A set of nodes for ComfyUI that can composite layer and mask to achieve Photoshop like functionality.
The "LayerMask: MaskGrow" node is part of the ComfyUI LayerStyle extension, designed to manipulate image masks within a ComfyUI workflow. This node enables users to adjust and enhance the structure of masks by inverting them, growing their size, and applying a blur effect. Such manipulations are essential in image processing tasks where precise control over mask boundaries is required, such as in compositional editing, selective filtering, or layer blending.
The "LayerMask: MaskGrow" node accepts the following inputs:
mask: This input accepts a "MASK" type, which represents the binary or grayscale mask that you wish to process. The mask should define the regions of interest within an image that require modification.
invert_mask: This is a boolean input with a default value of True. When enabled, the input mask is inverted, flipping its black and white regions. This can be useful when you want to switch the areas of focus and background.
grow: An integer value input with a default value of 4. It determines how much the mask should expand or contract. Positive values will grow the mask outward, while negative values will shrink it inward. The value can be adjusted between -999 and 999 in steps of 1.
blur: An integer value input with a default value of 4. This determines the level of blur applied to the expanded or contracted mask. The blur effect smoothens the mask's edges, ensuring a more natural transition. The blur range is from 0 to 999.
This node does not have optional inputs.
The "LayerMask: MaskGrow" node produces the following output:
In ComfyUI workflows, the "LayerMask: MaskGrow" node serves as a tool for refining and manipulating masks. It can be used in various scenarios, such as:
Layer Composition: Modifying masks to achieve more precise layer compositions by expanding or contracting areas.
Selective Effects: Preparing masks for selective application of image effects, filtering, or adjustments.
Mask Refinement: Smoothing or enhancing mask edges for more natural-looking edits.
To use this node effectively, you would typically integrate it at a point in your workflow where mask manipulation is necessary. Feed a mask into the node, adjust the "invert_mask", "grow", and "blur" parameters as needed, and then use the output mask in subsequent processing steps or nodes.
Inversion: The ability to invert the mask provides flexibility in deciding which areas of the image to target versus which to exclude.
Adjustable Growth: The growth parameter offers a versatile range for modifying the mask size, accommodating different levels of refinement.
Edge Smoothing: The built-in blur functionality ensures smoother transitions at the edges of masks, enhancing the visual quality of masked areas.
By incorporating these capabilities, the "LayerMask: MaskGrow" node empowers users with greater control over mask-based image modifications in their ComfyUI projects.
