GDImage (Complete graphic control for Windows 2000, XP, 2003, VISTA)
GDImage is a graphic image control provided under the form of a Win32 DLL.
GDImage controls are persistent, you'll never worry about redrawing when your window is minimized or temporarily covered, because they handle all the messy Windows details for you.
Create once... and forget, GDImage handles everything, automatically!
GDImage supports ARGB colors, this means RGB colors plus Alpha channel to perform alphablending (translucency).
GDImage supports a mix of bitmap and vectorial drawing.
GDImage allows you to use either child controls, popup layered windows, and/or popup shapped windows (a windows using a region based on a transparent bitmap color).
With GDImage you can create sprite animation, dynamic image rotation, and stunning visual effects.
GDImage can display overlay objects (image, text, line, arrow, rectangle, polyline, polypoligon, curve) they are floating above the image background as multiple transparent or opaque layers that can overlap.
You can change all object's properties on the fly: 
z-order, location, color, pen size, translucency, text string, draft or antialias mode.
With GDImage you can use a mix of GDI, GDI+, and OpenGL inside of the same image control !
