i created this just for fun; it seems a little easier to use.


ShapeForm.dll:

* Automatically resizes the form according to the image.
* Supports mouse dragging by default.
* Supports form transparency by default.
* Bmp form does not overlay on the InnoSetup's components, 
  so they will show up on the Bmp form.

* Does not require extra work; everything is automated.

ImageMasker.exe:

* Drag and drop a PNG file onto this; it will generate mask.bmp and base.bmp.
* Requires Visual C++ Redistributable 2015 or later.

Functions:

function zCreateRgnFromBmp(WndH: HWND; const sMaskBmp: WideString; iTrRGBColor: Integer): Integer;

function zCreateFormFromBmp(WndH: HWND; const sBmpFile: WideString; bACPremultiplied: Boolean): Integer;

function zCreateFormFromBmpEx(WndH: HWND; const sBmpFile: WideString; bACPremultiplied, bDraggableForm: Boolean; iOpacityPct: Byte): Integer;

Example:

procedure InitializeWizard();
begin
  ExtractTemporaryFile('mask.bmp');
  ExtractTemporaryFile('base.bmp');

  { ShapeForm }
  zCreateRgnFromBmp(WizardForm.Handle, ExpandConstant('{tmp}\mask.bmp'), clBlack);

  zCreateFormFromBmpEx(WizardForm.Handle, ExpandConstant('{tmp}\base.bmp'), False, True, 100);

end;
