*
* Header file for Device-Independent Bitmap (DIB) API. Provides
* function prototypes and constants for the following functions:
*
* BitmapToDIB() - Creates a DIB from a bitmap
* ChangeBitmapFormat() - Changes a bitmap to a specified DIB format
* ChangeDIBFormat() - Changes a DIB's BPP and/or compression format
* CopyScreenToBitmap() - Copies entire screen to a standard Bitmap
* CopyScreenToDIB() - Copies entire screen to a DIB
* CopyWindowToBitmap() - Copies a window to a standard Bitmap
* CopyWindowToDIB() - Copies a window to a DIB
* CreateDIBPalette() - Creates a palette from a DIB
* CreateDIB() - Creates a new DIB
* DestroyDIB() - Deletes DIB when finished using it
* DIBError() - Displays message box with error message
* DIBHeight() - Gets the DIB height
* DIBNumColors() - Calculates number of colors in the DIB's color table
* DIBToBitmap() - Creates a bitmap from a DIB
* DIBWidth() - Gets the DIB width
* FindDIBBits() - Sets pointer to the DIB bits
* GetSystemPalette() - Gets the current palette
* LoadDIB() - Loads a DIB from a file
* PaintBitmap() - Displays standard bitmap in the specified DC
* PaintDIB() - Displays DIB in the specified DC
* PalEntriesOnDevice() - Gets the number of palette entries
* PaletteSize() - Calculates the buffer size required by a palette
* PrintDIB() - Prints the specified DIB
* PrintScreen() - Prints the entire screen
* PrintWindow() - Prints all or part of a window
* SaveDIB() - Saves the specified dib in a file
*
* See the file DIBAPI.TXT for more information about these functions.
