Full screen background image in Inno Setup

问题:

How to give our setup a background full screen image in Inno Setup compiler.

Like this picture below.

Do not do that. It's against Windows design guidelines.

Anyway, if you have to, enable legacy full screen installer mode using the WindowVisible=yes directive and then modify the (now visible) background window via MainForm global variable of type TMainForm.

[Setup]
WindowVisible=yes

[Files]
Source: "back.bmp"; Flags: dontcopy

[Code]

procedure InitializeWizard();
var
  BackgroundImage: TBitmapImage;
begin
  BackgroundImage := TBitmapImage.Create(MainForm);
  BackgroundImage.Parent := MainForm;
  BackgroundImage.SetBounds(0, 0, MainForm.ClientWidth, MainForm.ClientHeight);
  BackgroundImage.Stretch := True;
  ExtractTemporaryFile('back.bmp');
  BackgroundImage.Bitmap.LoadFromFile(ExpandConstant('{tmp}\back.bmp'));
end;

For a slightly different implementation, see Background image during the installation on the ISXKB.
