Nodes Overview

🖼️ Image Manipulation

• Image Square Adapter Node

  • Fits an image into a target square size.
  • Features: Customizable fill color, resizing filters (lanczos, nearest, etc.), supersampling, and fitting modes (center, top, bottom).

• Image Resize And Crop Node

  • Resizes and crops an image to exact target dimensions.
  • Features: Alignment control (center, left-top, right-bottom, etc.) to choose which part of the image to keep.

• Auto Levels (Image)

  • Automatically adjusts contrast by stretching the histogram values.
  • Features: Configurable black/white points (percentiles) and channel-independent mode (for color correction) vs global mode (for contrast only).

• Image Extract Rect

  • Extracts a specific rectangular region from an image based on a corner selection.
  • Use Case: Useful for processing specific parts of an image (e.g., watermarks) separately.

• Image Combine Rect

  • Pastes a source image (patch) into a destination image at a specific corner.
  • Use Case: Re-combining patches processed by Image Extract Rect.

• Load Images From Folder

  • Loads all images (.png, .jpg, .jpeg) from a specified local folder path as a batch tensor.

📐 Resolution & Aspect Ratios

• Aspect Ratio (Mobile Devices)

  • Provides standard resolutions for popular mobile devices (iPhone, iPad, Samsung Galaxy, etc.).
  • Features: Options to swap dimensions (portrait/landscape), prescale, and upscale factors.

• Aspect Ratio (Popular)

  • Provides standard screen resolutions (Full HD, 4K, 8K, etc.).
  • Features: Similar scaling and orientation options.

• Resolution for 2-Stage Upscale

  • Helper node to calculate dimensions for upscaling workflows.
  • Features: aligned rounding (e.g. multiples of 8 or 16) and compression factor calculation.

🎥 Video

• Slider Comparison (Video)
  • Generates a video file comparing two images ("Before" and "After") with a moving slider divider.
  • Features: Customizable duration, frame rate, slider color, thickness, and output height. Uses moviepy.

🧮 Math & Utilities

• Math Operation (Min/Max)
  • Performs basic integer arithmetic: min, max, add, subtract, multiply, divide.
• Number Range
  • Generates a list of numbers (integers and floats) given a start, end, and step.
