Draw Mask

Creates a custom mask by drawing on a canvas with adjustable size, brush, and grayscale color. Outputs a mask tensor for downstream processing.

Quick Start

1. Set canvas width and height.
2. Adjust brush size and color as needed.
3. Draw on the canvas to create your mask.
4. Use the output mask in your workflow.

Setup Guide

1. Configure Canvas

1. Choose desired width and height for the mask.
2. Set brush size and color for drawing.

2. Draw and Export

1. Draw on the canvas using the configured brush.
2. Export the mask for use in other nodes.

Basic Usage

Creating a Custom Mask

• Draw directly on the canvas to define mask regions.
• Adjust brush size for fine or broad strokes.
• Use grayscale brush color for mask intensity.

Configuration

Required Inputs

Field	Description	Type	Example
canvas	The base64-encoded canvas image to draw the mask on.	CANVAS	(UI-provided)
width	Width of the mask in pixels.	INT	512
height	Height of the mask in pixels.	INT	512
brush_size	Size of the drawing brush in pixels.	INT	10
brush_color	Grayscale color value for the brush (0=black, 255=white).	INT	255

Optional Inputs

None

Outputs

Field	Description	Example
mask	The generated mask tensor.	(Tensor)

Best Practices

Drawing Masks

• Use a larger brush for broad areas, smaller for details.
• Set brush color to 255 for full mask, lower for partial transparency.

Workflow Integration

• Combine with other masking nodes for complex effects.
• Resize canvas to match target image dimensions for best results.

Troubleshooting

Common Issues

• Mask appears empty: Ensure you have drawn on the canvas and brush color is not set to 0.
• Output size mismatch: Set width and height to match your target image.
