keryx portrait¶

Stylise reference photo(s) into the risograph avatar via the image provider (Gemini image-to-image) — a port of gen-portrait.py. Resolves a portrait theme for the prompt.

keryx portrait --ref photo1.jpg [--ref photo2.jpg ...] [--theme <kw>] [--n N] [--out portrait]

Flag	Meaning	Default
`--ref`	a reference photo (repeatable)	— (≥1 required)
`--theme`	portrait theme (the avatar prompt)	configured portrait default
`--n`	number of variants	1
`--out`	output path prefix → `<out>-<i>.png`	`portrait`

Credential: GEMINI_API_KEY (env). Used for the blog logo / social avatar, not the per-post pipeline. Reference photos are sent as image-to-image conditioning; their MIME type is detected from content.

keryx portrait --ref me1.jpg --ref me2.jpg --n 3

Provider-selected via providers.image — see Providers.
