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 this workflow from code
Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.
Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
// 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");The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).
Comfy Cloud API access requires a plan with an API key.
