Building and installing the package
Make sure you have the latest version of setuptools, pip and venv packages as the building requires some
newer features of setuptools.

The command should build a wheel file inside the dist folder. To install it run:
pip install <PATH TO WHEEL FILE>
Usage
Open empty window
It is possible to run the viewer without any data.
from primawera.app import create_window
create_window()
Visualise numpy data
If you want to visualise data inside a numpy array, you will have to import the function run_app. Sometimes it is not
possible to automatically infer the mode (see Pillow image modes).
in which case it has to be provided manually.
from primawera.app import run_app
import numpy as np
data = np.random.random((10, 10, 10))
run_app(data)
# Or
run_app(data, mode="float")
# You can also add overlay data
overlay_data = np.random.random(data.shape) # same shape as data
run_app(data, mode="float", overlay_data=overlay_data)
Run from terminal
Simply run
primawera
