[![Version](https://img.shields.io/badge/Latest%20Release-0.1.0-brightgreen)](https://github.com/GarthTB/fast_image_stacker/releases)

A lightweight command-line tool for stacking 8/16-bit RGB images.

## Features

- **Stacking Modes**: Choose among `mean`, `max`, or `min` pixel stacking

- **High Precision**: 32-bit floating-point arithmetic for accurate results

- **Input Support**: Processes 8-bit or 16-bit RGB images ([complete list](https://docs.rs/image/0.25.6/image/enum.ImageFormat.html))

- **Output**: Saves result as 16-bit TIFF

- **Lightweight**: Minimal dependencies and fast execution

## Usage

1. Place all the images to be processed in a subfolder named `images` within the program directory, or manually select the folder.

2. Choose a mode.

## Technical Notes

### Image Requirements

- All input images must have identical dimensions (width × height)

- RGB color format (3 channels)

- Supported bit depths: 8 or 16 bits per channel

### Processing Workflow

- Calculation accuracy: 32-bit floating-point

- Stack using selected mode:

  - Mean: Average of all pixel values

  - Max: Highest pixel value across stack

  - Min: Lowest pixel value across stack
