How to make a image transparent [duplicate] - inno-setup

Question

How do I WelcomeLabel on Inno Setup does not appear and leave only the text over the image.
This is that i want.

Answer 1

Something like this might do the trick. Since the welcome labels don't support transparency, you need to workaround this by creating your own with a different class (that has a transparency support), inherit the parent, font, text and size and hide the original ones. Here is the script how to do this:
[Code]
procedure InheritBoundsRect(ASource, ATarget: TControl);
begin
ATarget.Left := ASource.Left;
ATarget.Top := ASource.Top;
ATarget.Width := ASource.Width;
ATarget.Height := ASource.Height;
end;
procedure InitializeWizard;
var
TopWelcomeLabel: TLabel;
BottomWelcomeLabel: TLabel;
begin
WizardForm.WizardBitmapImage.Align := alClient;
WizardForm.WizardBitmapImage.Bitmap.LoadFromFile('D:\Image.bmp');
TopWelcomeLabel := TLabel.Create(WizardForm);
TopWelcomeLabel.Parent := WizardForm.WelcomeLabel1.Parent;
TopWelcomeLabel.Font := WizardForm.WelcomeLabel1.Font;
TopWelcomeLabel.Caption := WizardForm.WelcomeLabel1.Caption;
TopWelcomeLabel.WordWrap := WizardForm.WelcomeLabel1.WordWrap;
InheritBoundsRect(WizardForm.WelcomeLabel1, TopWelcomeLabel);
WizardForm.WelcomeLabel1.Visible := False;
BottomWelcomeLabel := TLabel.Create(WizardForm);
BottomWelcomeLabel.Parent := WizardForm.WelcomeLabel2.Parent;
BottomWelcomeLabel.Font := WizardForm.WelcomeLabel2.Font;
BottomWelcomeLabel.Caption := WizardForm.WelcomeLabel2.Caption;
BottomWelcomeLabel.WordWrap := WizardForm.WelcomeLabel2.WordWrap;
InheritBoundsRect(WizardForm.WelcomeLabel2, BottomWelcomeLabel);
WizardForm.WelcomeLabel2.Visible := False;
end;
And the result:

Answer 2

I'm afraid what you want may not be possible or rather difficult, even if creating a custom page. Have a look at the CreateCustomPage() function and the example scripts included with your Inno Setup installation.

Answer 3

This code can help you. Just change the Welcome page, but you can try with other pages of the installer.
[code]
function NextButtonClick(CurPageID: Integer): Boolean;
begin
Result := True;
end;
function GetCustomSetupExitCode(): Integer;
begin
Result := 1;
end;
