% This coder is a kind of backdoor used by the COM object that allows it to %
% pass blobs back and forth using the coder interface. It simply encodes and %
% decodes the filename as a comma delimited string and extracts the info it %
-% needs. The five methods of passing images are: %
-% %
-% FILE - same thing as filename so it should be a NOP %
-% IMAGE - passes an image and image info structure %
-% BLOB - passes binary blob containining the image %
-% STREAM - passes pointers to stream hooks in and does the hooking %
-% ARRAY - passes a pointer to a Win32 smart array and streams to it %
-% %
-% Of all of these, the only one getting any real use at the moment is the %
-% ARRAY handler. It is the primary way that images are shuttled back and %
-% forth as blobs via COM since this is what VB and VBSCRIPT use internally %
-% for this purpose. %
