luxconnector 0.1.1

This is a python wrapper around the Lux Client windows solution

luxconnector

This is a python wrapper for the Lux Client windows solution. The package will only work on Windows.

Installation

To install this package follow the these steps:

Step 1: Divers

Make sure you have or had a CytoSmart application installed. This is needed to have all the correct drivers installed. It doesn't matter if the app is uninstalled afterwards.

Step 2: pip install

pip install luxconnector

Usage

Make sure the lux is physically connected to your computer via a USB3 port. The luxconnector is an object that maintains the connection with the Lux. To create the object use the following code:

from luxconnector import LuxConnector
connector = LuxConnector()

Getting a single image

When you want a single image taken at this moment use get_image. This will return the image as a numpy array.

img = connector.get_image()

Changing the focus

This function will change the focus for the luxconnector object. Every image taken after this function will have the new focus.

The focus is in the range 0 until 1. (0.0 and 1.0 are valid entries)

connector.set_focus(0.5)
img1 = connector.get_image() # Image with focus of 0.5
connector.set_focus(0.7)
img2 = connector.get_image() # Image with focus of 0.7
img3 = connector.get_image() # Image with focus of 0.7

Getting a z-stack

This function will return a list of numpy arrays. Each image will be at a different focus level.

This code will create a z-stack of 6 images. The focuses of these images will be [0.5, 0.6, 0.7, 0.8, 0.9, 1.0]

list_of_imgs = connector.get_z_stack(num_img = 6, start_focus = 0.5, stop_focus = 1)

Changing zoom modes

There are 2 zoom modes: "IN" and "OUT". While zoomed in the resolution is higher but the ROI is smaller, zoomed out has a higher ROI but a lower resolution.

Changing this will change it for every image or z-stack taken afterwards.

connector.set_zoom("IN")
img1 = connector.get_image() # Image is zoomed in
connector.set_zoom("OUT")
img2 = connector.get_image() # Image is zoomed out

Live view

The live view of the Lux is hosted at http://localhost:3333/luxservice/live. This image can only been seen if the live view is turned on (by default the live view is turned on).

connector.set_liveview(True) # in the browser you can see the image being updated
connector.set_liveview(False) # Led of Lux turns off till you take a picture
