BITMAPINFOHEADER2

Bit-map 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.

Type

typedef struct _BITMAPINFOHEADER2 {
 ULONG   cbFix;          /* Length of structure. */
 ULONG   cx;             /* Bit-map width in pels. */
 ULONG   cy;             /* Bit-map 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 bit-map 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;
