Collection of C extension modules for SUPer with pure-python fallbacks

• Brule: Bitmap RUn LEngth coder and decoder.
• LayoutEngine: An optimal two-rects layout finder for a sequence of images.

Brule implements 3 times the same run-length encoder and decoder.

• C (fastest)
• numba (fast)
• pure Python (slow)

For the encoder, the C implementation is up to 20 times faster than numba. The pure Python implementation does not compete and is only there for convenience.

$ python -m pip install brule

The run-length codec is operated like this:

>>> from brule import Brule
>>> import numpy as np
>>> bitmap_orig = np.ones((1080, 1920), np.uint8)
>>> rle_data = Brule.encode(bitmap_orig)
>>> bitmap = Brule.decode(rle_data)
>>> assert np.all(bitmap == bitmap_orig)
True
