GetBitmapBits Overview Group

The GetBitmapBits function copies the bitmap bits of a specified bitmap into a buffer.

The GetBitmapBits function is obsolete. This function is provided for compatibility with 16-bit versions of Windows. Win32-based applications should use the GetDIBits function.

LONG GetBitmapBits (

HBITMAP hbmp,

// handle to bitmap

LONG cbBuffer,

// number of bytes to copy

LPVOID lpvBits

// pointer to buffer to receive bits

);

Parameters

hbmp: Handle to the bitmap of interest.
cbBuffer: Specifies the number of bytes to copy from the bitmap into the buffer.
lpvBits: Pointer to a buffer to receive the bitmap bits. The bits are stored as an array of byte values.

Return Values

If the function succeeds, the return value is the number of bytes copied to the buffer.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

HBITMAP hbmp,	// handle to bitmap
LONG cbBuffer,	// number of bytes to copy
LPVOID lpvBits	// pointer to buffer to receive bits
);
