ComfyUI Node: Save Image to Path

Save Image to Path:

The SaveImagetoPath node is designed to save an image to a specified file path on your system. This node is particularly useful for AI artists who need to store their generated images in a structured and organized manner. By specifying the path and format, you can ensure that your images are saved exactly where you want them, with the desired quality and compression settings. This node supports various image formats such as JPEG, PNG, and BMP, and allows for customization of parameters like JPEG quality and PNG compression level. The main goal of this node is to provide a flexible and efficient way to save images, making it easier for you to manage and access your artwork.

Save Image to Path Input Parameters:

path

The path parameter specifies the file path where the image will be saved. It should be a string representing the directory and filename. This parameter is crucial as it determines the location and name of the saved image. Ensure that the path is valid and that you have write permissions to the specified directory.

image_format

The image_format parameter defines the format in which the image will be saved. Supported formats include .jpg, .png, and .bmp. This parameter affects the quality and compression of the saved image. For example, JPEG format allows for quality adjustment, while PNG supports lossless compression.

image

The image parameter is a tensor representing the image to be saved. This tensor should have three channels (RGB) and be in the range of 0 to 1. The image tensor is the core input that will be processed and saved to the specified path.

save_sequence

The save_sequence parameter is a boolean that determines whether to save the image as part of a sequence. If set to true, the node will append a sequence number to the filename to avoid overwriting existing files. This is useful for saving multiple images in a series.

jpg_quality

The jpg_quality parameter specifies the quality of the saved JPEG image, ranging from 1 (lowest quality) to 95 (highest quality). This parameter is only applicable if the image_format is set to .jpg. Higher quality values result in larger file sizes.

png_compress_level

The png_compress_level parameter defines the compression level for PNG images, ranging from 0 (no compression) to 9 (maximum compression). This parameter is only applicable if the image_format is set to .png. Higher compression levels result in smaller file sizes but may take longer to save.

Save Image to Path Output Parameters:

filename

The filename parameter is a string representing the name of the saved image file. This output is useful for verifying the exact name of the saved file, especially when saving images as part of a sequence.

subfolder

The subfolder parameter is a string representing the subfolder where the image was saved. This output helps you locate the saved image within the specified directory structure.

type

The type parameter indicates the type of the output, which is output in this case. This output is mainly for internal use and helps in categorizing the saved file.

Save Image to Path Usage Tips:

• Ensure that the path parameter is set to a valid directory where you have write permissions to avoid errors during the save process.
• Use the save_sequence parameter to prevent overwriting existing files when saving multiple images in a series.
• Adjust the jpg_quality and png_compress_level parameters to balance between image quality and file size based on your needs.

Save Image to Path Common Errors and Solutions:

"can't take image batch as input, got {img.shape[0]} images"

• Explanation: This error occurs when the input image tensor has more than three dimensions, indicating a batch of images rather than a single image.
• Solution: Ensure that the input tensor represents a single image with three channels (RGB).

"image must have 3 channels, but got {img.shape[0]} channels"

• Explanation: This error occurs when the input image tensor does not have exactly three channels.
• Solution: Verify that the input tensor is in RGB format with three channels.

"Unsupported file format: {ext}"

• Explanation: This error occurs when the specified image_format is not supported by the node.
• Solution: Use one of the supported formats: .jpg, .png, or .bmp.

"File path is invalid or not writable"

• Explanation: This error occurs when the specified path is invalid or the directory is not writable.
• Solution: Check the file path for correctness and ensure you have write permissions to the directory.
