ImageToMask (🚫Deprecated)(imageToMask)

Description

Converts an input image into a mask by extracting a single RGB color channel. The selected channel determines the value of each pixel in the output mask, while the other channels are ignored.

This node is part of the EasyUse/🚫 Deprecated category and is marked as deprecated.

Inputs

Usage Notes

• This node is deprecated and may be removed in a future release. Prefer the built-in ComfyUI ImageToMask node when available.
• The output mask is a single-channel image, so the selected channel controls the brightness and opacity of the mask.
• The node does not use an alpha channel; only the red, green, or blue channel is extracted.
