    • 🖼️ Image Processing Nodes

    🎨 Image Glitcher

    Create authentic glitch art effects with chromatic aberration and scanlines!

    Based on the HTML image glitcher by Felix Turner (original demo).

    Parameters:

  • glitchiness (0-100): Controls glitch corruption and chromatic aberration intensity
  • brightness (0-100): Brightens the image, useful with scanlines enabled
  • scanlines (toggle): Adds authentic CRT TV scanlines

    • Usage: Simply connect an image input and adjust parameters to taste.

    🌈 Color Stylizer

    Selective color isolation – pick a single color and desaturate everything else!

    Perfect for creating dramatic color pop effects like in *Sin City* or *Schindler’s List*.

    Parameters:

  • target_color: The color to preserve (hex or RGB)
  • tolerance: How closely colors must match to be preserved
  • desaturation: How much to desaturate non-matching colors

    • Usage: Connect an image and specify which color to keep while everything else becomes grayscale.

    🤖 AI & Utility Nodes

    💬 Query Local LLM

    Send queries to OpenAI-compatible APIs and get text responses in your workflow!

  • System and user message support
  • Temperature and token control

    • Usage:

    • 📐 SDXL Workflow Nodes

    📏 SDXL Resolution Picker

    Choose from all pre-trained SDXL resolutions in one convenient dropdown!

    Unlike other resolution pickers, this includes the complete list of SDXL-trained resolutions for optimal quality.

    Features:

  • All official SDXL resolutions (1024×1024, 1152×896, 1216×832, etc.)
  • Aspect ratio labels
  • Portrait, landscape, and square formats
  • Single selection output

    • Why use this? SDXL was trained on specific resolutions – using them gives better results than arbitrary sizes!

    ✂️ SDXL Resolution Split

    Split SDXL Resolution output into separate width and height values.

    Purpose: Reduces workflow clutter by passing resolution as a single connection, then splitting where needed.

    Usage:

  • Connect SDXL Resolution Picker output to this node
  • Get separate width and height outputs
  • Connect to your Empty Latent Image or other nodes

    • Benefit: One connection instead of two = cleaner workflow graphs!
