все замечательно кроме одного - в gif файле есть информация о времени отображения кадра
а данное решение не считывает значение задержки, оно просто считывает кадры и выдает их на экран с частотой указанной в таймере.
Можно как-то считывать данные отображения кадра из GIF и добавить их в это решение или может есть друге решения для отображения GIF?
