ToArray();
animator.Play(new SafeInvoker(CustomSetMethod));
}));
```
