Bitmap information header structure.

Each bit plane logically contains (cx * cy * cBitCount) bits, although the actual length can be greater because of padding.

Note: Many functions can accept either this structure or the BITMAPINFOHEADER structure. Where possible, use BITMAPINFOHEADER2.

typedef struct _BITMAPINFOHEADER2 {
  ULONG      cbFix;            /*  Length of structure. */
  ULONG      cx;               /*  Bitmap width in pels. */
  ULONG      cy;               /*  Bitmap height in pels. */
  USHORT     cPlanes;          /*  Number of bit planes. */
  USHORT     cBitCount;        /*  Number of bits per pel within a plane. */
  ULONG      ulCompression;    /*  Compression scheme used to store the bit map. */
  ULONG      cbImage;          /*  Length of bitmap storage data, in bytes. */
  ULONG      cxResolution;     /*  Horizontal component of the resolution of target device. */
  ULONG      cyResolution;     /*  Vertical component of the resolution of target device. */
  ULONG      cclrUsed;         /*  Number of color indexes used. */
  ULONG      cclrImportant;    /*  Minimum number of color indexes for satisfactory appearance of the bit map. */
  USHORT     usUnits;          /*  Units of measure. */
  USHORT     usReserved;       /*  Reserved. */
  USHORT     usRecording;      /*  Recording algorithm. */
  USHORT     usRendering;      /*  Halftoning algorithm. */
  ULONG      cSize1;           /*  Size value 1. */
  ULONG      cSize2;           /*  Size value 2. */
  ULONG      ulColorEncoding;  /*  Color encoding. */
  ULONG      ulIdentifier;     /*  Reserved for application use. */
} BITMAPINFOHEADER2;

typedef   BITMAPINFOHEADER2   * PBITMAPINFOHEADER2 ;
