Hello!
Glyph should not be Nil and PixelFormat should be pf32bit, please check it.

[Koushik Halder]

What you have mentioned, already there but not working. It will be better if you provide a DEMO.

[Support]

This Glyph is nil when event occurs.
If Glyph must be used then developer should create it here.
The GetBitMap procedure doesn’t create an image, you can use the sAlphaImageList1.CreateBitmap32 function.

[Koushik Halder]

The Image is stored in sImageList1. The Image Index is = 0. As per your suggestion I have added the following code:

procedure TForm1.sSkinManager1GetMenuExtraLineData(FirstItem: TMenuItem;
  var SkinSection, Caption: string; var Glyph: TBitmap;
  var LineVisible: Boolean);
begin
  if FirstItem = MenuItem1 then
    begin
      LineVisible := True;
      Caption := 'HorizontalMenuItem1';
      sAlphaImageList1.CreateBitmap32(1, 20, 20, 20);
    end;
end;

But no Glyph is shown in ExtraLineData. Please provide one DEMO.

Using the following code from ASLDemo the glyph is created:

      Glyph := TBitmap.Create;
    // Prepare Transparent Background
    Glyph.Canvas.Brush.Color := clFuchsia;
    Glyph.Canvas.FillRect(Rect(0, 0, Glyph.Width, Glyph.Height));
    Glyph.Transparent := true;
    // Receiving From ImageList
    sAlphaImageList1.DrawingStyle := dsTransparent;
    sAlphaImageList1.GetBitmap(1, Glyph);

But the Image quality gets distorted.
The Image 00001.png

becomes 00002.png

instead of 00003.png

How to improve the quality.

Why the code Glyph := TBitmap32.Create; does not work?

But no Glyph is shown in ExtraLineData. Please provide one DEMO.

Demo of ExtrLine may be found in the ASkindemo.
Look this procedure there:

procedure TMainForm.sSkinManager1GetMenuExtraLineData(FirstItem: TMenuItem; var SkinSection, Caption: string; var Glyph: TBitmap; var LineVisible: Boolean);

The glyph may be invisible if AlphaChannel exists there but empty (glyph is drawn as fully transparent in this case).

But the Image quality gets distorted.
Try to make new glyph with size of ImageList, which result will be?

[Koushik Halder]

I have already done but the result is the same. I think the problem is due to the 32Bit image conversion to 24Bit.
How to use TBitmap32.Create;
I have just uploaded my project. Please see.

Thank you. Try this:

procedure TForm1.sSkinManager1GetMenuExtraLineData(FirstItem: TMenuItem;
  var SkinSection, Caption: string; var Glyph: TBitmap; var LineVisible: Boolean);
begin
  Glyph := TBitmap.Create;
  Glyph.Width := sAlphaImageList1.Width;
  Glyph.Height := sAlphaImageList1.Height;
  sAlphaImageList1.GetBitmap32(0, Glyph);
end;

If you make pf24bit, then transparent part is lost.
