Yup, that should work just fine like this:
Real16 imgdata2[] =
{ Real16(1), Real16(0), Real16(0), Real16(0.5),
Real16(0), Real16(1), Real16(0), Real16(0.5),
Real16(0), Real16(0), Real16(1), Real16(1),
Real16(.5), Real16(1), Real16(1), Real16(1) };
ImagePtr image = Image::create();
image->set( Image::OSG_RGBA_PF, 2, 2, 1, 1, 1, 0,
reinterpret_cast<UChar8*>(imgdata2),
Image::OSG_FLOAT16_IMAGEDATA );
Hope it helps
Dirk
