これ解析頼みます
int colorAlloc = 256 * sizeof(RGBQUAD); // size of color tables
int bitsAlloc = infoHeader.biSize + colorAlloc;//+ infoHeader.biSizeImage;
pMapBits = (LPBITMAPINFO)new BYTE[bitsAlloc];
memset(pMapBits,80,bitsAlloc*sizeof(BYTE));
pMapBits->bmiHeader = infoHeader;
LPSTR pColor = ((LPSTR)pMapBits + (WORD)(pMapBits->bmiHeader.biSize));
for (i = 0; i < 256; i++)
((WORD*)pColor)[i] = i;
