Set Transparency Color with TadvSmoothListBox.Item

VCL TMS VCL UI Pack
1

Hi!



I've got different pictures in a TadvSmoothListBox. I want so make
clFuchsia the Transparency Color, like it usually works with TImage /
TPicture



But this does not seem to do the trick:



    a: TAdvSmoothImageListBox;



   for i := 0 to a.Items.Count - 1 do begin

     a.Items.Items.Caption.Text := a.Items.Items.FileName;

     a.Items.Items.Image.TransparentMode := tmAuto;  // or tmFixed / doesn't matter

     a.Items.Items.Image.Transparent := True;

     a.Items.Items.Image.TransparentColor := clFuchsia;

   end;





Transparency works fine for like .png files with transparency information stored. But how can i do this with bmps?



Thanks!

Unfortunately at this time, transparency is only supported for GIF & PNG formats where transparency is a built-in capability of the image format where for a bitmap, this is not available in the file format. We've added it on the feature request list though to investigate if we can find a workaround to have transparency based on the bottom-left pixel as is in other VCL components.
