#Usage

#Filament Version Compatibility

This package supports both Filament 3.0+ and Filament 4.0+ with automatic compatibility detection.

#Filament 3.0+ (Legacy)

// Forms, Actions & Tables
use SolutionForest\FilamentPanzoom\Components\PanZoom;
 
public static function form(Form $form): Form
{
    return $form->schema([
        PanZoom::make('image_preview')
            ->imageUrl(fn ($record) => $record?->image_url)
            ->label('Image Preview')
            ->columnSpanFull(),
    ]);
}
 
// Infolists
use SolutionForest\FilamentPanzoom\Infolists\Components\PanZoomEntry;
 
public function infolist(Infolist $infolist): Infolist
{
    return $infolist->schema([
        PanZoomEntry::make('image_preview')
            ->imageUrl(fn ($record) => $record?->image_url)
            ->label('Image Preview'),
    ]);
}

#Filament 4.0+ (Current)

// Forms - Uses Schemas
use SolutionForest\FilamentPanzoom\Components\PanZoom;
 
public static function configure(Schema $schema): Schema
{
    return $schema->components([
        PanZoom::make('image_preview')
            ->imageUrl(fn ($record) => $record?->image_url),
        // Note: label() and columnSpanFull() methods not available in 4.0+
    ]);
}
 
// Infolists - Uses Schemas
use SolutionForest\FilamentPanzoom\Infolists\Components\PanZoomEntry;
 
public static function configure(Schema $schema): Schema
{
    return $schema->components([
        PanZoomEntry::make('image_preview')
            ->imageUrl(fn ($record) => $record?->image_url),
    ]);
}

#Configurable Double-Click Zoom

You can customize the double-click zoom level for each component. Double-clicking again will return the image to the original fit-to-container view:

// Filament 3.0+ Forms
PanZoom::make('image_preview')
    ->imageUrl(fn ($record) => $record?->image_url)
    ->doubleClickZoomLevel(2.5)  // Zoom to 2.5x instead of default 3x
    ->label('Image Preview');
 
// Filament 4.0+ Forms
PanZoom::make('image_preview')
    ->imageUrl(fn ($record) => $record?->image_url)
    ->doubleClickZoomLevel(4.0)  // Zoom to 4x for more detail
    ->columnSpanFull();
 
// Infolists (both 3.0+ and 4.0+)
PanZoomEntry::make('image_preview')
    ->imageUrl(fn ($record) => $record?->image_url)
    ->doubleClickZoomLevel(2.0)  // Zoom to 2x
    ->imageId(fn ($record) => 'image-' . $record->id);

Available Zoom Levels:

• Range: 0.5x to 5.0x
• Default: 3.0x (good balance for detail viewing)
• Common values:
  • 2.0 - Moderate zoom
  • 2.5 - Balanced zoom
  • 3.0 - Default (detailed view)
  • 4.0 - High zoom
  • 5.0 - Maximum zoom

#In Blade Views

You can use the component directly in any Blade view (works in both 3.0+ and 4.0+):

@include('filament-panzoom::filament-panzoom', [
    'imageUrl' => 'https://example.com/image.jpg',
    'imageId' => 'unique-image-id',
    'doubleClickZoomLevel' => 2.5  // Custom zoom level (double-click again to return to fit)
])

#Component Selection Guide

⚠️ Important: Choose the correct component for your context!

Why two components? Filament has separate component hierarchies for Forms and Infolists. Using the wrong one will cause a TypeError.

#Key Differences: Filament 3.0+ vs 4.0+

#Usage Examples

#Filament 3.0+ Examples

In Forms:

public static function form(Form $form): Form
{
    return $form->schema([
        PanZoom::make('image_preview')
            ->imageUrl(fn ($record) => $record?->image_url)
            ->label('Image Preview')
            ->columnSpanFull(),
    ]);
}

In Infolists:

use SolutionForest\FilamentPanzoom\Infolists\Components\PanZoomEntry;
 
public function infolist(Infolist $infolist): Infolist
{
    return $infolist->schema([
        PanZoomEntry::make('receipt_image')
            ->imageUrl(fn ($record) => asset('storage/' . $record->image_path))
            ->label('Receipt Image')
            ->imageId(fn ($record) => 'receipt-' . $record->id),
    ]);
}

In Table Actions:

public static function table(Table $table): Table
{
    return $table->actions([
        Action::make('viewImage')
            ->form([
                PanZoom::make('image_viewer')
                    ->imageUrl(fn ($record) => $record->image_url)
                    ->label('Image Viewer'),
            ])
    ]);
}

In Custom Pages:

protected function getFormSchema(): array
{
    return [
        PanZoom::make('document_viewer')
            ->imageUrl($this->imageUrl)
            ->label('Document Viewer')
            ->columnSpanFull(),
    ];
}

#Filament 4.0+ Examples

In Forms (Schemas):

public static function configure(Schema $schema): Schema
{
    return $schema->components([
        PanZoom::make('image_preview')
            ->imageUrl(fn ($record) => $record?->image_url),
        // Note: label() and columnSpanFull() methods not available in 4.0+
    ]);
}

In Infolists (Schemas):

use SolutionForest\FilamentPanzoom\Infolists\Components\PanZoomEntry;
 
public static function configure(Schema $schema): Schema
{
    return $schema->components([
        PanZoomEntry::make('receipt_image')
            ->imageUrl(fn ($record) => asset('storage/' . $record->image_path))
            ->imageId(fn ($record) => 'receipt-' . $record->id),
    ]);
}

        Action::make('viewImage')
            ->form([
                PanZoom::make('image_viewer')
                    ->imageUrl(fn ($record) => $record->image_url),
            ])
    ]);
}

In Custom Pages:

protected function getFormSchema(): array
{
    return [
        PanZoom::make('document_viewer')

    ];
}

#Troubleshooting

#Common Issues

TypeError: Argument #1 ($component) must be of type Filament\Infolists\Components\Component

• ❌ You're using PanZoom in an Infolist
• ✅ Use PanZoomEntry for Infolists instead

TypeError: Argument #1 ($component) must be of type Filament\Forms\Components\Component

• ❌ You're using PanZoomEntry in a Form/Action
• ✅ Use PanZoom for Forms/Actions instead

Fatal Error: Class was composed with trait conflicts

• ✅ Fixed in v1.2.1+ - update your package

Method not found: label() or columnSpanFull() in Filament 4.0+

• ❌ These methods aren't available in Filament 4.0+ Schemas
• ✅ Remove these method calls or use Filament 3.0+ syntax

Undefined type 'Filament\Schemas\Components\Component'

• ❌ Linter error in Filament 3.0+ environment
• ✅ This is expected - the package uses runtime detection for compatibility

#Version-Specific Issues

#Filament 3.0+

• ✅ All methods available (label(), columnSpanFull(), etc.)
• ✅ Traditional Forms/Infolists structure

#Filament 4.0+

• ⚠️ Limited methods available (Schemas-based)
• ⚠️ Different structure (configure(Schema $schema))
• ✅ Automatic compatibility detection

#Quick Reference

#Browser Support

• Chrome 70+
