PHP ReadShort Examples

Example #1

File: makefont.php Project: richarrieta/MyTeam

function CheckTTF($file)
{
	//Check if font license allows embedding
	$f = fopen($file, 'rb');
	if (!$f) {
		die('Error: unable to open ' . $file);
	}
	//Extract number of tables
	fseek($f, 4, SEEK_CUR);
	$nb = ReadShort($f);
	fseek($f, 6, SEEK_CUR);
	//Seek OS/2 table
	$found = false;
	for ($i = 0; $i < $nb; $i++) {
		if (fread($f, 4) == 'OS/2') {
			$found = true;
			break;
		}
		fseek($f, 12, SEEK_CUR);
	}
	if (!$found) {
		fclose($f);

		return;
	}
	fseek($f, 4, SEEK_CUR);
	$offset = ReadLong($f);
	fseek($f, $offset, SEEK_SET);
	//Extract fsType flags
	fseek($f, 8, SEEK_CUR);
	$fsType = ReadShort($f);

	fclose($f);
	if ($rl AND (!$pp) AND (!$e)) {
		print "Warning: font license does not allow embedding\n";
