class PASCALIMPLEMENTATION TCustomImageList : public System::Imagelist::TBaseImageList
TCustomImageList is the base class for collections of same-sized images, each of which can be referred to by its index.
Image lists manage large sets of icons or bitmaps. All images in an image list are contained in a single, wide bitmap in screen device format. An image list may also include a monochrome bitmap that contains masks that are combined with the images to produce a transparent effect such as is common in icons.
