22 Important information:
24 * Current Windows versions support two different DIB structures:
26 - BITMAPCOREINFO / BITMAPCOREHEADER (legacy structures; used in OS/2)
27 - BITMAPINFO / BITMAPINFOHEADER
29 Most Windows API functions taking a BITMAPINFO* / BITMAPINFOHEADER* also
30 accept the old "core" structures, and so must WINE.
31 You can distinguish them by looking at the first member (bcSize/biSize),
32 or use the internal function DIB_GetBitmapInfo.
35 * The palettes are stored in different formats:
37 - BITMAPCOREINFO: Array of RGBTRIPLE
38 - BITMAPINFO: Array of RGBQUAD
41 * There are even more DIB headers, but they all extend BITMAPINFOHEADER:
43 - BITMAPV4HEADER: Introduced in Windows 95 / NT 4.0
44 - BITMAPV5HEADER: Introduced in Windows 98 / 2000
46 If biCompression is BI_BITFIELDS, the color masks are at the same position
47 in all the headers (they start at bmiColors of BITMAPINFOHEADER), because
48 the new headers have structure members for the masks.
51 * You should never access the color table using the bmiColors member,
52 because the passed structure may have one of the extended headers
53 mentioned above. Use this to calculate the location:
56 void* colorPtr = (LPBYTE) info + (WORD) info->bmiHeader.biSize;
