м хранит подписи (используяsignaturepad в моей базе данныхColdfusion/MySQL 5.0.88 и хотел бы вывести подпись I 'беру на PDF, который ям генерации сfpdf, Однако я не могу заставить его работать ...

Подписи хранятся так:

В siganturepad есть пользовательская функция (подпись к изображению), чтобы преобразовать вышеуказанное обратно в изображение. Вот так:

Но если я попробую это на моей странице fpdf, вся страница будет разрываться (наверное, потому что я хочу встроить изображение в ячейку, а не выводить только изображение в браузер), и я получу следующее:

Если я'Я делаю это:

if( strlen($unterschrift) > 0){
    $img = sigJsonToImage( $unterschrift );
};

и попробуйте вывести:

if ( $imgProceed == "true" ){
    $pdf->imagepng($img);
} else {
    $pdf->Cell(50,4,'',0,1);
}

все яЯ получаю это:

`Call to undefined method PDF::imagepng() `/ `strpos() expects parameter 1 to be string, resource` 

Может кто-нибудь объяснить мне, что яя делаю неправильно или что мне нужно сделать, чтобы включить изображение в ячейку в fpdf? Я'м невежественный

Спасибо!
