OpenPIV consists in a Python and Cython modules for scripting and executing the analysis of 
a set of PIV image pairs. In addition, a Qt and Tk graphical user interfaces are in 
development, to ease the use for those users who don't have python skills.

## Warning

The OpenPIV python version is still in its *beta* state. This means that
it still might have some bugs and the API may change. However, testing and contributing
is very welcome, especially if you can contribute with new algorithms and features.


## Test it without installation
Click the link - thanks to BinderHub, Jupyter and Conda you can now get it in your browser with zero installation:

## Installing

### Recommended: Using uv (fastest)

[uv](https://github.com/astral-sh/uv) is a fast Python package installer and resolver written in Rust:

    pip install uv
    uv pip install openpiv

### Using pip (standard)

Use PyPI: <https://pypi.python.org/pypi/OpenPIV>:

    pip install openpiv

### Or [Poetry](https://python-poetry.org/)

    poetry add openpiv

### Note on Conda/Anaconda

⚠️ **Conda packages are no longer actively maintained.** The conda-forge package may be outdated.

If you previously installed OpenPIV via conda, you can migrate to pip or uv:

    # Remove the conda package
    conda remove openpiv
    
    # Install with pip or uv
    pip install openpiv
    # or
    uv pip install openpiv
    
    
### To build from source

<!-- TODO: Change this build method to use poetry -->

Download the package from the Github: https://github.com/OpenPIV/openpiv-python/archive/master.zip
or clone using git

    git clone https://github.com/OpenPIV/openpiv-python.git

Using distutils create a local (in the same directory) compilation of the Cython files:

    python setup.py build_ext --inplace

Or for the global installation, use:

    python setup.py install
