ComfyUI Node: ImageMagick Vignette

ImageMagick Vignette:

The ImageMagick Vignette node is designed to apply a vignette effect to your images, which darkens the corners and edges of the image, creating a subtle or dramatic focus on the center. This effect is often used in photography and digital art to draw attention to the main subject and add a professional touch to the image. The vignette effect can be customized by adjusting parameters such as radius, sigma, and the x and y offsets, allowing you to control the intensity and position of the vignette. This node leverages the powerful capabilities of ImageMagick to deliver high-quality results, making it an essential tool for enhancing your visual creations.

ImageMagick Vignette Input Parameters:

image

This parameter represents the input image to which the vignette effect will be applied. It is required and should be provided in a compatible image format.

radius

The radius parameter controls the size of the vignette effect. A larger radius will result in a more gradual transition from the center to the edges, while a smaller radius will create a more abrupt effect. The value can range from 0.0 to 1024, with a default of 0.0.

sigma

The sigma parameter determines the amount of blur applied to the vignette effect. Higher sigma values will produce a softer, more diffused vignette, while lower values will create a sharper transition. The value can range from 0.0 to 1024, with a default of 0.0.

x

The x parameter specifies the horizontal offset of the vignette effect from the center of the image. This allows you to shift the vignette effect to the left or right. The value can range from 0 to 1024, with a default of 0.

y

The y parameter specifies the vertical offset of the vignette effect from the center of the image. This allows you to shift the vignette effect up or down. The value can range from 0 to 1024, with a default of 0.

ImageMagick Vignette Output Parameters:

IMAGE

The output is the processed image with the applied vignette effect. This image will have the corners and edges darkened according to the specified parameters, enhancing the focus on the central area.

ImageMagick Vignette Usage Tips:

• Experiment with different radius and sigma values to achieve the desired intensity and softness of the vignette effect.
• Use the x and y parameters to position the vignette effect in a way that best complements the composition of your image.
• Combining the vignette effect with other ImageMagick nodes, such as Blur or Sharpen, can create more complex and visually appealing results.

ImageMagick Vignette Common Errors and Solutions:

Invalid image format

• Explanation: The input image is not in a compatible format.
• Solution: Ensure that the input image is in a supported format such as JPEG, PNG, or TIFF.

Radius or sigma value out of range

• Explanation: The radius or sigma parameter is set outside the allowable range.
• Solution: Adjust the radius and sigma values to be within the range of 0.0 to 1024.

Invalid x or y offset

• Explanation: The x or y parameter is set outside the allowable range.
• Solution: Ensure that the x and y values are within the range of 0 to 1024.
