📷 Passport Tile (4x6)

Passport Tile (4x6) is the last node in the passport pipeline of the comfyui-auto-anime-prompts pack, and it's the one that saves you from opening GIMP. It takes a single square passport photo and tiles it four times onto a standard 4×6-inch print sheet at 300 DPI - 1800×1200 pixels - so you can save one image and order a single 4×6 print from any photo kiosk.

It's the print-shop trick automated: passport services charge a premium for a sheet that's four copies of the same photo, and the machine that makes them isn't magic. The node is the machine.

How it works

From nodes/passport_photo.py, it's a short, deterministic routine:

1. Take your image (ideally the 600×600 output of Passport Resize); if it isn't 600×600 it gets resized to that first.
2. Create a white 1800×1200 canvas (4×6 inches at 300 DPI).
3. Paste the photo at four positions: a 2×2 grid, centered horizontally with a 300px margin on each side.

Output: one tiled_image, ready to save and print.

There's exactly one input - image - and no settings to misconfigure, which is honestly the best feature a node like this can have. The layout is hard-coded the way kiosk layouts are: 2 across, 2 down, no fuss.

The gotcha, same as its sibling

Like Passport Resize, this node processes only image[0] - the first frame of the batch. It doesn't tile four different photos onto one sheet (a real need if you're printing four different people); it tiles the same photo four times. If you want a mixed sheet, you'd have to build it yourself. That limitation is exactly what the 2×2-of-one-photo use case expects, so it's rarely a problem - just don't assume a batch of four becomes a family sheet.

Install

Standard for the pack:

cd ComfyUI/custom_nodes
git clone https://github.com/jluo-github/comfyui-auto-anime-prompts

Then restart ComfyUI, or use Manager and search "Auto Anime Prompt". No extra Python dependencies (Pillow/numpy/torch are already in ComfyUI), no model downloads, MIT licensed. This node works standalone on any square-ish image - it doesn't need the Qwen editing half of the pipeline at all.

Full pipeline, for context

The intended flow, one node after another: Passport Prompt writes the edit instruction → Qwen-Image-Edit executes it → Passport Resize enforces the 2×2 spec → Passport Tile builds the printable sheet. Each node is small and honest about its single job. That's a nice bit of design for a pack that's otherwise all anime tags - and the tile node is the one you can reach for even if you never touch the rest.
