Creates a compatible bitmap (DDB) from a DIB and, optionally, sets the bitmap bits
#include <WinAPIGdi.au3>
_WinAPI_CreateDIBitmap ( $hDC, $tBITMAPINFO, $iUsage [, $pBits = 0] )
| $hDC | Handle to a device context. |
| $tBITMAPINFO | $tagBITMAPINFO structure that specifies various attributes of the DIB, including the bitmap dimensions and colors. Note that a positive value for the height indicates a bottom-up DIB while a negative value for the height indicates a top-down DIB. |
| $iUsage | The type of colors used. This parameter must be one of the following values: $DIB_PAL_COLORS $DIB_RGB_COLORS |
| $pBits | [optional] A pointer to an array of bytes containing the initial bitmap data. |
| Success: | the handle to the compatible bitmap that will be whatever bit depth a reference DC is. |
| Failure: | 0. |
When you no longer need the bitmap, call the _WinAPI_DeleteObject() function to delete it.
