Customizing Header Bitmap for Modern Skin Interface

Hello,

My question is primarily concerned with the NSIS Modern User interface.

I can get the custom header bitmap to show up using

!define MUI_HEADERIMAGE
!define MUI_HEADERIMAGE_BITMAP "C:\...\logo.bmp"

But the bitmap image does not cover the entire header field. Is there any way in which I can set the header bitmap as a wallpaper style image (i.e. the image lies underneath whilst the text is written on top)?

On the same note, is it possible to have a custom wallpaper for the entire installation instead of having predefined fields of set size?

Regards

You can edit Contrib\UIs\modern.exe with Resource Hacker and tell the MUI to use it with the MUI_UI define.
