ComfyUI Node: 🌟 Neon Glow

🌟 Neon Glow:

The NeonGlowNode is a powerful tool designed to add vibrant neon glow effects to images, enhancing their visual appeal with a modern and dynamic touch. This node is particularly useful for creating striking visual effects that mimic the appearance of neon lights, which can be used in various creative projects such as digital art, graphic design, and visual storytelling. By applying a neon glow, you can highlight specific areas of an image, create a sense of depth, or simply add a unique artistic flair. The node offers flexibility in terms of color selection, intensity, and glow size, allowing you to customize the effect to suit your artistic vision. Additionally, features like inner and outer glow options, edge detection, and pulsating effects provide further control over the final output, making it a versatile choice for artists looking to experiment with light effects in their work.

🌟 Neon Glow Input Parameters:

image

The image parameter is the input image to which the neon glow effect will be applied. It serves as the base layer for the effect, and the quality and resolution of this image will directly impact the final result. This parameter is required and should be provided in a compatible image format.

glow_color

The glow_color parameter determines the color of the neon glow effect. You can choose from predefined colors such as cyan, magenta, yellow, red, green, blue, purple, and orange. The default color is cyan. This parameter allows you to match the glow effect with the overall color scheme of your project or to create contrasting highlights.

intensity

The intensity parameter controls the brightness of the neon glow effect. It ranges from 0.0 to 2.0, with a default value of 0.8. A higher intensity will result in a more pronounced glow, while a lower intensity will produce a subtler effect. Adjusting this parameter allows you to fine-tune the visual impact of the glow.

glow_size

The glow_size parameter specifies the size of the glow effect, ranging from 0.1 to 1.0, with a default value of 0.3. This parameter affects how far the glow extends from the edges of the detected features in the image. A larger glow size will create a more diffuse effect, while a smaller size will keep the glow closer to the edges.

edge_threshold

The edge_threshold parameter is an optional setting that influences the sensitivity of edge detection in the image. It ranges from 0.1 to 1.0, with a default value of 0.3. A lower threshold will detect more edges, potentially resulting in a more detailed glow effect, while a higher threshold will focus on more prominent edges.

inner_glow

The inner_glow parameter is a boolean option that enables or disables the inner glow effect. By default, it is set to True. When enabled, the inner glow adds a soft glow inside the edges of the detected features, enhancing the depth and richness of the effect.

outer_glow

The outer_glow parameter is a boolean option that controls the outer glow effect. It is set to True by default. When activated, the outer glow extends the neon effect beyond the edges, creating a halo-like appearance that can add a dramatic flair to the image.

pulsate

The pulsate parameter is a boolean option that, when enabled, adds a pulsating effect to the neon glow. This creates a dynamic, rhythmic change in the glow's intensity, simulating the flickering of neon lights. The default setting is False, and enabling it can add an animated quality to the effect.

🌟 Neon Glow Output Parameters:

IMAGE

The output of the NeonGlowNode is an IMAGE that has been enhanced with the neon glow effect. This output image retains the original content while overlaying the customized glow effect, resulting in a visually striking and enhanced version of the input image. The output can be used directly in digital art projects or further processed in other nodes for additional effects.

🌟 Neon Glow Usage Tips:

• Experiment with different glow_color options to see how they interact with the colors in your image, creating either complementary or contrasting effects.
• Adjust the intensity and glow_size parameters to balance the glow effect with the details of your image, ensuring that the glow enhances rather than overwhelms the original content.
• Use the pulsate option to add a dynamic element to your images, especially if you plan to use the output in animations or interactive media.

🌟 Neon Glow Common Errors and Solutions:

"KeyError: 'glow_color'"

• Explanation: This error occurs when an invalid color is specified for the glow_color parameter.
• Solution: Ensure that the glow_color is set to one of the predefined options: cyan, magenta, yellow, red, green, blue, purple, or orange.

"ValueError: Intensity out of range"

• Explanation: This error indicates that the intensity value is outside the allowed range of 0.0 to 2.0.
• Solution: Adjust the intensity parameter to be within the specified range, using values between 0.0 and 2.0.

"TypeError: Image input is not valid"

• Explanation: This error suggests that the input provided for the image parameter is not in a compatible format.
• Solution: Verify that the input image is in a supported format and correctly loaded into the node.
