# fpzip
|
||||
|
||||
fpzip is a compression algorithm supporting lossless and lossy encoding for up to 4 dimensional floating point data. This package contains Python C++ bindings for the fpzip algorithm (version 1.3.0). The version number for this package is independent. Python 3.7+ is supported.
|
||||
|
||||
```python
|
||||
import fpzip
|
||||
import numpy as np
|
||||
|
||||
data = np.array(..., dtype=np.float32) # up to 4d float or double array
|
||||
# Compress data losslessly, interpreting the underlying buffer in C (default) or F order.
|
||||
compressed_bytes = fpzip.compress(data, precision=0, order='C') # returns byte string
|
||||
# Back to 3d or 4d float or double array, decode as C (default) or F order.
|
||||
data_again = fpzip.decompress(compressed_bytes, order='C')
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
#### `pip` Binary Installation
|
||||
|
||||
```bash
|
||||
pip install fpzip
|
||||
```
|
||||
|
||||
If we have a precompiled binary available the above command should just work. However, if you have to compile from sounce, it's unfortunately necessary to install numpy first because of a quirk in the Python installation procedure that won't easily recognize when a numpy installation completes in the same process. There are some hacks, but I haven't gotten them to work.
|
||||
|
||||
#### `pip` Source Installation
|
||||
|
||||
*Requires C++ compiler.*
|
||||
|
||||
```bash
|
||||
pip install numpy
|
||||
pip install fpzip
|
||||
```
|
||||
|
||||
#### Direct Installation
|
||||
|
||||
*Requires C++ compiler.*
|
||||
|
||||
```bash
|
||||
$ pip install numpy
|
||||
$ python setup.py develop
|
||||
```
