ComfyUI Node: Create Gradient Mask

Create Gradient Mask:

The CreateGradientMask node is designed to generate a gradient mask, which transitions smoothly from black to white across the width of the image. This node is particularly useful for creating effects that require a gradual change in intensity, such as blending or fading effects in AI-generated art. The gradient can be customized in terms of its dimensions and can be inverted if needed. By adjusting the number of frames, you can create a sequence of gradient masks that change over time, adding dynamic visual effects to your projects.

Create Gradient Mask Input Parameters:

invert

The invert parameter is a boolean option that determines whether the gradient mask should be inverted. When set to True, the gradient will transition from white to black instead of black to white. This can be useful for creating reverse fading effects. The default value is False.

frames

The frames parameter specifies the number of frames or images in the batch. This allows you to create a sequence of gradient masks that change over time. The value must be an integer between 0 and 255, with a default value of 0. Increasing the number of frames can add dynamic visual effects to your project.

width

The width parameter defines the width of the gradient mask in pixels. It must be an integer between 16 and 4096, with a default value of 256. Adjusting the width allows you to control the horizontal resolution of the gradient.

height

The height parameter defines the height of the gradient mask in pixels. It must be an integer between 16 and 4096, with a default value of 256. Adjusting the height allows you to control the vertical resolution of the gradient.

Create Gradient Mask Output Parameters:

MASK

The MASK output is a tensor containing the generated gradient mask(s). This output can be used in various image processing tasks where a gradient effect is needed. The mask can be directly applied to images to create smooth transitions or blended effects.

Create Gradient Mask Usage Tips:

• To create a smooth fading effect, set the invert parameter to False and adjust the frames parameter to generate a sequence of gradient masks.
• For a reverse fading effect, set the invert parameter to True.
• Adjust the width and height parameters to match the resolution of the images you are working with to ensure the gradient mask fits perfectly.

Create Gradient Mask Common Errors and Solutions:

ValueError: Frames must be between 0 and 255

• Explanation: The frames parameter value is outside the allowed range.
• Solution: Ensure that the frames parameter is set to an integer between 0 and 255.

ValueError: Width must be between 16 and 4096

• Explanation: The width parameter value is outside the allowed range.
• Solution: Ensure that the width parameter is set to an integer between 16 and 4096.

ValueError: Height must be between 16 and 4096

• Explanation: The height parameter value is outside the allowed range.
• Solution: Ensure that the height parameter is set to an integer between 16 and 4096.

TypeError: Invert must be a boolean

• Explanation: The invert parameter is not set to a boolean value.
• Solution: Ensure that the invert parameter is set to either True or False.
