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]%.

    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
