Copying image to clipboard removes transparent background

Unity Engine

Hi,

So I am trying to add some code for the user to copy a Unity editor icon and paste it somewhere else. I managed to get it working but the background transparency is missing.

Here is the code:

using (Stream s = new MemoryStream(IconImage.width * IconImage.height))
{
    Texture2D textreCopy = new(IconImage.width, IconImage.height, IconImage.format, IconImage.mipmapCount > 1);

    Graphics.CopyTexture(IconImage, textreCopy);

    byte[] bits = textreCopy.EncodeToPNG();
    s.Write(bits, 0, bits.Length);

    System.Drawing.Image image = System.Drawing.Image.FromStream(s);

    System.Windows.Forms.Clipboard.SetImage(image);
}

I found out that the textreCopy variable is storing the correct alpha value but it is getting lost when using System.Drawing.Image.FromStream(s). I also tried to convert the colour information from the texture from RGBA to ARGB but this did not fix the issue.

Any help is appreciated.
