ComfyUI Node: FL Pixel Art

FL Pixel Art:

The FL_PixelArtShader node is designed to transform your images into pixel art, giving them a retro, blocky appearance reminiscent of classic video games. This node applies a pixelation effect to the input images, allowing you to control the size of the pixels and the depth of colors used in the final output. By adjusting these parameters, you can achieve a wide range of artistic effects, from subtle pixelation to highly stylized, low-resolution graphics. This node is particularly useful for AI artists looking to add a unique, nostalgic touch to their digital artwork.

FL Pixel Art Input Parameters:

images

This is the primary input parameter where you provide the images you want to transform into pixel art. The node processes each image individually, applying the pixelation effect based on the specified settings.

pixel_size

The pixel_size parameter controls the size of the pixels in the output image. A larger value results in bigger, more noticeable pixels, while a smaller value creates a finer, more detailed pixelation effect. The default value is 100.0, with a minimum of 1.0 and a maximum of 1000.0, adjustable in steps of 1.0. Adjusting this parameter allows you to fine-tune the level of pixelation to suit your artistic vision.

color_depth

The color_depth parameter determines the number of colors used in the pixelated image. A lower value reduces the color palette, creating a more stylized and abstract look, while a higher value retains more of the original image's color detail. The default value is 50.0, with a minimum of 1.0 and a maximum of 255.0, adjustable in steps of 1.0. This parameter is essential for achieving the desired balance between color richness and the classic pixel art aesthetic.

FL Pixel Art Output Parameters:

IMAGE

The output of the FL_PixelArtShader node is an image that has been transformed into pixel art. This output retains the original dimensions of the input image but with the applied pixelation and color depth adjustments. The resulting image can be used directly in your projects or further processed with other nodes to achieve more complex effects.

FL Pixel Art Usage Tips:

• Experiment with different pixel_size values to find the perfect balance between detail and pixelation for your specific image.
• Use lower color_depth values to create a more abstract and stylized look, which can be particularly effective for creating retro game graphics or unique digital art pieces.
• Combine the FL_PixelArtShader node with other nodes to layer multiple effects and create more complex and interesting visuals.

FL Pixel Art Common Errors and Solutions:

"CUDA out of memory"

• Explanation: This error occurs when the GPU does not have enough memory to process the image.
• Solution: Try reducing the size of the input images or processing them in smaller batches to avoid exceeding the GPU memory limits.

"Invalid input image format"

• Explanation: This error indicates that the input image format is not supported by the node.
• Solution: Ensure that the input images are in a compatible format, such as PNG or JPEG, and that they are correctly loaded into the node.

"Pixel size out of range"

• Explanation: This error occurs when the pixel_size parameter is set outside the allowed range.
• Solution: Adjust the pixel_size parameter to be within the range of 1.0 to 1000.0.

"Color depth out of range"

• Explanation: This error occurs when the color_depth parameter is set outside the allowed range.
• Solution: Adjust the color_depth parameter to be within the range of 1.0 to 255.0.
