### Basic Tweening Function Examples

Source: https://pypi.org/project/pytweening/1.2.0

Demonstrates the output of several tweening functions with different input values. These functions take a float between 0.0 and 1.0 representing the progress of the tween.

```python
>>> pytweening.linear(0.5)
0.5
>>> pytweening.linear(0.75)
0.75
>>> pytweening.linear(1.0)
1.0
>>> pytweening.easeInQuad(0.5)
0.25
>>> pytweening.easeInQuad(0.75)
0.5625
>>> pytweening.easeInQuad(1.0)
1.0
>>> pytweening.easeInOutSine(0.75)
0.8535533905932737
>>> pytweening.easeInOutSine(1.0)
1.0
```

### Interpolated Point on a Line

Source: https://pypi.org/project/pytweening/1.2.0

Calculates an interpolated point on a line defined by two endpoints, based on a progress factor (0.0 to 1.0). This function can find points before the start or after the end of the defined segment.

```python
>>> getLinePoint(0, 0, 5, 10, 0.0)
(0.0, 0.0)
>>> getLinePoint(0, 0, 5, 10, 0.25)
(1.25, 2.5)
>>> getLinePoint(0, 0, 5, 10, 0.5)
(2.5, 5.0)
>>> getLinePoint(0, 0, 5, 10, 0.75)
(3.75, 7.5)
>>> getLinePoint(0, 0, 5, 10, 1.0)
(5.0, 10.0)
```

### Bresenham Line Algorithm

Source: https://pypi.org/project/pytweening/1.2.0

Provides an implementation of the Bresenham line algorithm to generate a list of (x, y) coordinates for a line between two points.

```python
>>> pytweening.getLine(0, 0, 5, 10)
[(0, 0), (0, 1), (1, 2), (1, 3), (2, 4), (2, 5), (3, 6), (3, 7), (4, 8), (4, 9), (5, 10)]
```

### Iterating XY Coordinates with Ease-Out Quadratic Interpolation

Source: https://pypi.org/project/pytweening/1.2.0

Uses an iterator to generate XY coordinates along a line with ease-out quadratic interpolation. The step parameter controls the increment for each iteration, and floating-point rounding errors may occur.

```python
>>> for x, y in pytweening.iterEaseOutQuad(0, 0, 100, 150, 0.1): print(x, y)
...
0.0 0.0
19.0 28.5
36.00000000000001 54.00000000000001
51.0 76.5
64.00000000000001 96.00000000000001
75.0 112.5
84.0 126.0
90.99999999999999 136.5
96.00000000000001 144.0
99.0 148.5
100.0 150.0
```

### Iterating XY Coordinates with Linear Interpolation

Source: https://pypi.org/project/pytweening/1.2.0

Uses an iterator to generate XY coordinates along a line with linear interpolation. The step parameter controls the increment for each iteration.

```python
>>> import pytweening
>>> for x, y in pytweening.iterLinear(0, 0, 100, 150, 0.1): print(x, y)
...
0.0 0.0
10.0 15.0
20.0 30.0
30.000000000000004 45.00000000000001
40.0 60.0
50.0 75.0
60.0 90.0
70.0 105.0
80.0 119.99999999999999
89.99999999999999 135.0
100.0 150.0
