Animate Image Component -TAnimateImage is a windowed control similar to TImage for displaying images of an image list on a form. You only need to assign a TImageList component (or its descendant) to its Images property, and set the FrameIndex property to the index of your desired image on the image list. Of course, TAnimateImage can animate images of an image list too. If you have frames of an animation as Bitmap or Icon, this component offers the easiest way to animate them. For this purpose, TAnimateImage provides some properties to specify interval, segment, and direction of images for the animation.
