    🚀 Overview

    SATA Utility Node Suite is a collection of custom nodes for ComfyUI designed to enhance your image processing and workflow experience.
    It includes:

    • Upscale Machine: High-quality model-based image upscaling with aspect-ratio preserving rescale.
    • Prompt Machine: Easy prompt selection from a CSV for positive/negative prompt workflows.
    • Touchpad Pan & Zoom: Seamless navigation for large images in the ComfyUI preview panel.

    🧩 Node Features

    🖼️ Upscale Machine

    • Model-based Upscaling: Uses custom or pre-trained models from the upscale_models folder.
    • Aspect Ratio Preserving Rescale: Output size is always original size × rescale factor.
    • CPU-based Rescaling: Efficient resizing using OpenCV.
    • Supersampling: Optional detail preservation for downscaling/fractional resizing.
    • Rounding Modulus: Ensures output dimensions align with model/UI constraints.
    • Dual Output: Returns both the processed image and a help/documentation link.

    💬 Prompt Machine

    • CSV-based Prompt Selection: Select prompt sets from a CSV file (prompts.csv).
    • Positive/Negative Output: Outputs both positive and negative prompts as strings.
    • Easy Integration: Designed for use in prompt-driven workflows.

    🖱️ Touchpad Pan & Zoom

    • Preview Navigation: Enables smooth pan and zoom for large images in the ComfyUI preview panel.
    • User Experience: Makes inspecting high-res outputs fast and intuitive.
