  • 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.

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
Nearest
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
