# ComfyUI-CoCoTools_IO
|
|
|
|
A set of nodes focused on advanced image I/O operations, particularly for EXR file handling.
|
|
|
|
## Features
|
|
- Advanced EXR image input with multilayer support
|
|
- EXR layer extraction and manipulation
|
|
- High-quality image saving with format-specific options
|
|
- Standard image format loading with bit depth awareness
|
|
|
|
|
|
## Installation for comfyui portable (tested on 0.3.14)
|
|
|
|
from the python_embeded/ folder
|
|
|
|
```bash
|
|
python.exe -m pip install -r ./ComfyUI/custom_nodes/ComfyUI-CoCoTools/requirements.txt
|
|
```
|
|
|
|
### Manual Installation
|
|
1. Clone the repository into your ComfyUI `custom_nodes` directory
|
|
2. Install dependencies
|
|
3. Restart ComfyUI
|
|
|
|
|
|
|
|
## Current Nodes
|
|
|
|
### Image I/O
|
|
- **Image Loader**: Load standard image formats (PNG, JPG, WebP, etc.) with proper bit depth handling
|
|
- **Load EXR**: Comprehensive EXR file loading with support for multiple layers, channels, and cryptomatte data
|
|
- **Load EXR Layer by Name**: Extract specific layers from EXR files (similar to Nuke's Shuffle node)
|
|
- **Cryptomatte Layer**: Specialized handling for cryptomatte layers in EXR files
|
|
- **Image Saver**: Save images in various formats with format-specific options (bit depth, compression, etc.)
|
|
|
|
### Image Processing
|
|
- **Colorspace**: Convert between sRGB and Linear colorspaces
|
|
- **Z Normalize**: Normalize depth maps and other single-channel data
|
|
|
|
|
|
## To-Do
|
|
#### IO
|
|
- [x] Implement proper EXR loading
|
|
- [ ] Implement EXR sequence loader
