## Overview

Image Matrix Recombination is a professional-grade utility designed for precise color space manipulation and channel mixing. By applying a custom 3x3 transformation matrix to your image data, you can achieve advanced color grading, channel swapping, or specialized filter effects with mathematical accuracy.

## Inputs

- **Image File** (file): Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) for matrix recombination
- **Recombination Matrix** (textarea): 3x3 transformation matrix for color channel recombination. Format: \[\[r1,g1,b1\],\[r2,g2,b2\],\[r3,g3,b3\]\]
- **Output Format** (select): Choose output format or keep original. PNG recommended for maximum quality
- **Quality (1-100)** (number): Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size

## When to use

- When you need to perform custom color channel mixing for artistic or technical image processing.
- When converting images between specific color spaces using linear matrix transformations.
- When you want to isolate or swap specific color channels to create unique visual effects or diagnostic outputs.

## How it works

- Upload your source image file in any supported format like PNG, JPEG, or TIFF.
- Input your 3x3 transformation matrix in the required JSON-style array format.
- Select your preferred output format and quality settings to maintain image integrity.
- Process the image to apply the matrix calculation to every pixel's RGB values.

## Use cases

- Creating custom monochrome or sepia-toned filters through specific channel weighting.
- Swapping color channels (e.g., BGR to RGB) for compatibility with specific hardware or software pipelines.
- Performing linear color correction by adjusting channel intensity via matrix coefficients.

## Frequently asked questions

### What is a 3x3 transformation matrix?

It is a mathematical grid used to calculate new RGB values for each pixel by multiplying the original channel values by specific coefficients.

### Which image formats are supported?

You can upload JPEG, PNG, WebP, GIF, BMP, and TIFF files.

### How do I format the matrix input?

Use the format [[r1,g1,b1],[r2,g2,b2],[r3,g3,b3]], where each row represents the contribution of input channels to the output R, G, and B channels.

### Does this tool support batch processing?

No, this tool is designed for individual image processing to ensure maximum precision for each transformation.

### Which output format should I choose?

PNG is recommended for lossless quality, while JPEG or WebP are better if you need to optimize for smaller file sizes.
