ComfyUI Node: SonarPreviewFilter

SonarPreviewFilter:

The SonarPreviewFilter node is designed to generate a preview of the sonar power filter's effect on an image. This node allows you to visualize the impact of various filter settings before applying them to your final output, making it easier to fine-tune parameters and achieve the desired artistic effect. By providing a customizable preview, it helps you save time and resources by enabling quick iterations and adjustments. The main goal of this node is to offer a user-friendly interface for previewing and tweaking sonar power filter settings, ensuring that you can achieve the best possible results in your AI art projects.

SonarPreviewFilter Input Parameters:

sonar_power_filter

This parameter represents the sonar power filter that you want to preview. It is a complex object that contains the filter's settings and behavior. By providing this filter, the node can generate a preview based on its current configuration. There are no specific minimum or maximum values for this parameter, as it is an object rather than a scalar value.

filter_gain

This parameter controls the gain applied to the filter. It adjusts the intensity of the filter effect, allowing you to increase or decrease its impact on the image. The default value is 1/3. Adjusting this parameter can help you achieve the desired balance between the original image and the filtered effect. The minimum value is 0, and the maximum value is 1.

kernel_gain

This parameter controls the gain applied to the filter's kernel. Similar to filter_gain, it adjusts the intensity of the kernel effect, which can influence the overall appearance of the filtered image. The default value is 1/3. By fine-tuning this parameter, you can enhance or soften the filter's impact. The minimum value is 0, and the maximum value is 1.

norm_factor

This parameter represents the normalization factor applied to the filter. It ensures that the filtered image maintains a consistent intensity level, preventing it from becoming too bright or too dark. The default value is 1.0. Adjusting this parameter can help you achieve a balanced and visually appealing result. The minimum value is 0, and there is no specific maximum value.

preview_size

This parameter defines the size of the preview image. It is specified as a string in the format "widthxheight" (e.g., "256x256"). The default value is "256x256". By adjusting this parameter, you can control the resolution of the preview, allowing you to see more or less detail depending on your needs. There are no specific minimum or maximum values, but common sizes range from 128x128 to 512x512.

SonarPreviewFilter Output Parameters:

preview_image

This parameter represents the generated preview image. It is a visual representation of the sonar power filter's effect based on the provided input parameters. The preview image allows you to see how the filter settings will impact your final output, making it easier to make adjustments and achieve the desired result. The output is typically an image file or an image object that can be displayed or saved.

SonarPreviewFilter Usage Tips:

• Experiment with different filter_gain and kernel_gain values to find the perfect balance for your image. Start with the default values and make small adjustments to see how they affect the preview.
• Use the preview_size parameter to generate a larger or smaller preview image, depending on your needs. A larger preview can help you see more detail, while a smaller preview can be generated more quickly.
• Adjust the norm_factor to ensure that your preview image maintains a consistent intensity level. This can help prevent the image from becoming too bright or too dark.

SonarPreviewFilter Common Errors and Solutions:

"Invalid preview size format"

• Explanation: The preview_size parameter is not in the correct format (e.g., "256x256").
• Solution: Ensure that the preview_size parameter is specified as a string in the format "widthxheight" (e.g., "256x256").

"Filter object is not provided"

• Explanation: The sonar_power_filter parameter is missing or not correctly specified.
• Solution: Provide a valid sonar power filter object as the sonar_power_filter parameter.

"Normalization factor out of range"

• Explanation: The norm_factor parameter is set to a value that is too low or too high.
• Solution: Adjust the norm_factor parameter to a reasonable value, typically between 0 and 2, to ensure a balanced preview image.
