Hydra OS mark
hydra-mark.png is the original transparent image generated with the built-in
imagegen tool. The complete prompt and conversion settings are in
generation.json. preview.png shows the resulting ASCII
glyphs; the shipped asset is image/rootfs/usr/share/hydra/fastfetch.txt.
The 44-column mark uses ordinary ASCII characters, cyan Fastfetch color $1,
and a white $2 caption. Pillow is needed only to regenerate the text, not to
run Fastfetch or build an image with the checked-in asset.
From the repository root, with Python and Pillow available:
python3 dev/render-logo.py
fastfetch --config image/rootfs/etc/fastfetch/config.jsonc \
--logo image/rootfs/usr/share/hydra/fastfetch.txt --pipe false
On a Nix development host, the converter can also run in a temporary environment:
nix-shell -p 'python3.withPackages (p: [p.pillow])' \
--run 'python3 dev/render-logo.py'
The converter uses opacity to preserve the single-color silhouette, removes faint alpha noise, and accounts for terminal character proportions. It preserves the PNG source. Future ISO builds and runtime update bundles include the new text; previously built ISOs and installed guests retain their existing logo.
