True-Color Terminal Image visualization library for Python

A tool to view images or matrices directly in your (true-color supporting) terminal. Great for debugging purposes!

It can visualize (imprint) or convert to an image representation (imgify) anything that

• can be cast into a float- or int- numpy array using numpy.array and
• has 2 dimensions (grayscale) or
• has 3 dimensions where the 1, 3 or 4 color channels (grayscale/ RGB/ RGBA) come first or last.

Install using pip

$ pip install 'git+git://github.com/chr5tphr/tctim'

Usage

Example in Python:

import numpy as np
from tctim import imprint

# make some data to visualize
grid = np.mgrid[:32, :32]
dist = ((np.array([15.5, 15.5])[:, None, None] - grid) ** 2).sum(axis=0) ** .5

# print to console
imprint(dist)

# make some colorful data
col = np.stack([np.zeros_like(dist), dist, -dist], axis=-1)
imprint(col)

# ================================
# save file to visualize externally or read later with CLI
from PIL import Image
from tctim import imgify

uint8_array = imgify(col)
image = Image.fromarray(uint8_array)
image.save('someimage.png')

A command-line interface is included:

$ tctim someimage.png
