BgImage.DLL - NSIS extension DLL
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Displays an image behind the NSIS window.
Can also play WAVs.
Note
~~~~
All but the last used function (which should be Destroy) must use /NOUNLOAD so the image window won't be destroyed before it should. Therefore, this DLL requires NSIS 2.0a7 and above.
Available functions
~~~~~~~~~~~~~~
Init path_to_bitmap [/FILLSCREEN]
Create a new image window
Use /FILLSCREEN to make the image fill the screen
Do not use in .onInit!
SetImage path_to_bitmap [/FILLSCREEN]
Sets a new image to the current timage window
Use /FILLSCREEN to make the image fill the screen
Do not use in .onInit!
Destroy
Destroys the current image window
Sound path_to_wav [/WAIT]
Plays a wave file
Use /WAIT to wait for the sound to finish playing
