Return a flag that you can pass to the ‘imagingmode’ parameter of
Screen(‘OpenWindow’) in order to request support for internal
framebuffers that store color information with 32 bits per color
component in floating point format.
If requested and supported by the graphics hardware, Psychtoolbox will
configure itself to store and process all color information as 32 bit
floating point numbers.
FIXME: More info…
This is part of the Psychtoolbox imaging pipeline and only works on modern
graphics hardware, e.g., ATI Radeon X1000 and later, NVidia Geforce-6000
and later. Check the www.psychtoolbox.org Wiki for graphics hardware
recommendations and for a description of PTB’s image processing
capabilities.
