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
  • Model name
  • Model hash
  • Strength model
  • Strength clip
• Embeddings
  • Name
  • Hash
• If batch size >= 2 :
  • Batch index
  • Batch size
• Hashes
  • Model, Loras, Embeddings
  • For Civitai
