On the AROS-Dev mailing list I've made a proposal to extend the AmigaOS (Clone) API with support - i.e. a corresponding PIX/PBAFMT - for 48/64 bit bitmaps.

I'd appreciate everyone interested to participate in the discussion thread there - it would be important to sync this API extension among AOS4/MOS and AROS anyway.

As a short summary - the idea is to add the following:

16:16:16 RGB (48 bit)
16:16:16: RGBA (64 bit)

in addition to the conventional:

8:8:8 RGB (24 bit)
8:8:8:8 RGBA (32 bit)

This is supported already today by PNG and TIFF and required for professional image processing / video editing systems - even though you won't find any conventional framebuffers which directly support it.

Still it would be helpful, if not the application but the OS would take care how to render/convert this "high data range" bitmap data.

Well, would be just another pixel formart for Bitmaps and PixelArrays. I dont see where the API needs to be extended.
