threadtone's Introduction

ThreadTone | a halftone representation of an image made of thread

The process of generating an image with thread is an idea of Petros Vrellis. As I've documented here the process is comprised of three steps:

Image pre-processing (cropping, resizing, etc.)
Algorithm to place threads
In my case parsing the result to G-Code for automated fabrication

To use this tool, run:

python threadTone.py -p [image-path] -l [number-of-lines-to-draw] -n [number-of-pins-to-draw-with]

ex: python threadTone.py -p kitten.jpg -l 2000 -n 250
ex: python threadTone.py -p puppr.png

Note: imgPath is a required field, and to give a value to numPins

A set of two example images can be found below. Please refer to my blog for more details.

threadtone's Issues

Image window appears than it crashes

I had some issues about running the code. Before I downloaded from here I coppied all lines from your project webpage: http://www.thevelop.nl/blog/2016-12-25/ThreadTone/ With somo minor modifications I succeded to run the code. However there is no display modules like you shared in project webpage. Thus I decided to download the updated version from github. When I run the code there is an image windows appears than it freezes. I tried to reduced numPines and numLines but result is still the same. Could you please help me to figure out what is the problem.

String art is way older than Petros Vrellis

String art significantly predates Petros Vrellis, who was born in 1974. For example, this page has vintage stuff from the 60's - http://vintagegoodness.com/featured-collectible-vintage-string-art-70s-craft-series-1/ - including a Star Trek kit copyright 1978.

Awesome project, BTW! It's just that Vrellis didn't create and sell his idea to a Star Trek merchandiser when he was four years old. :-)

Requirements ?

1 thing missing from the README is the requirements to use the program.

Imports. You could provide a requirements.txt for that, which'll make pip's life simple. The program could try using pip to install the requirements to the current venv automatically on start, or at least ask first.
Python version. The print(...) function can malfunction in Py2 since the grammar thinks those parenthesis are tuple indicators instead of a function. That can be fixed with from __future__ import print_function.

Update numpy int convert

Updated from

return (x.astype(np.int)-1, y.astype(np.int)-1)

return (x.astype(int)-1, y.astype(int)-1)

in line 113

The lines drawn, may not be correct

I just noticed a minor bug which draws the wrong line as the program runs.

line 200:
xLine, yLine = linePixels(coords[bestPin], coord)

I think should look like that:
xLine, yLine = linePixels(oldCoord, coords[bestPin])

Great project though, and a good excuse to finally dive a little more into numpy. Thank you for sharing.
