## 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.

```
<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/images/7.png">	

### Basic
```pycon
>>> import random
>>> import math
>>> 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()
```
<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/images/1.png">	

### 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`, `MOLLWEIDE` and `RANDOM`
* Default projection is `RECTILINEAR`

### Range
```pycon
>>> g = GenerativeImage(f1, f2)
>>> g.generate(start=-2*math.pi, step=0.01, stop=0)
>>> g.plot()
>>> g.seed
234752
>>> plt.show()
```
<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/images/3.png">	

### 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 supported formats:

    1. Color name (example: `color="yellow"`)
    2. RGB/RGBA (example: `color=(0.1,0.1,0.1)`, `color=(0.1,0.1,0.1,0.1)`)
    3. Hex (example: `color="#eeefff"`)
    4. Random (example: `color="random"`)
    5. Complement (example: `color="complement", bgcolor="blue"`)
    6. Transparent (example: `bgcolor="transparent"`)
    7. List (example: `color=["black", "#fffeef",...]`)

⚠️ **Transparent** mode is only available for background
⚠️ **List** mode is only available for color
⚠️ In **List** mode, the length of this list must be equal to the lengths of data1 and data2.

#### Point Color
```pycon
>>> colorarray = [
...  [0.7, 0.2, 0.2, 1],
...  [0.6, 0.3, 0.2, 1],
...  "black",
...  [0.4, 0.4, 0.3, 1],
...  [0.3, 0.4, 0.4, 1],
...  "#ff2561"]
>>> g.generate()
>>> g.seed
454893
>>> g.plot(cmap=colorarray, color=g.data2, projection=Projection.POLAR)
>>> plt.show()
```
<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/images/8.png">	

You can make your custom color map and use it in Samila.

### Regeneration
```pycon
>>> g = GenerativeImage(f1, f2)
>>> g.generate(seed=1018273)
>>> g.plot(projection=Projection.POLAR)
>>> plt.show()
```
<img src="https://github.com/sepandhaghighi/samila/raw/master/otherfiles/images/5.png">	

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

```pycon
>>> g.nft_storage(api_key="YOUR_API_KEY")
{'status': True, 'message': 'FILE_LINK'}
```

### Save image
Save generated image

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

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

### Save data
Save generated image data

```pycon
>>> g.save_data(file_adr="data.json")
{'status': True, 'message': 'FILE_PATH'}
```
So you can load it into a `GenerativeImage` instance later by

```pycon
>>> g = GenerativeImage(data=open('data.json', 'r'))
```

Data structure:
```JSON
{
  "plot": {
    "projection": "polar",
    "bgcolor": "black",
    "color": "snow",
    "spot_size": 0.01
  },
  "matplotlib_version": "3.0.3",
  "data1": [
    0.3886741692042526,
    22.57390286376703,
    -0.1646310981668766,
    66.23632344600155
  ],
  "data2": [
    -0.14588750183600108,
    20.197945942677833,
    0.5485453260942901,
    -589.3284610518896
  ]
}
```

### Save config
Save generated image config. It contains string formats of functions which is also human readable.

```pycon
>>> g.save_config(file_adr="config.json")
{'status': True, 'message': 'FILE_PATH'}
```
So you can load it into a `GenerativeImage` instance later by

```pycon
>>> g = GenerativeImage(config=open('config.json', 'r'))
```

Config structure:

```JSON
{
    "matplotlib_version": "3.0.3",
    "generate": {
        "seed": 379184,
        "stop": 3.141592653589793,
        "step": 0.01,
        "start": -3.141592653589793
    },
    "f2": "random.uniform(-1,1)*math.cos(x*(y**3))+random.uniform(-1,1)*math.ceil(y-x)",
    "f1": "random.uniform(-1,1)*math.ceil(y)-random.uniform(-1,1)*y**2+random.uniform(-1,1)*abs(y-x)",
    "plot": {
        "color": "snow",
        "bgcolor": "black",
        "projection": "polar",
        "spot_size": 0.01
    }
}
```

## 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)
```
