范例

Example #1 Imagick::queryFonts()

<?php
        $output = '';
        $output .= "Fonts that match 'Helvetica*' are:<br/>";
        $fontList = \Imagick::queryFonts("Helvetica*");
 
        foreach ($fontList as $fontName) {
            $output .= '<li>'. $fontName."</li>";
        }
        return $output;
?>

If you want to create a graphical output of the configured/embedded fonts
function outputFont( $fontName = 'Courier' ) {
  $image = new Imagick();
  $draw = new ImagickDraw();
  $draw->setGravity( Imagick::GRAVITY_CENTER );
  $draw->setFont( $fontName );
  $draw->setFontSize( 12 );
  $draw->setFillColor( 'black' );
  $image->newImage( 300, 20, new ImagickPixel( 'lightblue' ) );
  $image->annotateImage( $draw, 0, 0, 0, $fontName );
  $image->setImageFormat( 'png' );
  $src = 'data: ' . mime_content_type( $image ) . ';base64,' . base64_encode( $image );
  return '<img src="' . $src . '"> ' . $fontName . '<br>';
}
echo '<style>img{vertical-align: middle; margin-bottom: 1px;}</style>';
$fontList = \Imagick::queryFonts( '*' );
foreach ( $fontList as $fontName ) {
  echo outputFont( $fontName );
}
