    Apex Artist - ComfyUI Image Resize Node

    Professional image resizing node for ComfyUI with advanced algorithms and aspect ratio handling.

    Version ComfyUI Python

    Features

    🎯 Multiple Resize Algorithms

    • Lanczos - Highest quality for most use cases
    • Bicubic - Excellent for smooth gradients
    • Bilinear - Fast with decent quality
    • Nearest - Perfect for pixel art
    • Box - Optimized for downscaling
    • Hamming - Alternative high-quality option

    📐 Smart Aspect Ratio Handling

    • Keep Proportions - Maintains original aspect ratio
    • Stretch Mode - Direct resize ignoring proportions
    • Automatic dimension rounding to multiples of 8

    ✂️ Crop & Fill Options

    When maintaining aspect ratios:

    • Crop Center - Crops from center of image
    • Crop Top - Keeps top portion of image
    • Crop Bottom - Keeps bottom portion of image
    • Pad Center - Adds padding centered
    • Pad Top - Adds padding at bottom
    • Pad Bottom - Adds padding at top

    🎨 Advanced Options

    • Padding Colors: Black, White, Gray, Transparent
    • Resize Factor: Quick scaling multiplier (0.1x - 8.0x)
    • Post-Sharpening: Optional enhancement after resize
    • Batch Processing: Handles multiple images efficiently

    Installation

    Method 1: Git Clone (Recommended)

    cd ComfyUI/custom_nodes
git clone https://github.com/ApexArtist/apex-artist-comfyui.git

    Method 2: Manual Download

    1. Download the repository as ZIP
    2. Extract to ComfyUI/custom_nodes/apex-artist-comfyui/
    3. Restart ComfyUI

    Method 3: ComfyUI Manager

    1. Open ComfyUI Manager
    2. Search for "Apex Artist"
    3. Click Install

    Usage

    1. Add the Node: Find "Apex Artist - Image Resize" in the node menu under "Apex Artist" category
    2. Connect Input: Connect your image output to the image input
    3. Set Dimensions: Configure width and height (auto-rounded to multiples of 8)
    4. Choose Algorithm: Select resize method based on your needs
    5. Configure Handling: Set aspect ratio and crop/pad preferences

    Quick Start Example

    Image → Apex Artist → Save Image

    Algorithm Guide

    When to Use Each Algorithm:

    • Lanczos: Best general-purpose choice, excellent quality
    • Bicubic: Great for photographic images with smooth transitions
    • Bilinear: Fast processing, good for real-time applications
    • Nearest: Essential for pixel art, maintains sharp edges
    • Box: Optimal for significant downscaling
    • Hamming: Alternative high-quality option, similar to Lanczos

    Aspect Ratio Handling:

    • Crop Methods: Remove parts of image to fit exact dimensions
    • Pad Methods: Add borders to maintain full image content
    • Stretch: Distort image to fit exact dimensions

    Examples

    High-Quality Photo Resize

    Settings:
- Algorithm: Lanczos
- Keep Proportion: True
- Method: Pad Center
- Pad Color: Black

    Pixel Art Upscaling

    Settings:
- Algorithm: Nearest
- Keep Proportion: True
- Method: Crop Center

    Quick Batch Processing

    Settings:
- Algorithm: Bilinear
- Resize Factor: 0.5
- Keep Proportion: True

    Requirements

    • ComfyUI (latest version)
    • Python 3.8+
    • PIL (Pillow) - included with ComfyUI
    • PyTorch - included with ComfyUI
    • NumPy - included with ComfyUI

    Troubleshooting

    Common Issues:

    Node not appearing in menu:

    • Restart ComfyUI completely
    • Check console for error messages
    • Verify file placement in custom_nodes directory

    Memory errors with large images:

    • Use smaller resize factors
    • Process images individually instead of batches

    Quality issues:

    • Try Lanczos or Bicubic for better quality
    • Enable post-sharpening for crisp results
    • Avoid excessive upscaling (>4x)
