Re: [ros-dev] [ros-diffs] [jimtabor] 37766: - Sync in rev 37720: Magnus Olsen, add GdiGetBitmapBitsSize is a new api from windows xp sp3, the code was tested in vs2003.

[Aleksey Bragin]

Instead of copying the whole formula, it could be done as
ULONG Height;
if (lpbmi->bmiHeader.biHeight >=0 )
     Height = lpbmi->bmiHeader.biHeight;
else
     Height = -lpbmi->bmiHeader.biHeight;

retSize = Height * ((lpbmi->bmiHeader.biWidth *
                           lpbmi->bmiHeader.biPlanes * lpbmi- 
>  bmiHeader.biBitCount + 31) & -32) / 8; 
Also comments contain typos
/* Make height postiive if it negitve then calc the bits Size and  
align it*/
postiive, negitive


WBR,
Aleksey.
