NTRODUCTION
The Alacron Picture OCX (Alpicture.ocx) provides an easy way for a user to display an image
from his application. It is not intended to be a high performance display object, but rather a load
and examine the image tool. It can display several images a second, and is depends on the
speed of the processor to do this. It does not take advantage of DirectX or OpenGL.

EFINITION
The Alpicture.ocx can be defined by it Interfaces Description which we present in the IDL used
to describe it. This OCX uses the MFC class library to leverage the predefined classes in MFC.
It can not claim to be a light weight control, but rather a multipurpose control.
