## Overview

<p align="justify">	
Samila is a generative art generator written in Python, Samila let's you create arts based on many thousand points. The position of every single point is calculated by a formula, which has random parameters. Because of the random numbers, every image looks different.

## Usage

### Basic
```pycon
>>> import random
>>> import math
>>> import matplotlib.pyplot as plt
>>> from samila import GenerativeImage
>>> def f1(x,y):
    result = random.uniform(-1,1) * x**2  - math.sin(y**2) + abs(y-x)
    return result
>>> def f2(x,y):
    result = random.uniform(-1,1) * y**3 - math.cos(x**2) + 2*x
    return result
>>> g = GenerativeImage(f1,f2)
>>> g.generate()
>>> g.plot()
>>> g.seed
188781
>>> plt.show()
```

### Projection
```pycon
>>> from samila import Projection
>>> g = GenerativeImage(f1,f2)
>>> g.generate()
>>> g.plot(projection=Projection.POLAR)
>>> g.seed
829730
>>> plt.show()
```
<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/images/2.png">	

* Supported projections : `RECTILINEAR`, `POLAR`, `AITOFF`, `HAMMER`, `LAMBERT` and `MOLLWEIDE`
* Default projection is `RECTILINEAR`

### Range
```pycon
>>> g = GenerativeImage(f1,f2)
>>> g.generate(start = -2*math.pi,step=0.1,stop=0)
>>> g.plot()
>>> g.seed
234752
>>> plt.show()
```

### Color
```pycon
>>> g = GenerativeImage(f1,f2)
>>> g.generate()
>>> g.plot(color="yellow",bgcolor="black",projection=Projection.POLAR)
>>> g.seed
1018273
>>> plt.show()
```
<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/images/4.png">	

* Supported colors are available in `VALID_COLORS` list
* `color` and `bgcolor` parameters support color name and RGB/RGBA formats

### Regeneration
```pycon
>>> g = GenerativeImage(f1,f2)
>>> g.generate(seed=1018273)
>>> g.plot(projection=Projection.POLAR)
>>> plt.show()
```

### NFT.storage
Upload generated image directly to [NFT.storage](https://NFT.storage)

```pycon
>>> g.nft_storage(api_key = YOUR_API_KEY)
{'status': True, 'message': 'Everything seems good'}
```

### Save
Save generated image

```pycon
>>> g.save_image(file_adr="test.png")
{'status': True, 'message': 'Everything seems good'}
```
Save generated image in higher resolutions

```pycon
>>> g.save_image(file_adr="test.png", depth=5)
{'status': True, 'message': 'Everything seems good'}
```

## Mathematical details
Samila is simply a transformation between a square-shaped space from the Cartesian coordinate system to any arbitrary coordination like [Polar coordinate system](https://en.wikipedia.org/wiki/Polar_coordinate_system).

### Example
<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/mathematical_details/transformation.png">

We have set of points in the first space (left square) which can be define as follow:

<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/mathematical_details/S1.jpg">

And bellow functions are used for transformation:

```pycon
>>> def f1(x,y):
    result = random.uniform(-1,1) * x**2  - math.sin(y**2) + abs(y-x)
    return result
>>> def f2(x,y):
    result = random.uniform(-1,1) * y**3 - math.cos(x**2) + 2*x
    return result
```

<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/mathematical_details/S2.jpg">

here we uses `Projection.POLAR` so later space will be the polar space and we have:

```pycon
>>> g = GenerativeImage(f1,f2)
>>> g.generate(seed=10)
>>> g.plot(projection=Projection.POLAR)
```
