+%description
+libultrahdr is an image compression library that uses gain map
+technology to store and distribute HDR images. Conceptually on the
+encoding side, the library accepts SDR and HDR rendition of an image
+and from these a Gain Map (quotient between the two renditions) is
+computed. The library then uses backward compatible means to store the
+base image (SDR), gain map image and some associated metadata. Legacy
+readers that do not support handling the gain map image and/or
+metadata, will display the base image. Readers that support the format
+combine the base image with the gain map and render a high dynamic
+range image on compatible displays.
+
+%description -l pl.UTF-8
+libultrahdr to biblioteka kompresji obrazu, wykorzystująca technikę
+mapy wzmocnień do przechowywania i dystrybucji obrazów HDR.
+Koncepcyjnie po stronie kodowania biblioteka przyjmuje wersje SDR oraz
+HDR obrazu i wylicza z nich mapę wzmocnień (współczynnik między dwoma
+wersjami). Następnie wykorzystując wstecznie zgodne metody zapisuje
+obraz podstawowy (SDR), obraz mapy wzmocnień oraz trochę powiązanych
+metadanych. Starsze czytniki, nie obsługujące obrazu mapy wzmocnień
+i/lub metadanych, wyświetlą obraz podstawowy. Czytniki obsługujące
+format połączą obraz podstawowy z mapą wzmocnień i na zgodnym ekranie
+wyświetlą obraz HDR.
