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
