SDL_GetSurfaceProperties - Get the properties associated with a surface.

       This function is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10                        SDL_GetSurfaceProperties(3)

       The following properties are understood by SDL:

       • SDL_PROP_SURFACE_SDR_WHITE_POINT_FLOAT :
         for HDR10 and floating point surfaces, this defines the value of 100%
         diffuse white, with higher values being displayed in the High Dynamic
         Range headroom. This defaults to 203 for HDR10 surfaces and 1.0 for
         floating point surfaces.

       • SDL_PROP_SURFACE_HDR_HEADROOM_FLOAT :
         for HDR10 and floating point surfaces, this defines the maximum dynamic
         range used by the content, in terms of the SDR white point. This defaults
         to 0.0, which disables tone mapping.

       • SDL_PROP_SURFACE_TONEMAP_OPERATOR_STRING :
         the tone mapping operator used when compressing from a surface with high
         dynamic range to another with lower dynamic range. Currently this
         supports "chrome", which uses the same tone mapping that Chrome uses for
         HDR content, the form "*=N", where N is a floating point scale factor
         applied in linear space, and "none", which disables tone mapping. This
         defaults to "chrome".

       • SDL_PROP_SURFACE_HOTSPOT_X_NUMBER :
         the hotspot pixel offset from the left edge of the image, if this surface
         is being used as a cursor.

       • SDL_PROP_SURFACE_HOTSPOT_Y_NUMBER :
         the hotspot pixel offset from the top edge of the image, if this surface
         is being used as a cursor.
