ComfyUI-SaveImageWithMetaData

日本語版READMEはこちら。

• Custom node for ComfyUI.
• Add a node to save images with metadata (PNGInfo) extracted from the input values of each node.
• Since the values are extracted dynamically, values output by various extension nodes can be added to metadata.

Installation

cd <ComfyUI directory>/custom_nodes
git clone https://github.com/nkchocoai/ComfyUI-SaveImageWithMetaData.git

Nodes

Save Image With Metadata

• Saves the images received as input as an image with metadata (PNGInfo).
• Metadata is extracted from the input of the KSampler node found by sampler_selection_method and the input of the previously executed node.
  • Target KSampler nodes are the key of SAMPLERS in the file py/defs/samplers.py and the file in py/defs/ext/.

filename_prefix

• The string (Key) specified in filename_prefix will be replaced with the retrieved information.

Key	Information to be replaced
%seed%	seed value
%width%	Image width
%height%	Image height
%pprompt%	Positive Prompt
%pprompt:[n]%	first n characters of Positive Prompt
%nprompt%	Negative Prompt
%nprompt:[n]%	First n characters of Negative Prompt
%model%	Checkpoint name
%model:[n]%	First n characters of Checkpoint name
%date%	Date of generation(yyyyMMddhhmmss)
%date:[format]%	Date of generation

• See the following table for the identifier specified by [format] in %date:[format]%.

Identifier	Description
yyyy	year
MM	month
dd	day
hh	hour
mm	minute
ss	second

sampler_selection_method

• Specifies how to select a KSampler node that has been executed before this node.

Farthest

• Selects the farthest KSampler node from this node.
• Example: In everywhere_prompt_utilities.png, select the upper KSampler node (seed=12345).

Nearest

• Select the nearest KSampler node to this node.
• Example: In everywhere_prompt_utilities.png, select the bottom KSampler node (seed=67890).

By node ID

• Select the KSampler node whose node ID is sampler_selection_node_id.

Create Extra MetaData

• Specifies metadata to be added to the image to be saved.
• Example: In extra_metadata.png.

Metadata to be given

• Positive prompt
• Negative prompt
• Steps
• Sampler
• CFG Scale
• Seed
• Clip skip
• Size
• Model
• Model hash
• VAE
  • It is referenced from the input of SaveImageWithMetadata node, not KSampler node.
• VAE hash
  • It is referenced from the input of SaveImageWithMetadata node, not KSampler node.
• Loras
