This ComfyUI tutorial workflow shows you how to cleanly upscale a single image using Bria’s dedicated resolution enhancement API. The core BriaIncreaseResolution node takes an input from LoadImage, sends it to the Bria API, and returns a higher-resolution version that preserves the original content without inventing new details or regenerating the scene. It supports JPEG and PNG inputs in RGB, RGBA, or CMYK color modes, and enforces a maximum area of 8192×8192 pixels to keep processing fast and reliable. Built-in content moderation checks both the input and the enhanced output for policy compliance before finalizing results.
Technically, the graph is straightforward and focused: LoadImage feeds your source into BriaIncreaseResolution, where you specify your target dimensions or scale within the allowed limits. ImageCompare then places the original and the upscaled image side-by-side so you can evaluate edge fidelity, text clarity, and fine textures at a glance. Finally, SaveImageAdvanced writes the enhanced output with your preferred filename, folder, and format (PNG for lossless graphics and text, JPEG for smaller photo files), making it a practical tool for print prep, large digital displays, and professional design workflows that need reliable resolution increases without stylistic changes.
API
從程式碼使用此工作流
每個 Comfy 工作流都是一個 JSON 圖。下方的 payload 就是此工作流，與 ComfyUI 執行時完全相同 — 你可以從此 URL 取得、放入版本控制，或在 ComfyUI 載入並逐節點執行。
使用 Comfy SDK 以 TypeScript 或 Python 執行。相同程式碼可用於 Comfy Cloud 或你自架的 ComfyUI — 只需更改 base URL。
// Install (beta)
npm i @comfyorg/sdk
// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");SDK 需使用 API 格式的工作流：請在 ComfyUI 開啟此工作流，並使用 檔案 → 匯出工作流（API）。
