PyPendentDrop

Open-source Python API with a graphical and command-line interface to measure surface tension coefficients from images of pendent drops.

• Package on PyPI
• Documentation on ReadTheDocs
• Source code on GitHub

Installation

Simply use

pip install pypendentdrop[full]

or, if you only want to use the command-line version (resp. the graphical version), you can replace [full] by [cli] (resp. [gui]). Use no option to download a minimal working version of the library.

Using PyPendentDrop

Graphical interface

To launch the gui version, use the command

ppt-gui

Use the relevant fields to provide an image, the pixel density of your image and the relevant physical parameters (density contrast, acceleration of gravity). Buttons allow you to estimate the parameters coarsely and to optimize this estimation. You can manually change and/or fix the values of the parameters.

Command-line

To use the command-line version, use

ppt-cli

Use the -h (help) option to list the availables options and the -v (verbose) option to display more information as the program goes.

In a python script

In the import section of your script, write

import pypendentdrop as ppd

and you can then use the functions defined in the library. An example script examplescript.py is provided on the GitHub repository.
