Transparent Form :

You have to define a Region (with CreateRectRgn, CombineRgn) and to set
this region for the form's window (with SetWindowRgn).
To define the region, you have to analyse the bitmap to find the
transparent color region.

Have a look to Delphi Super Page (I can't remember the address you'll find
it with a search engine), and try to find a project named CoolForm.

Anti-aliasing :

If you know how antialiasing works you can retrieve and set the color of a
bitmap pixel by using the property pixel of the bitmap's canvas .
