# Recipe gallery

24 small standalone `.ips` patterns for the v0.4 language. Each draws a
32×32 asset, uses only the existing runtime instructions, and can be copied
or combined with the other recipes. The variant badge demonstrates `v`/`a`;
the uniform emblem exposes color, scale and density inputs. The attachment
recipe writes structured point outputs alongside its pixels.

The stored sources use the compiler's canonical style. The 0.5 formatter's
`--format-only` output is idempotent and preserves their exact stripped bytecode;
the recipes also compile with the frozen 0.4 compiler. Comments remain in the
canonical source. Check the gallery with:

```sh
python3 scripts/check_recipe_format.py build/tools/ipc
```

```sh
build/tools/ipc examples/recipes/09-rounded-mask.ips --strip -o /tmp/rounded.iprop
build/tools/ipgen /tmp/rounded.iprop --seed 7 -o /tmp/rounded.png
```

Alpha examples start from an opaque background because the frozen pixel
compositor preserves the destination alpha for translucent source colors.
For imported part composition, see `../portrait.ips` and `../plant.ips`.
