Installation

You need Python 3.10 or higher.

I strongly recommend to use virtual environment such as Anaconda. You can download Anaconda here.

Follow manual below to create python virtual environment for Triangler with the Anaconda.

$ conda create -n triangler python=3.12
$ activate triangler
(triangler)$ python -m pip install git+https://github.com/tdh8316/triangler/

Usage

(triangler)$ python -m triangler -h
usage: __main__.py [-h] [-o OUTPUT] [-p POINTS] [-e {CANNY,ENTROPY,SOBEL}] [-s {POISSON_DISK,THRESHOLD}] [-r {CENTROID,MEAN}] input

positional arguments:
  input                 Input image

options:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        Output image name
  -p POINTS, --points POINTS
                        Number of sample points to use
  -e {CANNY,ENTROPY,SOBEL}, --edge-detector {CANNY,ENTROPY,SOBEL}
                        Edge detection algorithm
  -s {POISSON_DISK,THRESHOLD}, --sampler {POISSON_DISK,THRESHOLD}
                        Point sampling algorithm
  -r {CENTROID,MEAN}, --renderer {CENTROID,MEAN}
                        Color polygon rendering algorithm

API

You can use Triangler as a library.

import triangler

triangler.convert(
    img="INPUT_IMAGE.jpg",
    save_path="OUTPUT_IMAGE.jpg",
)

numpy==1.22.4 scipy==1.8.1 requirements

Is your feature request related to a problem? Please describe.
Currently triangler requires numpy==1.22.4 scipy==1.8.1, or it won't run, but the systems I want to use it in require later versions of both numpy and scipy.

Describe the solution you'd like
Anyway you could adopt your functions to operate with more general or later versions?
