ComfyUI Node: FL Image Pixelator

FL Image Pixelator:

The FL_ImagePixelator node is designed to transform your images into pixelated art, providing a unique and creative effect that can add a retro or stylized look to your visuals. This node leverages advanced image processing techniques to apply pixelation, allowing you to control the scale and intensity of the effect. By adjusting parameters such as scale factor, kernel size, and modulation, you can achieve a wide range of pixelation styles, from subtle to highly pronounced. The node supports both PIL images and PyTorch tensors, making it versatile for different workflows. Whether you're looking to create pixel art, reduce image detail for artistic purposes, or simply experiment with new visual styles, the FL_ImagePixelator offers a powerful and flexible toolset to enhance your creative projects.

FL Image Pixelator Input Parameters:

image

This parameter accepts the image you want to pixelate. The image can be in the form of a PIL image or a PyTorch tensor. The node will process the image based on the provided scale factor, kernel size, and modulation settings.

scale_factor

The scale factor determines the degree of pixelation applied to the image. A lower scale factor results in finer pixelation, while a higher scale factor produces a more pronounced pixelated effect. The default value is 0.0500, with a minimum of 0.0100 and a maximum of 0.2000, adjustable in steps of 0.0100.

kernel_size

The kernel size defines the size of the kernel used in the image processing step. It affects the smoothing and blending of the pixelated image. The default value is 3, with a maximum of 10, adjustable in steps of 1.

modulation

The modulation parameter allows you to introduce a dynamic variation in the scale factor, creating a modulated pixelation effect. This can add an interesting visual rhythm to the pixelation. The default value is 0.0, with a minimum of 0.0 and a maximum of 1.0, adjustable in steps of 0.01.

FL Image Pixelator Output Parameters:

image

The output parameter is the pixelated image, which retains the same format as the input (either a PIL image or a PyTorch tensor). The pixelated image reflects the applied scale factor, kernel size, and modulation settings, providing a transformed version of the original image with the desired pixelation effect.

FL Image Pixelator Usage Tips:

• Experiment with different scale factors to achieve varying levels of pixelation, from subtle to extreme.
• Use the modulation parameter to add dynamic variations to the pixelation, creating a more visually interesting effect.
• Adjust the kernel size to control the smoothness and blending of the pixelated image, which can help in achieving the desired artistic style.
• Combine the FL_ImagePixelator with other image processing nodes to create complex and unique visual effects.

FL Image Pixelator Common Errors and Solutions:

• Solution: Adjust the scale factor to be within the range of 0.0100 to 0.2000.

Invalid kernel size

• Explanation: The kernel size provided is outside the acceptable range.
• Solution: Adjust the kernel size to be within the range of 1 to 10.

Modulation value out of range

• Explanation: The modulation value provided is outside the acceptable range.
• Solution: Adjust the modulation value to be within the range of 0.0 to 1.0.
