              "## FLUX Erase Image (BFL API)\n\nRemoves whatever you mask and reconstructs the background behind it. No prompt is required — only an image and a binary mask.\n\n---\n\n### Quick start in this graph\n\n1. **Load Image** — Click the widget, upload your photo (min **256×256**). The same node outputs **IMAGE** and **MASK**.\n2. **Paint the mask** — On **Load Image**, open the mask editor (right‑click the node → [mask editor](https://docs.comfy.org/interface/maskeditor)). Paint over everything you want removed (people, text, cables, logos, shadows you want gone).\n   - Alternative: use a separate black/white mask via **Load Image (as Mask)**, then wire that into **Flux Erase Image**.\n   - Convention matches the API: **white = erase**, **black = keep**. Mask is auto-resized to match the image.\n3. **Flux Erase Image** — `dilate_pixels` (default **10**, range **0–25**) expands the mask slightly so edges, hair, and soft boundaries are fully covered. Increase to **15–20** for fuzzy edges; lower if you are erasing near important detail.\n4. **Queue Prompt** \n5. **Save Image** \n---\n\n### Mask tips\n\n- Cover the **whole** object plus any shadow/reflection you want removed; a tight mask often leaves a halo — raise `dilate_pixels`.\n- Best quality is near **~1 MP** and aspect ratios between **1:2** and **2:1** (per BFL guidance); very unusual sizes may look worse.\n"
