CalcBufferSize

[tigerssj]

hello! follow is code snippet in the file applications/_plugins/common/texture_utils.cpp, in the function
CMP_DWORD CalcBufferSize(CMP_FORMAT format, CMP_DWORD dwWidth, CMP_DWORD dwHeight, CMP_DWORD dwPitch, CMP_BYTE nBlockWidth, CMP_BYTE nBlockHeight);

why the channel count of the formats CMP_FORMAT_RG_16 and CMP_FORMAT_RG_16F is 4? I think it has 2 channels

case CMP_FORMAT_RG_16:
case CMP_FORMAT_RG_16F:
return ((dwPitch) ? (dwPitch * dwHeight) : (dwWidth * 2 * sizeof(CMP_WORD) * dwHeight));

and the formats CMP_FORMAT_R_16 and CMP_FORMAT_R_16F has 1 channel, so:
return ((dwPitch) ? (dwPitch * dwHeight) : (dwWidth * 1* sizeof(CMP_WORD) * dwHeight));

Am I wrong?
Why isn't it the case here?

here is the source codes:
case CMP_FORMAT_ARGB_16:
case CMP_FORMAT_ABGR_16:
case CMP_FORMAT_RGBA_16:
case CMP_FORMAT_BGRA_16:
case CMP_FORMAT_ARGB_16F:
case CMP_FORMAT_ABGR_16F:
case CMP_FORMAT_RGBA_16F:
case CMP_FORMAT_BGRA_16F:
return ((dwPitch) ? (dwPitch * dwHeight) : (dwWidth * 4 * sizeof(CMP_WORD) * dwHeight));

case CMP_FORMAT_RG_16:
case CMP_FORMAT_RG_16F:
    return ((dwPitch) ? (dwPitch * dwHeight) : (dwWidth * 4 * sizeof(CMP_WORD) * dwHeight));

case CMP_FORMAT_R_16:
case CMP_FORMAT_R_16F:
    return ((dwPitch) ? (dwPitch * dwHeight) : (dwWidth * 4 * sizeof(CMP_WORD) * dwHeight));
