TermGFX
A yet another terminal graphics library written in Python.
Why tho?
The idea behind this project is to allow simple yet extensible graphics processing in the terminal. I'm a videogames enjoyer and I have used libraries such as PyGame, so it was an inspiration for me to write my own graphics lib. I decided to use a terminal/TTY as canvas, because I spend a lot of time sitting at it as a Linux user. Moreover, it felt like something a bit more unique (even though there were a bunch of such project already, shh)
What it can
Draw
- Dots
- Lines
- Colors
What's planned
- Cirle shapes
- Arbitrary shapes (with straight sides)
Installation
Prerequisites
In order to use the package, you need Python 3
- Python (3.6+)* (Some examples use 3.10, though)
* If incorrect, please report (too lazy to figure out actual range of versions needed)
pip
You can use pip
or pip3
to install TermGFX by executing
pip --user install termgfx
Note: you can omit --user
, but it's not recommended (see [why][https://stackoverflow.com/questions/42988977/what-is-the-purpose-of-pip-install-user])
From source
The source code is located in <project root>/src/TermGFX/
, so, in order to use it, you might just copy the file onto yout project directory, though it's not recommended (pip
is a better option)
Usage
To get more information on project usage, you can view examples located in <project root>/examples/
Here's an overview:
First, import the Canvas
from TermGFX.engine import Canvas
Then, create a Canvas
instance
window_size = (20, 10) # Size of the canvas
canvas = Canvas(window_size) # Instantiate a canvas with the size of (20, 10)
Pixels
Now you can set "pixels" on the canvas
char = "O" # A character to be displayed
canvas.set((0, 0), char) # Set (0, 0) pixel to "O"
And draw the canvas on the "screen"
canvas.draw()
Shapes
For all shapes, see shapes.py
Example: Drawing a rectangle filled with "$" chars:
from TermGFX.engine import Canvas
from TermGFX.shapes import FilledRect
canvas = Canvas((20, 10))
rect = FilledRect((5, 2), "$")
rect.draw(canvas)
canvas.draw()
Tip: shapes usually have a draw(surface: engine.Canvas)
method that allows for easy drawing on a surface
