## Short API description
### Structs
The core of the library is the Art class, which implements the 3a structure:  
```python
class Art:
    def __init__ (self, header: Header, body: Body):
        self.header = header
        self.body = body
```
Header type contains information about the header of 3a file:  
```python
class Header:
    def __init__ (self, width: int, height: int, delay: int, loop_enable: bool, color_mod: ColorMod,
                    utf8: bool, datacols: int, preview: int, audio: str, title: str, author: str):
        self.width = width
        self.height = height
        self.delay = delay
        self.loop_enable = loop_enable
        self.color_mod = color_mod
        self.utf8 = utf8
        self.datacols = datacols
        self.preview = preview
        self.audio = audio
        self.title = title
        self.author = author
```
Body class contains a list of frames, where each frame is a list of rows, and each row is a list of row fragments:  
```python
Row = typing.List[RowFragment]

Frame = typing.List[Row]

class Body:
    def __init__ (self, frames: typing.List[Frame] ):
        self.frames = frames
```
Each RowFragment is a set of consecutive symbols with the same values of foreground and background colors:  
```python
class RowFragment:
    def __init__ (self, text: str, fg_color: Color, bg_color: Color):
        self.text = text
        self.fg_color = fg_color
        self.bg_color = bg_color
```
### Methods
`Art.load` and `art.save` methods allow you to convert strings to `Art` and back.  
`Art.load_file` and `art.save_file` methods allow you to read 3a files to `Art` and write `Art` to 3a files.
