# Building
Build and install wheel, provided you are in a virtual environment:
git submodule update --init --recursive
python -m pip install -r requirements-build.txt
python setup.py bdist_wheel
pip install dist/blosc2_openhtj2k-*.whl
# J2K wheel
By following the next steps you can edit J2K sources and work with the plugin in C-Blosc2.
## Configuring J2K params
In `blosc2_htj2k.cpp` you can change the default parameters as you want.
Moreover, in encoder you can use the `j2k_params` as C-Blosc2 `cparams.codec_params` to choose J2K parameters.
## Create the wheel
Once you have J2K parameters set, you have to create a wheel with the compressor inside:
```shell
python setup.py bdist_wheel
```
## Verify the wheel is working
```shell
pip install dist/blosc2_openhtj2k-*.whl
```
And then simulate that you are going to uninstall. You will be presented where the plugin has been installed:
```shell
pip uninstall blosc2_openhtj2k
```
For example, the shared library should appear somewhere like:
```shell
ls -l /Users/faltet/miniconda3/lib/python3.9/site-packages/blosc2_openhtj2k
total 112
-rw-r--r-- 1 faltet staff 258B Mar 6 13:45 __init__.py
drwxr-xr-x 3 faltet staff 96B Mar 6 13:45 __pycache__/
-rwxr-xr-x 1 faltet staff 48K Mar 6 13:45 libblosc2_plugin_example.so*
```
In the future, you should be able to test that the wheel is working with this command:
```shell
blosc2_test_plugin plugin_example_name
```
## Work in C-Blosc2
Now that you have the wheel installed, work with it in C-Blosc2.
That's all folks!
