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.
Resolution Machine: Quick selection of model-specific image resolutions for popular models.

🧩 Node Features

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.

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.

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.

Model-aware Resolution Selection: Choose from a list of recommended resolutions for each supported model.
Auto-populate Width/Height: Selecting a resolution automatically fills in the correct width and height.
Manual Override: You can manually set width/height, which clears the preset selection.
Supports Many Models: Includes presets for SD1.5, SDXL, Illustrious XL, Pony XL, Flux.1 Dev, Qwen-Image, Wan2.2-S2V, SD3.5 Large, Lumina-Image 2.0, and more.
UI Integration: Intuitive dropdowns for model and resolution selection in the ComfyUI interface.
