Grow Mask With Blur

GrowMaskWithBlur

# GrowMaskWithBlur - mask: Input mask or mask batch - expand: Expand or contract mask or mask batch by a given amount - incremental_expandrate: increase expand rate by a given amount per frame - tapered_corners: use tapered corners - flip_input: flip input mask - blur_radius: value higher than 0 will blur the mask - lerp_alpha: alpha value for interpolation between frames - decay_factor: decay value for interpolation between frames - fill_holes: fill holes in the mask (slow)

Example

JSON Example

{
  "class_type": "GrowMaskWithBlur",
  "inputs": {
    "mask": [
      "node_id",
      0
    ],
    "expand": 0,
    "incremental_expandrate": 0,
    "tapered_corners": true,
    "flip_input": false,
    "blur_radius": 0,
    "lerp_alpha": 1,
    "decay_factor": 1
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
mask	MASK	required	-	-
expand	INT	required	min: -16384, max: 16384, step: 1	0
incremental_expandrate	FLOAT	required	min: 0, max: 100, step: 0.1	0
tapered_corners	BOOLEAN	required	-	true
flip_input	BOOLEAN	required	-	false
blur_radius	FLOAT	required	min: 0, max: 100, step: 0.1	0
lerp_alpha	FLOAT	required	min: 0, max: 1, step: 0.01	1
decay_factor	FLOAT	required	min: 0, max: 1, step: 0.01	1
fill_holes	BOOLEAN	optional	-	false

Outputs

Index	Name	Type	Is List	Connection Reference
0	mask	MASK	No	["{node_id}", 0]
1	mask_inverted	MASK	No	["{node_id}", 1]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this GrowMaskWithBlur node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• mask (MASK): ["5", 0]
• mask_inverted (MASK): ["5", 1]
