Image Resizer

Downscale images using native platform APIs — ImageIO on iOS and BitmapFactory on Android — from a NativePHP Mobile app.

Features

• Resize images to a maximum side length while preserving aspect ratio
• No upscaling — only downscales
• Automatic EXIF orientation correction on both platforms
• Output always written as JPEG
• Memory-efficient: iOS streams from disk via thumbnail API; Android uses inSampleSize on decode

Installation

composer require coyotito/image-resizer

Register the plugin in your NativeServiceProvider:

public function plugins(): array
{
    return [
        \Coyotito\ImageResizer\ImageResizerServiceProvider::class,
    ];
}

Usage

use Coyotito\ImageResizer\Facades\ImageResizer;

$ok = ImageResizer::resize(
    sourcePath: '/abs/path/to/source.jpg',
    targetPath: '/abs/path/to/target.jpg',
    maxSide: 1024,  // longest side cap; preserves aspect ratio
    quality: 80,    // JPEG quality, 0–100
);

Returns true on success, false on failure. The target is always written as JPEG.
