Everything here was produced by this toolkit and is committed so the README can show real output rather than describe it. Regenerate any of it with the commands below; nothing is hand-edited beyond downscaling for the repository.
openair-max-*.jpg are derived from the Open Air Max demo project by
AirGradient, which ships with KiCad in
/usr/share/kicad/demos/openair-max and is licensed
CC BY-SA 4.0. These rendered
images are adaptations of that work and are therefore also CC BY-SA 4.0 —
unlike the rest of this repository, which is Apache-2.0.

diff-schematic.jpg and diff-board.jpg are eda diff run over two revisions of
the test fixture, with C2 moved on the sheet, R1 moved on the board and its value
changed from 10k to 4k7. Red is what the old revision had and the new one does
not; green is the other way round, so a part that moved is both. Both are the
zoomed detail crop the command writes alongside the full page — on an A4 sheet the
change is a few hundred pixels of two megapixels.

Both come from this repository’s own fixture, so they are Apache-2.0 like the rest of it.
rc-lowpass-*.jpg come from tests/fixtures/spice/rc_lowpass.cir,
which is part of this repository (Apache-2.0). Its corner frequency is
1/(2πRC) = 1000 Hz by construction, which is what the test-suite checks against.
