Mimics Windows BITMAPINFOHEADER structure. For details search for "BITMAPINFOHEADER" at http://msdn.microsoft.com/default.asp Windows sizeof(BITMAPINFOHEADER) = 80.
unsigned short ON_WindowsBITMAPINFOHEADER::biBitCount |
WORD = bits per pixel (0,1,4,8,16,24,32 are valid) 1 See http://msdn.microsoft.com/default.asp
4 See http://msdn.microsoft.com/default.asp
8 The bitmap has a maximum of 256 colors, and the bmiColors member contains up to 256 entries. In this case, each byte in the array represents a single pixel. 16 See http://msdn.microsoft.com/default.asp
24 If biClrUsed=0 and biCompression=BI_RGB(0), then each 3-byte triplet in the bitmap array represents the relative intensities of blue, green, and red, respectively, for a pixel. For other possibilities, see http://msdn.microsoft.com/default.asp
32 If biClrUsed=0 and biCompression=BI_RGB(0), then each 4-byte DWORD in the bitmap array represents the relative intensities of blue, green, and red, respectively, for a pixel. The high byte in each DWORD is not used.
If biClrUsed=3, biCompression=BITFIELDS(3), biColors[0] = red mask (0x00FF0000), biColors[1] = green mask (0x0000FF00), and biColors[2] = blue mask (0x000000FF), then these masks are used with each 4-byte DWORD in the bitmap array to determine the pixel's relative intensities. ///<

unsigned int ON_WindowsBITMAPINFOHEADER::biClrImportant |
DWORD.
unsigned int ON_WindowsBITMAPINFOHEADER::biClrUsed |
DWORD = 0 or true length of bmiColors[] array. If 0, then the value of biBitCount determines the length of the bmiColors[] array.
unsigned int ON_WindowsBITMAPINFOHEADER::biCompression |
DWORD Currently, Windows defines the following types of compression. =0 BI_RGB (no compression) =1 BI_RLE8 (run length encoded used for 8 bpp) =2 BI_RLE4 (run length encoded used for 4 bpp) =3 BI_BITFIELDS Specifies that the bitmap is not compressed and that the color table consists of three DWORD color masks that specify the red, green, and blue components, respectively, of each pixel. This is valid when used with 16- and 32-bit-per-pixel bitmaps. =4 BI_JPEG (not supported in Win 95/NT4)
int ON_WindowsBITMAPINFOHEADER::biHeight |
LONG = height (in pixels) of (decompressed) bitmap >0 means it's a bottom-up bitmap with origin in the lower left corner. <0 means it's a top-down bitmap with origin in the upper left corner.
unsigned short ON_WindowsBITMAPINFOHEADER::biPlanes |
WORD = number of planes (always 1 in current Windows versions)
unsigned int ON_WindowsBITMAPINFOHEADER::biSize |
DWORD = sizeof(BITMAPINFOHEADER)
unsigned int ON_WindowsBITMAPINFOHEADER::biSizeImage |
DWORD = bytes in image.
int ON_WindowsBITMAPINFOHEADER::biWidth |
LONG = width (in pixels) of (decompressed) bitmap.
int ON_WindowsBITMAPINFOHEADER::biXPelsPerMeter |
LONG.
int ON_WindowsBITMAPINFOHEADER::biYPelsPerMeter |
LONG.
