Title Card Image

Render a static title / ending card PNG with Pillow. Centered headline + optional subtitle on a solid-colour background. Uses managed or platform CJK fonts with glyph verification and fails actionably instead of rendering tofu. Pure deterministic, no LLM, no network. Used by meta-short-drama for opening and closing cards.

title-card-image

Renders a centered-text PNG suitable for a cover / ending card before animating into a clip with video-still-animator.

Inputs (`with:`)

key	required	default	notes
`text`	yes	—	Headline text. Auto-wraps at ~10 chars per line for CJK.
`output`	yes	—	Output `.png` path.
`subtitle`	no	`""`	Smaller line beneath the headline.
`background`	no	`#101018`	Hex color `#RRGGBB`.
`text_color`	no	`#ffffff`	Headline color.
`font_size`	no	`96`	Headline font size in pixels.
`subtitle_size`	no	`36`	Subtitle font size in pixels.
`width`	no	`720`	Output width in pixels. Match the merge pipeline.
`height`	no	`1280`	Output height. 720x1280 = 9:16.
`font`	no	`""`	Optional `.ttf`, `.otf`, or `.ttc` path. Must contain the requested CJK glyphs.

Output

Prints the absolute path of the written PNG on stdout. The PNG is RGB (no alpha), JPEG-quality-equivalent file ~30-80 KB depending on text length.

Font fallback

Resolution order is --font, the managed media directory from OPENSQUILLA_MEDIA_FONTS_DIR, user font directories, then platform defaults: Microsoft YaHei / SimHei / DengXian on Windows; PingFang / Hiragino Sans GB / STHeiti / Songti on macOS; Noto CJK / Source Han / WenQuanYi on Linux. Font collection files (.ttc/.otc) are supported. Before drawing, the renderer compares requested non-ASCII glyphs with the font's missing-glyph signature. A font that would produce tofu is skipped. If no compatible scalable font exists, the step fails with an actionable --font / OPENSQUILLA_MEDIA_FONTS_DIR message for CJK or other non-ASCII text; it never silently emits tiny bitmap squares. Pure ASCII cards remain available on minimal systems through Pillow's built-in font when no scalable font is installed.

Limits

No alpha / transparency.
No rich text styling (italic / drop-shadow / gradient). For richer cards, generate a real image via nano-banana-pro instead.
Headline wrap is character-count-based for CJK and whitespace-based for ASCII; mixed strings break at the CJK character count.
