BITMAP info  Overview  Group

The BITMAP structure defines the type, width, height, color format, and bit values of a bitmap.

typedef struct tagBITMAP {  // bm 

   LONG   bmType; 

   LONG   bmWidth; 

   LONG   bmHeight; 

   LONG   bmWidthBytes; 

   WORD   bmPlanes; 

   WORD   bmBitsPixel; 

   LPVOID bmBits; 

} BITMAP; 

 

Members

bmType
Specifies the bitmap type. This member must be zero.
bmWidth
Specifies the width, in pixels, of the bitmap. The width must be greater than zero.
bmHeight
Specifies the height, in pixels, of the bitmap. The height must be greater than zero.
bmWidthBytes
Specifies the number of bytes in each scan line. This value must be divisible by 2, because Windows assumes that the bit values of a bitmap form an array that is word aligned.
bmPlanes
Specifies the count of color planes.
bmBitsPixel
Specifies the number of bits required to indicate the color of a pixel.
bmBits
Points to the location of the bit values for the bitmap. The bmBits member must be a long pointer to an array of character (1-byte) values.

Remarks

The bitmap formats currently used are monochrome and color. The monochrome bitmap uses a one-bit, one-plane format. Each scan is a multiple of 32 bits.

Scans are organized as follows for a monochrome bitmap of height n:

    Scan 0 

    Scan 1 

    . 

    . 

    . 

    Scan n-2 

    Scan n-1 

 

The pixels on a monochrome device are either black or white. If the corresponding bit in the bitmap is 1, the pixel is set to the foreground color; if the corresponding bit in the bitmap is zero, the pixel is set to the background color.

All devices that have the RC_BITBLT device capability support bitmaps. For more information, see GetDeviceCaps.

Each device has a unique color format. To transfer a bitmap from one device to another, use the GetDIBits and SetDIBits functions.
