lpdraw 0.0.1.1

A simple python drawing package

lpdraw

This is a simple drawing package that contains Line and Circle Drawing Algorithms. This package can display the output on terminal as well as visually appealing grayscale image.

Usage

Example:

from lpdraw import Line, Circle, Clear, DisplayTerminal
from lpython import i32, Const

from numpy import empty, int32

def main():
    Width: Const[i32] = 100 # x-axis limits [0, 99]
    Height: Const[i32] = 40 # y-axis limits [0, 39]
    Screen: i32[Height, Width] = empty((Height, Width), dtype=int32)

    Clear(Height, Width, Screen)
    Line(Height, Width, Screen, 2, 4, 99, 11)
    Line(Height, Width, Screen, 0, 39, 49, 0)
    Circle(Height, Width, Screen, 52, 20, 6.0)
    DisplayTerminal(Height, Width, Screen)

main()

Output:

$ python main.py

You can also use the Display() provided in this package to generate a grascale .pgm image. You need to save the output produced on execution to a .pgm file. For example,

python main.py > img.pgm
