Creates a bitmap compatible with the device and fills it the specified color
#include <WinAPIGdi.au3>
_WinAPI_CreateCompatibleBitmapEx ( $hDC, $iWidth, $iHeight, $iRGB )
| $hDC | Handle to a device context. | 
| $iWidth | The bitmap width, in pixels. | 
| $iHeight | The bitmap height, in pixels. | 
| $iRGB | The bitmap color, in RGB. | 
| Success: | Handle to the compatible solid bitmap (DDB). | 
| Failure: | 0 and sets the @error flag to non-zero. | 
The color format of the bitmap created by the _WinAPI_CreateCompatibleBitmapEx() function matches the color format of the device identified by the $hDC parameter.
This bitmap can be selected into any memory device context that is compatible with the original device.
When you no longer need the bitmap, call the _WinAPI_DeleteObject() function to delete it.
