A lightweight PHP library for efficiently removing EXIF, IPTC, and other metadata from images while preserving quality. Supports JPEG, PNG, and GIF formats.

Features
--------

[](#features)

- Efficient metadata removal with zero quality loss
- Supports multiple image formats and metadata types:
    - JPEG: EXIF and IPTC markers
    - PNG: tEXt, iTXt, and zTXt chunks
    - GIF: XMP and Application Extension blocks
- Privacy-focused: removes sensitive information
- Zero external dependencies (PHP GD only)
- Clean, object-oriented architecture
- Comprehensive test coverage
- PSR-12 compliant

Requirements
------------

[](#requirements)

- PHP 8.0 or higher
- GD extension

Installation
------------

[](#installation)

Install via Composer:

```
composer require metastrip/image
```

Usage
-----

[](#usage)

Basic usage:

```
use MetaStrip\Image\ImageProcessorFactory;

// Create processor instance
$processor = ImageProcessorFactory::create();

// Strip metadata from an image
$processor->stripExifData('/path/to/image.jpg');
```

Advanced usage with specific handlers:

```
use MetaStrip\Image\ImageProcessor;
use MetaStrip\Image\ImageHandler\JpegHandler;
use MetaStrip\Image\ImageHandler\PngHandler;
use MetaStrip\Image\ImageHandler\GifHandler;

// Create processor with specific handlers
$processor = new ImageProcessor([
    IMAGETYPE_JPEG => new JpegHandler(),
    IMAGETYPE_PNG => new PngHandler(),
    IMAGETYPE_GIF => new GifHandler(),
]);

// Process multiple images
$processor->stripExifData('/path/to/image1.jpg');
$processor->stripExifData('/path/to/image2.png');
$processor->stripExifData('/path/to/image3.gif');
```

Development
-----------

[](#development)

### Setup

[](#setup)

1. Clone the repository:

```
git clone https://github.com/metastrip/image.git
cd image
```

2. Install dependencies:

```
composer install
```

### Quality Tools

[](#quality-tools)

We use three main tools to ensure code quality:

1. **PHPUnit** - Testing Framework

    ```
    # Run tests
    composer test

    # Generate coverage report
    composer test:coverage
    ```
2. **PHP\_CodeSniffer** - Code Style

    ```
    # Check coding standards
    composer cs

    # Fix coding standards automatically
    composer cs:fix
    ```
3. **PHPStan** - Static Analysis

    ```
    # Run static analysis
    composer stan
    ```

Run all checks at once:

```
composer check
```

### Continuous Integration

[](#continuous-integration)

Our GitHub Actions workflow automatically runs:

- Tests on PHP 8.0, 8.1, and 8.2
- Code style checks
- Static analysis
- Code coverage reporting
