# ← ComfyTV Mask

> **Out-bridge**: extract **MASK** tensor from **COMFYTV_IMAGE** (often PNG with alpha). **No ▶ Run** — loads on Queue.

## What this node does

ComfyTV **Cutout** and alpha PNGs output **`COMFYTV_IMAGE`**. ComfyUI inpaint / ControlNet need **`MASK`**. This node inverts **alpha** to mask (same as `_load_image_tensor` logic), matching ComfyUI conventions.

Shares URL input with **← ComfyTV Image**: one branch RGB, one branch mask.

## When to use it

* ComfyTV **Cutout** → native **Inpaint**
* ComfyTV edit → ControlNet Inpaint
* Split one COMFYTV\_IMAGE: ← Image + ← Mask

## How it works

* Normal node, no Run.
* With alpha: `mask = 1.0 - alpha`; without: zeros.
* Output `[1,H,W]` float.

## Types

| Input           | Output         |
| --------------- | -------------- |
| `COMFYTV_IMAGE` | ComfyUI `MASK` |

## Parameters

### image

**COMFYTV\_IMAGE** with alpha preferred.

## Outputs

| Output   | Type         | Downstream          |
| -------- | ------------ | ------------------- |
| **MASK** | ComfyUI MASK | Inpaint, ControlNet |

## Step by step

1. **Cutout** or transparent PNG from ComfyTV.
2. Wire **← ComfyTV Mask** **image**.
3. MASK → Inpaint; RGB → **← ComfyTV Image**.

## FAQ

**Q: Wrong mask after Cutout?**\
A: Ensure PNG has alpha channel.

**Q: vs Inpaint Stage brush?**\
A: Inpaint Stage masks inside ComfyTV; this **exports** mask to native inpaint.
