We use computed fields with the bitmap() function to dynamically display pictures on datawindows.   We have also found that when displaying some smaller bitmaps in bitmap controls in datawindows ,setting the transparency to 1 smooths out rough edges and makes them look a lot better.   However, there does not appear to be a way to apply transapency to a computed field displaying a bitmap.  Any ideas?

In the attached image the same bitmap xg.bmp is placed on the datawindow as a computed field and as a bitmap with a 1% transparency.  You can see that the bitmap version is much smoother due to the transparency.
