use Ycdev\PaperSize;

// Get A4 dimensions in pixels (default 300 DPI)
$dimensions = PaperSize::px(PaperSize::A4);
// Result: [2480, 3508]

// Get A4 dimensions in centimeters
$dimensions = PaperSize::cm(PaperSize::A4);
// Result: [21.0, 29.7]

// Get A4 dimensions in inches
$dimensions = PaperSize::in(PaperSize::A4);
// Result: [8.27, 11.69]

use Ycdev\PaperSize;

// Create a GD image with A4 dimensions

use Ycdev\PaperSize;

// Get the aspect ratio of A4 format

// Result: 1.4142

use Ycdev\PaperSize;

// Convert A4 format to landscape
$landscape = PaperSize::landscape(PaperSize::A4);
// Result: [297, 210]

// Example: populate a <select>
