中文说明 | Changelog

KayTool is a custom node utility package developed for ComfyUI. I plan to add more features in the future.

Current Features:

ColorAdjustment Node Feature Description

  • Supports adjustments for image exposure, contrast, color temperature, tint, and saturation

    • Exposure and Contrast: Range from -100 to +100
    • Color Temperature: Range from -100 to +100, where negative values add blue and positive values add yellow
    • Tint: Range from -100 to +100, where negative values add green and positive values add magenta
    • Saturation: Range from -100 to +100

  • Provides a selection list of popular Instagram-style filters for easy application.

    • All filters are sequentially numbered, with an added "None" option to apply no filter

  • Customizable filter strength

    • Strength ranges from 0 to 100 (0 means no filter applied, 100 means full filter application)

  • Option to "apply all filters" generates and returns a sequence of images with each filter effect applied

  • After adjusting exposure, contrast, color temperature, tint, and saturation, the selected filter is applied

CustomSaveImage Node Feature Description (English)

  • Choose the image format for saving (PNG or JPG)
  • Customizable JPG image quality (0-100)
  • Supports two color profiles (sRGB IEC61966-2.1 and Adobe RGB (1998))
    • When Adobe RGB is selected, the image is automatically converted to the Adobe RGB color space to ensure color accuracy
  • Option to save metadata (including workflow information, author, copyright info, and custom prompts)
  • Customizable metadata fields:
    • Author
    • Copyright Info
  • Automatically generates a unique filename to ensure each saved image has a distinct name
  • Automatically creates an output folder output/Custom_Save_Image to store all generated images
  • When saved in PNG format, metadata is stored as PNG information (PngInfo); when saved in JPG format, metadata is stored in EXIF format

Additional Notes:

  • To save in JPG format, the metadata option must be set to False.
  • When saving with metadata (workflow information), the format will automatically switch to PNG, and any JPG settings will be ignored.
  • For smaller file sizes without noticeable quality loss, set the JPG quality to 40. Lower values may cause visible compression artifacts (blockiness).

Installation and Usage:

Clone this project into your ComfyUI/custom_nodes directory, and make sure to place the sRGB Profile.icc and AdobeRGB1998.icc files in the resources directory.
