Indeed, that's an *enum value*, not a #define !

typedef enum LTIColorSpace
{
[...]
  LTI_COLORSPACE_GRAYSCALEA = LTI_COLORSPACE_GRAYSCALE | 
LTI_COLORSPACE_MASK_ALPHA,
  LTI_COLORSPACE_GRAYSCALEA_PM = LTI_COLORSPACE_GRAYSCALEA | 
LTI_COLORSPACE_MASK_ALPHA_PRE_MULTIPLIED,


I interpreted your "Looks good" as "applied and successfully tested"...

I do have SDK 8 indeed, so I replaced the conditional test with:

#if defined(LTI_SDK_MAJOR) && LTI_SDK_MAJOR >= 8
