Delphi高级界面特效制作百例源代码,这是随书源代码部分,不知可否

unit Unit1;

// This little example shows how to create the illusion
// of your program painting directly on the desktop!
// If you have any ideas for improvements, please send
// the new version to me - you will ofcourse be credited.
// Particularly I'm looking for methods to make the
// drawing faster, although it's not HORRIBLY slow now.
//
// Note that: the illusion is lost if something changes
// underneath your form - this means that this effects
// is probably only useful for splash screens etc.
// If you can figure out how to make the image repaint
// when something changes underneath it, please write!
// Also note that I'm assuming the client area of the
// form is exactly the same size as the map and mask
// images.
//
// You can e-mail me at [e-mail]
