TDib Class

A device-independent bitmap (DIB) has no GDI handle like a regular bitmap, although it does have a global handle.

Instead, it is just a structure containing format and palette information and a collection of bits (pixels). The TDib class provides a convenient way to work with DIBs like any other GDI object. The memory for the DIB is in one chunk allocated with the Windows GlobalAlloc functions, so that it can be passed to the Clipboard, an OLE server or client, and others outside of its instantiating application.
