https://ru.wikipedia.org/wiki/TIFF
TIFF (англ. Tagged Image File Format) — формат хранения растровых графических изображений. TIFF стал популярным форматом для хранения изображений с большой глубиной цвета. Он используется при сканировании, отправке факсов, распознавании текста, в полиграфии, широко поддерживается графическими приложениями. TIFF был выбран в качестве основного графического формата операционной системы NeXTSTEP и из неё поддержка этого формата перешла в Mac OS X. Формат был разработан Aldus Corporation. Компания — владелец спецификаций — Aldus Corporation — впоследствии объединилась с Adobe Systems, владеющей в настоящее время авторским правом на эти спецификации[3].
