Ultra HDR is a true HDR image format, and is backcompatible. libultrahdr is the reference codec for the Ultra HDR format. The codecs that support the format can render the HDR intent of the image on HDR displays; other codecs can still decode and display the SDR intent of the image.

Ambiguous wording in ultrahdr_app help #213

Closed pmonck closed 1 month ago

pmonck commented 1 month ago

I feel the description of ultrahdr_app's -M option is unclear.

I propose that

"-M enable / disable multi channel gain map, optional. [0:no (default), 1:yes]."

be replaced with

"-M enable multi channel gain map, optional. [0:no (default), 1:yes]."

or

"-M enable / disable multi channel gain map, optional. [0:disable (default), 1:enable]."

@pmonck @DichenZhang1 the sample app is updated accordingly. This bug can be marked for closure.
