ComfyUI Node: ImageMagick Shade

ImageMagick Shade:

The ImageMagick Shade node is designed to apply a shading effect to an image, simulating the appearance of a light source casting shadows and highlights. This effect can add depth and dimension to your images, making them appear more three-dimensional and visually interesting. The shading effect is controlled by parameters such as azimuth and elevation, which determine the direction and angle of the light source. Additionally, you can choose to apply the shading in grayscale or color, allowing for a variety of artistic effects. This node is particularly useful for creating dramatic lighting effects and enhancing the visual appeal of your images.

ImageMagick Shade Input Parameters:

image

The image parameter is the input image to which the shading effect will be applied. This should be an image file that you want to enhance with shading.

gray

The gray parameter is a boolean option that determines whether the shading effect is applied in grayscale or color. If set to True, the shading will be in grayscale; if False, it will retain the original colors of the image. The default value is False.

azimuth

The azimuth parameter controls the direction of the light source in degrees. It ranges from 0.0 to 1024.0, with a default value of 0.0. Adjusting this parameter changes the horizontal angle of the light source, affecting the direction of the shadows and highlights.

elevation

The elevation parameter controls the angle of the light source above the horizon in degrees. It ranges from 0.0 to 1024.0, with a default value of 0.0. Adjusting this parameter changes the vertical angle of the light source, affecting the intensity and position of the shadows and highlights.

ImageMagick Shade Output Parameters:

image

The output parameter is the image with the applied shading effect. This enhanced image will have added depth and dimension, with shadows and highlights based on the specified azimuth and elevation parameters.

ImageMagick Shade Usage Tips:

• Experiment with different azimuth and elevation values to achieve the desired lighting effect. Small adjustments can significantly change the appearance of the shadows and highlights.
• Use the gray parameter to create dramatic black-and-white shading effects, which can add a classic or artistic touch to your images.
• Combine the Shade node with other ImageMagick nodes, such as Sharpen or Contrast, to further enhance the visual impact of your images.

ImageMagick Shade Common Errors and Solutions:

Invalid image input

• Explanation: The input provided is not a valid image file.
• Solution: Ensure that the input is a valid image file format supported by ImageMagick.

Azimuth or elevation out of range

• Explanation: The azimuth or elevation value is outside the acceptable range of 0.0 to 1024.0.
• Solution: Adjust the azimuth and elevation values to be within the specified range.

Gray parameter not boolean

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