连环画分页浏览

This one is the minimal utility of the comic set, and it does exactly one job: pull a single page out of a comic image batch so you can look at it with a plain Preview Image node. 连环画分页浏览 ("page-by-page browsing") is the cheap preview loop - bump a number, see one page, repeat - before you bother exporting a full HTML viewer.

How it works

It takes the IMAGE batch from DoubaoComicBookNode.comic_images, slices out one frame by page_index, and returns it as a single-image IMAGE tensor. page_index is 1-based (page 1 = first panel). The loop toggle is the fun part: with loop on (the default), page 5 on a 3-page comic wraps to page 2 instead of erroring - handy for cycling through panels indefinitely. With loop off it just clamps to the first or last page. The slice is forced into contiguous memory, which avoids weird view-slicing glitches that some upstream nodes can introduce.

Nothing about it is fancy, and that's the point. It's local, instant, and free - no API calls, no key, no generation cost. Perfect for checking whether a specific scene came out right without downloading the whole batch.

Inputs and outputs

• images (required) - the comic IMAGE batch.
• page_index - 1-based page number (1–9999), default 1.
• loop - wrap out-of-range pages (default true).

Outputs are page_image (that single page as an IMAGE - wire it straight into a Preview Image node) and page_info (a string like "第 2/6 页" telling you which page you're looking at, useful if you're logging or chaining it into a text display).

Install & setup

Same pack as the rest of the comic tools:

cd ComfyUI/custom_nodes
git clone https://github.com/xuchenxu168/ComfyUI_doubao_seed
cd ComfyUI_doubao_seed
pip install -r requirements.txt

Restart ComfyUI and it appears under Ken-Chen/Doubao.

Gotchas

The honest limit: it's page selection, not a real reader. To actually flip through panels you'll bump page_index and re-queue, which is fine for spot-checking and tedious for reading a whole story. If you find yourself scrolling through a 12-page comic this way, that's the moment to wire up ComicHTMLViewerNode + the embedded preview instead - same source batch, a real book experience, and it doesn't cost anything extra to build. There's no text preview here either; if you want to see narration next to a page, the HTML viewer is the tool.
