Subject: Have TBitmap, want TBitmapGraphic (and others)

Hi,

I'm an Envision newbie (using Envision files dated 1999.08.22). I have TBitmaps, which I want to manipulate using Envision. My problem is that TMyGraphic.Assign(myBitmap) results in a graphic with different colors from the original (T)bitmap. The colors are ok if I load the bitmap with TBitmapGraphic, but I'd like to have the initial bitmap in a TBitmap, in which case Envision (or my usage of it) gets into trouble.

procedure TForm1.btnConvertImageClick(Sender: TObject);
var
l_BmpGraphic : TBitmapGraphic;
l_bitmap: TBitmap;
begin
l_bitmap:=TBitmap.Create;
l_BmpGraphic := TBitmapGraphic.Create;
try
l_bitmap.LoadFromFile(txtSourceImageFileName.Text);

l_bmpGraphic.Assign(l_bitmap);
image1.Picture.Assign(l_bmpGraphic); //l_bmpGraphic has wrong colors
//....
finally
l_BmpGraphic.Free;
l_bitmap.Free;
end;
end;

Best regards,
