Bits and Bobs

This is a collection of little python hacks and workarounds that I use frequently across projects.

Install

Some dependencies that I recommend installing via conda:

conda install numpy matplotlib h5py

Our stuff:

python -m pip install git+https://github.com/pSpitzner/bitsandbobs

Then, in python:

import bitsandbobs as bnb

Why not simply pip install?

Features

Just the noteworthy ones. See each functions docstring for details.

Load and write a hdf5 files as/from nested dictionaries.

h5f = bnb.hi5.recursive_load("~/path/to/in_file.h5")
bnb.hi5.recursive_write("~/path/to/out_file.h5", h5f)

Set the size of an existing matplotlib axes element (and the padding around it). Useful when creating multi-panel figures in Affinity Designer or Inkscape.

fig, ax = plt.subplots()
bnb.plt.set_size(ax, w=3, h=2)

Convert transparent colors (r,g,b,a) to opaque equivalents (r,g,b) on a given background.

bnb.plt.alpha_to_solid_on_bg(base="red", alpha=0.5, bg="white")
