ComfyUI Node: 🕹️PixelArt Detector (Image->)

🕹️PixelArt Detector (Image->):

The PixelArtDetectorToImage node is designed to process pixel art images, converting them into a format suitable for further manipulation and analysis. This node is particularly useful for AI artists who work with pixel art and need to ensure their images are correctly scaled and color-reduced for optimal use in various applications. The node detects the appropriate 1:1 pixel scale of the input image, ensuring that the pixel art retains its intended visual quality. Additionally, it offers an option to reduce the color palette of the image, which can be beneficial for creating a more cohesive and visually appealing result. By leveraging this node, you can streamline your pixel art workflow and achieve consistent, high-quality outputs.

🕹️PixelArt Detector (Image->) Input Parameters:

images

This parameter accepts a list of images in the form of torchTensors. These images are the ones you want to process using the PixelArtDetectorToImage node. The node will analyze each image to detect the appropriate pixel scale and optionally reduce the color palette.

reduce_palette

This boolean parameter determines whether the color palette of the image should be reduced. When set to enabled, the node will reduce the number of colors in the image, which can help in achieving a more uniform and visually appealing result. The default value is disabled.

reduce_palette_max_colors

This integer parameter specifies the maximum number of colors to retain in the image when the reduce_palette option is enabled. It allows you to control the extent of color reduction, with a minimum value of 1 and a maximum value of 256. The default value is 128, providing a balanced reduction that maintains image quality while simplifying the color palette.

🕹️PixelArt Detector (Image->) Output Parameters:

IMAGE

The output of this node is a processed image in the form of a torchTensor. This image has been scaled to the appropriate 1:1 pixel ratio and, if the reduce_palette option was enabled, has a reduced color palette. The output image is ready for further processing or use in your AI art projects.

🕹️PixelArt Detector (Image->) Usage Tips:

• To maintain the visual quality of your pixel art, ensure that the input images are in a high-resolution format before processing.
• Experiment with the reduce_palette_max_colors parameter to find the optimal number of colors for your specific project. A lower number of colors can create a more stylized look, while a higher number retains more detail.
• Use the reduce_palette option when you want to create a more cohesive and simplified color scheme for your pixel art.

🕹️PixelArt Detector (Image->) Common Errors and Solutions:

"Invalid image format"

• Explanation: This error occurs when the input images are not in the correct format (torchTensor).
• Solution: Ensure that your input images are converted to torchTensors before passing them to the node.

"Palette reduction failed"

• Explanation: This error can happen if the reduce_palette option is enabled but the image cannot be processed for color reduction.
• Solution: Check that the reduce_palette_max_colors parameter is set within the valid range (1-256). If the issue persists, try using a different image or adjusting the number of colors.

"Image scaling error"

• Explanation: This error indicates a problem with detecting the appropriate pixel scale for the input image.
• Solution: Verify that the input image is a valid pixel art image with clear pixel boundaries. If necessary, preprocess the image to enhance its pixel clarity before using the node.
