vipertecpro / image-cropper
A fully native, hand-written freehand image cropper for NativePHP Mobile.
Package info
github.com/vipertecpro/image-cropper
Language:Kotlin
Type:nativephp-plugin
pkg:composer/vipertecpro/image-cropper
Requires
- php: ^8.4
- nativephp/mobile: ^3.0|^4.0
Requires (Dev)
- pestphp/pest: ^3.0
Suggests
- nativephp/mobile-camera: One convenient way to capture or pick an image to feed to ImageCropper::open() — any source of an image file path works.
README
Open a fully native crop & edit screen from PHP — the user drags, pinch-zooms and two-finger-rotates the image behind a crop frame, then you get a real cropped file back. Written in SwiftUI (iOS) and Jetpack Compose (Android), with one simple PHP API and zero third-party native libraries.
Features
- ✂️ Freehand crop — 2D drag, pinch-zoom and two-finger rotate, all at once
- ⭕ Shapes & presets — circle or rectangle; Profile / Square / Portrait / 16:9 / Cover / Banner / Story, switchable live in-screen
- 🎨 Adjust & filter — brightness / contrast / saturation and one-tap filters, baked into the output
- 🧩 Configurable — enable only the modes/tools you need (crop-only, adjust-only, filter-only, …)
- 🌗 Theme-aware — follows the system light / dark theme
- 📦 Zero dependencies — no third-party native libraries, no permissions, no network
- 🍏 🤖 iOS + Android behind one PHP API
Requirements
- PHP 8.4+
- NativePHP Mobile v3 or v4 (
nativephp/mobile: ^3.0|^4.0) - iOS 15+ / Android API 26+
Installation
composer require vipertecpro/image-cropper php artisan vendor:publish --tag=nativephp-plugins-provider # once per app php artisan native:plugin:register vipertecpro/image-cropper php artisan native:plugin:list # verify "ImageCropper" + "ImageCropper.Open" appear php artisan native:run ios # or: android — rebuild so the native code compiles in
Requiring with Composer is not enough — an unregistered plugin does nothing. Always run
native:plugin:registerand confirm withnative:plugin:list.
Usage
Call the facade from a NativeComponent, then handle the result event.
use Native\Mobile\Attributes\On; use Native\Mobile\Edge\NativeComponent; use Vipertecpro\ImageCropper\Events\CropCancelled; use Vipertecpro\ImageCropper\Events\ImageCropped; use Vipertecpro\ImageCropper\Facades\ImageCropper; class Avatar extends NativeComponent { public ?string $photo = null; // an existing image path public ?string $cropped = null; public function crop(): void { ImageCropper::open($this->photo, ['preset' => 'profile']); // circular avatar } #[On(ImageCropped::class)] public function onCropped(string $path): void { $this->cropped = $path; // a brand-new cropped file on disk } #[On(CropCancelled::class)] public function onCancelled(): void { // user backed out — nothing produced } }
Display the result with native:image, e.g. a round avatar:
<native:image :src="$cropped" :fit="2" class="w-[96] h-[96] rounded-full" />
On NativePHP Mobile v3, the
#[On]attribute isn't available — listen for the events with#[OnNative(...)](fromNative\Mobile\Attributes\OnNative) instead. Everything else is identical; the plugin itself is unchanged across v3 and v4.
Getting an image to crop
The plugin's input is a file path to an existing image or an http(s) URL — it does not capture or pick photos itself, so it has no hard dependency on any camera plugin. Any source works: the filesystem, a bundled asset, a picker of your choice, or a remote image.
// Crop an image that lives on your CDN/API — the plugin downloads it // natively (themed loading screen with Cancel), then opens the editor: ImageCropper::open('https://cdn.example.com/avatars/current.jpg', ['preset' => 'profile']);
Only croppable image formats are accepted (jpg, jpeg, png, gif,
webp, bmp, heic, heif, avif): a source with any other extension
throws an InvalidArgumentException immediately, and the native side
additionally verifies the actual content decodes as an image (extensions
can lie) — undecodable content fires CropCancelled, as do download failures.
If you need a picker, nativephp/mobile-camera
is convenient (listed under suggest, not require). Install and register it
separately, then hand its result path to ImageCropper::open().
API
ImageCropper::open(string $pathOrUrl, array $options = []): void;
The crop experience is configurable so one plugin covers many use cases.
| Option | Values | Default |
|---|---|---|
preset |
profile (circle), square, portrait, landscape, cover, banner, story |
— |
shape |
circle | rect (overrides the preset) |
rect |
aspectRatio |
width / height, e.g. 16/9 (overrides the preset) |
1.0 |
tools |
any of ['zoom', 'rotate'] — which crop fine-tune rulers show |
both |
modes |
any of ['crop', 'adjust', 'filter'] — editor modes offered; opens on the first |
all three |
presets |
preset keys offered in the in-screen selector; [] hides it & locks the crop |
all |
outputSize |
longest edge of the output, px | 1024 |
theme |
hex colors to match YOUR app — background, text, accent (Done), highlight (active states); omitted keys keep the system-adaptive default |
system light/dark |
id |
correlation id echoed back on the event | null |
ImageCropper::open($path, ['preset' => 'profile']); // round avatar ImageCropper::open($path, ['preset' => 'cover']); // wide banner ImageCropper::open($path, ['shape' => 'rect', 'aspectRatio' => 3.0, 'tools' => ['zoom']]); // A bare, locked cropper — no preset switching, no colour editing: ImageCropper::open($path, ['preset' => 'profile', 'presets' => [], 'modes' => ['crop']]); // No crop at all — operate on the WHOLE image and export the full photo: ImageCropper::open($path, ['modes' => ['adjust']]); // colour adjustments only ImageCropper::open($path, ['modes' => ['filter']]); // one-tap filters only // Render the editor in YOUR app's theme (identical on iOS and Android): ImageCropper::open($path, [ 'preset' => 'profile', 'theme' => [ 'background' => '#121417', // editor background 'text' => '#FFFFFF', // labels & inactive icons 'accent' => '#C2410C', // the Done button 'highlight' => '#C2410C', // selected preset/filter, ruler value & fill ], ]);
When modes omits crop, the editor drops the crop frame entirely, shows the
whole image, and exports the full photo (longest edge = outputSize) with the
colour baked in.
Events
| Event | Payload | Fired when |
|---|---|---|
Vipertecpro\ImageCropper\Events\ImageCropped |
string $path, ?string $id |
The user confirms — $path is the new cropped file. |
Vipertecpro\ImageCropper\Events\CropCancelled |
?string $id |
The user cancels, or the source couldn't be read. |
Pass an id option when several crops could be in flight, to correlate the event.
Legacy web-view apps
A JS bridge is shipped at resources/js/imageCropper.js. Because the result is
async, subscribe to the native events with the #nativephp On() helper — see
the file header for an example.
Demo app
A full sample NativePHP app showcases the plugin with five ready-made examples
(full studio, locked profile avatar, locked cover, adjust-only, filter-only) —
each a tiny NativeComponent you can copy from:
👉 vipertecpro/supernativephp-image-manipulation
git clone https://github.com/vipertecpro/supernativephp-image-manipulation cd supernativephp-image-manipulation composer install php artisan native:run ios # or: android
