Stdout Streaming

LaraSVG can output conversion results directly to stdout, which is useful for streaming binary data in HTTP responses without writing temporary files.

Basic Usage

$binary = SvgConverter::open(resource_path('svg/logo.svg'))
    ->setDimensions(512, 512)
    ->toStdout('png');

The toStdout() method returns the raw binary data as a string.

HTTP Response Streaming

Serve a converted image directly from a Laravel route:

use Laratusk\Larasvg\Facades\SvgConverter;

Route::get('/logo.png', function () {
    $binary = SvgConverter::open(storage_path('app/logo.svg'))
        ->setDimensions(512, 512)
        ->toStdout('png');

    return response($binary)
        ->header('Content-Type', 'image/png')
        ->header('Cache-Control', 'public, max-age=86400');
});

Dynamic Conversion Endpoint

Route::get('/convert/{format}', function (string $format) {
    $binary = SvgConverter::using('inkscape')
        ->open(storage_path('app/design.svg'))
        ->toStdout($format);

    $contentTypes = [
        'png' => 'image/png',
        'pdf' => 'application/pdf',
    ];

    return response($binary)
        ->header('Content-Type', $contentTypes[$format] ?? 'application/octet-stream');
});

How It Works

• Resvg uses the -c flag to output to stdout
• Inkscape uses --export-filename=- to output to stdout

Both approaches are handled automatically — just call toStdout().
