This workflow upscales raster illustrations while preserving smooth color regions and clean linework using a Topaz-based enhancement pass. It starts by loading your source image with LoadImage and reading its original dimensions via GetImageSize. A PrimitiveNode controls the scale multiplier (for example, 2x or 4x). ImageScaleBy resizes the image to the target resolution, ensuring predictable output size. The upscaled image is then refined by TopazImageEnhanceV2, which applies learned enhancement tuned for illustrations to smooth gradients, reduce artifacts, and crisp up edges while aiming to preserve color accuracy.
For review and output, ImageCompare (available under Nodes 2.0) places the original and enhanced versions side-by-side so you can quickly judge improvements and spot any artifacts that may appear at aggressive scales. Finally, SaveImage writes the enhanced result to disk. The included MarkdownNote provides inline guidance, and the example input (silent_sanctuary.jpg) helps you test settings before applying the process to your own art. This workflow is practical when you need high-resolution, print- or delivery-ready illustrations from small web images with minimal manual cleanup.
API
Use este workflow a partir do código
Todo workflow Comfy é um grafo JSON. O payload abaixo é este workflow, exatamente como o ComfyUI executa — obtenha-o pela URL, mantenha-o no controle de versão ou carregue-o no ComfyUI e execute nó por nó.
Execute a partir de TypeScript ou Python com o Comfy SDK. O mesmo código serve para o Comfy Cloud ou um ComfyUI hospedado por você — apenas a URL base muda.
// 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");O SDK utiliza um workflow no formato API: abra este workflow no ComfyUI e use Arquivo → Exportar Workflow (API).
O acesso à API do Comfy Cloud requer um plano com chave de API.
