PHPで文字を画像にするやつ

Posted at

ちょっと、そういうのが必要になったので。(WEBGLで日本語フォントが通らないとか・・・)

im.php?str=こんにちは,世界にアクセスすると、カンマ区切りで改行して、こんな画像を生成します。

<?php
if( isset($_GET["str"]) ){
    $points = explode(",",$_GET["str"]);
}else{
    $str = ["Hello","World"];
}

$im = imagecreatetruecolor(400,600);
imagefilledrectangle($im, 0, 0, 599, 399, 0x101010);
$font = '/font/NotoSansCJKjp-Regular.otf';
$y = 30;
foreach($points as $point){
    imagettftext($im, 20, 0, 0, $y, 0xffffff, $font, $point);
    $y = $y + 30;
}
header('Content-Type: image/png;');
imagepng($im);
imagedestroy($im);
