What ComfyUI's ControlNet Auxiliary Preprocessors does in a ComfyUI graph
Converts ordinary RGB photos into DepthAnything maps, DWPose skeletons, LineArt drawings, and ZoeDepth maps for ControlNet.
On the canvas, this node accepts `image, resolution` and emits `IMAGE (depth, openpose, lineart, scribble)`. Every pin is color-coded by data type so you cannot accidentally wire a pixel `IMAGE` tensor into a `LATENT` pin without an intermediate encode step.
