ComfyUI-XJNodes

A modular collection of custom nodes for ComfyUI, organized by data type for easy navigation and maintenance.

Note: This repository is primarily for personal use and experimentation.

Available Nodes

This package provides custom nodes organized into four main categories:

Image Nodes

Loaders:

• Load Images From Dir Batch - Load multiple images from a directory as a batch, with options for image cap, start index, and recursive loading
• Load Images From Dir List - Load images from a directory as a list (each image separate), supports recursive directory traversal
• Load Image With Metadata - Load image from input/output directories with full metadata extraction (dimensions, format, PNG text chunks, workflow data)
• Load Image By Path - Simple loader that takes directory and filename as string inputs

Savers:

• Save Image With Metadata - Save images with embedded metadata, workflow, and custom text fields

Transforms:

• Image Transform - Apply transformations to images with specified parameters
• Image Random Transform - Apply random transformations to images for data augmentation

Scaling:

• Image Scale Calc - Calculate scaling dimensions for images
• Image Scale Megapixel - Scale images to target megapixel resolution

Batch:

• Image Grid - Arrange multiple images into a grid layout
• One Image From Batch - Extract a single image from a batch by index
• Image List Filter - Filter images from a list based on criteria
• Random Images From Batch - Randomly select images from a batch

Text Nodes

Loaders:

• Random Text From List - Select text from a numbered list widget (fixed or random selection)
• Random Text From File - Select text from .txt or .md files in input directory (supports comments with #, list items with -)
• Text List From File - Load all valid lines from a text file as a list

Info:

• Text File Info - Get information about text files (line count, etc.)

JSON:

• JSON Extractor - Extract values from JSON data structures

Primitives

Adapters:

• Scheduler Adapter - Adapter for ComfyUI scheduler compatibility
• Sampler Adapter - Adapter for ComfyUI sampler compatibility
• StringPass - Simple string passthrough utility

Integers:

• Int Offset - Add offset to integer values
• Integer Increment - Increment integer by a value
• Integer Decrement - Decrement integer by a value

Floats:

• Float Range List - Generate a list of float values within a range

Specialized

SUPIR:

• SUPIR Parameters - Helper node for SUPIR upscaling workflow parameters
