ComfyUI Node: Preview Image (16 bit)

Preview Image (16 bit):

The PreviewImageHighPrec node is designed to provide a high-precision preview of images, specifically handling 16-bit PNG files. This node is particularly useful for AI artists who work with high dynamic range images and require accurate previews to assess the quality and details of their work. By leveraging 16-bit color depth, the node ensures that the preview maintains a high level of detail and color accuracy, which is crucial for tasks that demand precision. The node temporarily saves the image in a specified directory with a unique prefix, making it easy to manage and view the preview without affecting the original file.

Preview Image (16 bit) Input Parameters:

images

This parameter accepts the images that you want to preview. The input should be in the form of an image tensor, typically representing a 16-bit PNG file. The node processes these images to generate a high-precision preview, ensuring that the color depth and details are preserved. This parameter is essential for the node's operation as it defines the source material for the preview.

Preview Image (16 bit) Output Parameters:

This node does not explicitly define output parameters in the provided context. However, it is implied that the node generates a temporary high-precision preview image, which can be accessed from the specified temporary directory.

Preview Image (16 bit) Usage Tips:

• Ensure that your input images are in 16-bit PNG format to fully utilize the high-precision capabilities of this node.
• Use this node when you need to preview images with high dynamic range and color accuracy, especially in workflows involving detailed image editing or quality assessment.
• Regularly clean up the temporary directory to manage storage space, as the node saves preview images there.

Preview Image (16 bit) Common Errors and Solutions:

ColorMod: Only PNG files can be loaded in 16 bit color.

• Explanation: This error occurs when the input image is not a PNG file.
• Solution: Ensure that the input image is in PNG format before using this node.

Failed to read image!

• Explanation: This error indicates that the node was unable to read the input image file.
• Solution: Verify that the image file exists and is accessible. Check the file path and ensure it is correct.

Invalid image file: <image>

• Explanation: This error suggests that the specified image file is invalid or cannot be found.
• Solution: Double-check the file name and path to ensure they are correct. Make sure the file is located in the expected directory.
